The principal symptoms are fever, congestion of the ocular conjunctivae, reddening of the lips and oral cavity, protuberance of tongue papillae, and edema or erythema of the extremities.
Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE.

A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information.

Autologous vein-coated stent for exclusion of a coronary artery aneurysm: case report with postimplantation intravascular ultrasound characteristics. (1/370)

This report describes the successful use of an autologous cephalic vein-coated coronary stent to exclude an aneurysm of the distal right coronary artery. Post-implantation angiography confirmed successful exclusion of the aneurysm with no evidence of leakage. Intravascular ultrasonography showed complete apposition of the stent to the arterial wall proximal and distal to the aneurysm. The vein could be seen clearly around the stent. Symmetrical stent expansion (minimal luminal diameter, 2.8 mm) was verified. Increased echogenicity in the excluded aneurysm indicated early thrombus formation. Evidently, this is the 1st report of the successful use of an autologous cephalic vein-coated coronary stent to exclude an aneurysm of the distal right coronary artery.  (+info)

Exercise-induced myocardial ischemia in isolated coronary artery ectasias and aneurysms ("dilated coronopathy"). (2/370)

OBJECTIVES: The purpose of our study was to evaluate the clinical significance of isolated coronary artery ectasias or aneurysms (CEA). BACKGROUND: It has been postulated that altered coronary blood flow in CEA predisposes patients to the development of myocardial ischemia (CI) and infarction. METHODS: Sixty-seven patients with bilateral nonobstructive CEA without associated cardiac defects ("dilated coronaropathy") were derived from 16,341 cardiac catheterizations between 1986 and 1997. Ectasias were defined as luminal dilation of 1.5- to 2.0-fold, aneurysms of >2.0-fold of normal limits. Eleven of 25 patients presented with myocardial infarction due to an occlusion of the infarct vessel. In 42 patients without infarction (study group), exercise-induced CI was investigated. RESULTS: A corresponding CI was documented in 32 of 42 patients in a coronary sinus lactate study (reduced lactate extraction 5.6 +/- 4.1%) and in 29 of 40 patients in an ergometry (0.25 +/- 0.06 mV ST depressions). The results differed significantly from a control group of 29 patients without heart disease (p < 0.001). Nitroglycerin (0.8 mg) provoked a further significant deterioration of CI in the 32 of 42 developing a frank cardiac lactate production (-2.6 +/- 6.8%, p < 0.001). The metabolic extent of CI was significantly correlated to the coronary diameters of the proximal and middle segments of left anterior descending artery and the middle segment of left circumflex artery (r = 0.87, p < 0.001). Stigmata of an impaired coronary blood flow such as delayed antegrade filling, segmental backflow phenomenon and local deposition of dye were found significantly more often with increasing coronary diameters (p < 0.04). CONCLUSIONS: "Dilated coronaropathy" is an entity of nonobstructive, ischemic coronary artery disease. Nitroglycerin is of no therapeutic benefit but leads to an aggravation of exercise-induced CI.  (+info)

Kawasaki disease: a maturational defect in immune responsiveness. (3/370)

Kawasaki disease (KD), an acute febrile disease in children of unknown etiology, is characterized by a vasculitis that may result in coronary artery aneurysms (CAAs). In new patients with KD, a selective and prolonged T cell unresponsiveness to activation via the T cell antigen receptor CD3 was observed, whereas proliferation to other stimuli was intact. This "split T cell anergy" delineated KD from other pediatric infections and autoimmune diseases and correlated with CAA formation (P<.001). A transient immune dysfunction was also suggested by an incomplete responsiveness to measles-mumps-rubella (MMR) vaccination in patients with KD versus controls (P<.0001; odds ratio, 15.6; 95% confidence interval, 4.8-51.1), which was overcome by revaccination(s). The reduced responsiveness to MMR in patients with KD suggests a subtle and predetermining immune dysfunction. An inherent immaturity to clear certain antigens may be an important cause that precipitates KD and the immune dysregulation during acute disease.  (+info)

Transthoracic echocardiography using second harmonic imaging: diagnostic alternative to transesophageal echocardiography for the detection of atrial right to left shunt in patients with cerebral embolic events. (4/370)

OBJECTIVES: We sought to evaluate whether transthoracic contrast echocardiography using second harmonic imaging (SHI) is a diagnostic alternative to transesophageal contrast echocardiography (TEE) for the detection of atrial right to left shunt. BACKGROUND: Paradoxic embolism is considered to be the major cause of cerebral ischemic events in young patients. Contrast echocardiography using TEE has proven to be superior to transthoracic echocardiography (TTE) for the detection of atrial shunting, SHI is a new imaging modality that enhances the visualization of echocardiographic contrast agents. METHODS: We evaluated 111 patients with an ischemic cerebral embolic event for the presence of atrial right to left shunt using an intravenous (IV) contrast agent in combination with three different echocardiographic imaging modalities: 1) TTE using fundamental imaging (FI); 2) TTE using SHI; and 3) TEE. The severity of atrial shunting and the duration of contrast visibility within the left heart chambers were evaluated for each imaging modality. Image quality was assessed separately for each modality by semiquantitative scoring (0 = poor to 3 = excellent). Presence of atrial right to left shunt was defined as detection of contrast bubbles in the left atrium within the first three cardiac cycles after contrast appearance in the right atrium either spontaneously or after the Valsalva maneuver. RESULTS: A total of 57 patients showed evidence of atrial right to left shunt with either imaging modality. Fifty-one studies were positive with TEE, 52 studies were positive with SHI, and 32 were positive with FI (p<0.001 for FI vs. SHI and TEE). The severity of contrast passage was significantly larger using SHI (61.6+/-80.2 bubbles) compared to FI (53.7+/-69.6 bubbles; p<0.005 vs. SHI) but was not different compared to TEE (43.9+/-54.3 bubbles; p = NS vs. SHI). The duration of contrast visibility was significantly longer for SHI (17.4+/-12.4 s) compared to FI (13.1+/-9.7 s; p<0.001) and TEE (11.9+/-9.6 s; p<0.02). Mean image quality improved significantly from FI (1.5+/-0.8) to SHI (2.0+/-0.8; p<0.001 vs. FI) and TEE (2.5+/-0.7; p<0.001 vs. SHI). CONCLUSIONS: In combination with IV contrast injections, TEE and SHI have a comparable yield for the detection of atrial right to left shunt. Both modalities may miss patients with atrial shunting. In young patients with an unexplained cerebrovascular event and no clinical evidence of cardiac disease, a positive SHI study may obviate the need to perform a TEE study to search for cardiac sources of emboli.  (+info)

The impact of untreated coronary dissections on acute and long-term outcome after intravascular ultrasound guided PTCA. (5/370)

AIM: Vessel size adapted PTCA results in the use of larger balloons with an increased incidence of severe vascular dissections. The aim of our trial was (a) to evaluate the effect of severe dissections on the acute outcome and (b) to study the natural history of dissections after 1 year. METHODS AND RESULTS: One hundred and seventy-eight patients with 195 lesions underwent vessel size adapted PTCA using intravascular ultrasound. Clinical and angiographic 1 year follow-up was obtained for all patients. Intravascular ultrasound was performed before PTCA to measure the external elastic membrane diameter at the lesion site so that the balloon size could be adopted (external elastic membrane-10%) and post-interventionally to determine the procedural success and the incidence of intracoronary dissections. Stent implantation was reduced to persistently flow limiting dissections (TIMI I, II). Dissections were detected by intravascular ultrasound in 128/195 (66%) lesions (by angiography in 111/195 [58%] lesions) and classified by intravascular ultrasound criteria into four groups: group I: no dissection (67 lesions [34%]), group II: mild dissections (21 lesions [11%]), group III: medium dissections (19 lesions [10%]) and group IV: severe dissections (88 lesions [45%]). Because of threatened vessel closure, GPIIb/IIIa antagonists were used in eight (4.5%) patients and a stent was implanted in two (1. 1%) patients. The cumulative event rate after 1 year was 12% and the global angiographic restenosis rate was 19%. The post-interventional evidence of severe dissections was associated with a decrease in clinical events during long-term follow up (group I: 13 events [19%] vs group IV: seven events [7%];P=0.03). This was also true for the occurrence of restenosis which was significantly lower in patients with severe dissections (group I: 19 [28%] lesions vs group IV:10 [11%] lesions;P=0.01). CONCLUSIONS: According to the theory of 'therapeutic dissections', our data suggest that substantial dissections following PTCA, which do not diminish antegrade blood flow, do not lead to an increase in acute or long-term events. The natural history of vessel injury seems to provide favourable wound healing without increase of restenosis. Thus, stenting for treatment of large dissections without flow limitation does not seem to be mandatory.  (+info)

Greater late lumen loss after successful coronary balloon angioplasty in the proximal left anterior descending coronary artery is not explained by extent of vessel wall damage or plaque burden. (6/370)

OBJECTIVES: We investigated whether the greater late lumen loss after coronary balloon angioplasty in the proximal left anterior descending artery (P-LAD) compared with that in other segments might be related to differences in vascular dimensions or morphology as determined by angiography and intravascular ultrasound imaging. BACKGROUND: The greater late lumen loss after angioplasty in the P-LAD that has been observed in several studies has not been explained. METHODS: We studied 178 patients and 194 coronary artery lesions by quantitative angiography and 30 MHz intravascular ultrasound imaging after successful balloon angioplasty. Vessel wall morphology was compared among three proximal and three nonproximal segments. Follow-up quantitative angiography for late lumen loss calculation was performed in 168 lesions. Multivariate analysis was used to determine predictors of late lumen loss. RESULTS: Absolute and relative late loss were significantly greater at the P-LAD compared with the pooled group of other segments (0.42 +/- 0.60 mm vs. 0.10 +/- 0.48 mm, p = 0.0008 and 0.14 +/- 0.24 vs. 0.03 +/- 0.17, p < 0.001). Also, a greater percentage of calcific lesions (65% vs. 44%, p = 0.034), a lower incidence of rupture (51% vs. 74%, p = 0.009) and a larger reference segment plaque area (5.4 +/- 2.2 mm2 vs. 4.7 +/- 1.9 mm2, p = 0.05) were found in the P-LAD. In multivariate analysis however, these variables were not predictive of late loss. CONCLUSIONS: Greater late lumen loss after coronary balloon angioplasty of the P-LAD is not explained by differences in atherosclerotic plaque burden or in vessel wall damage.  (+info)

Long term consequences of regressed coronary aneurysms after Kawasaki disease: vascular wall morphology and function. (7/370)

OBJECTIVES: To investigate the long term consequences of regressed aneurysms after Kawasaki disease, using follow up coronary angiography; to assess the vascular wall morphology at the site of the aneurysms by intravascular ultrasound imaging; and to evaluate the function of the affected vessels using intracoronary infusions of acetylcholine and isosorbide dinitrate. DESIGN: 33 patients were studied, 27 with previous Kawasaki disease and six with congenital heart disease. All Kawasaki disease patients were followed for more than 10 years from disease onset. The 33 patients comprised four groups: group 1 included 13 Kawasaki disease patients with a total of 23 sites of regressed large sized (>/= 4 mm) coronary aneurysms; group 2 included 13 Kawasaki disease patients with 22 sites of regressed small sized (< 4 mm) coronary aneurysms (four patients had sites of both large and small sized aneurysms); group 3 included a further five Kawasaki disease patients with 25 normal coronary angiography sites in the acute stage of Kawasaki disease; and group 4 comprised the six patients with congenital heart disease as controls, with a total of 27 normal coronary angiography sites. During coronary angiography, 15 microg of acetylcholine and 0.5 mg isosorbide dinitrate were infused into the coronary artery. The luminal diameter at the sites was measured using a cine-videodensitometric analyser, to assess the distensibility of the coronary artery wall. RESULTS: Coronary angiography in all 22 patients in groups 1 and 2 and in all the patients in group 3 was normal, with no stenoses and no irregularity of the arterial wall. However, the intravascular ultrasound imaging in groups 1 and 2 showed various degrees of the intimal thickening. In groups 1 and 2, there was significantly more vascular constriction with acetylcholine, and poorer dilatation with isosorbide dinitrate than in groups 3 or 4 (each p < 0.05, respectively). There was no difference between group 3 and group 4 in response to either acetylcholine or isosorbide dinitrate, CONCLUSIONS: There is evidence of persisting abnormal vascular wall morphology and vascular dysfunction at the site of regressed coronary aneurysms in patients with previous Kawasaki disease. These patients should be counselled to avoid potential risk factors for atherosclerosis, and long term follow up is needed into adult life.  (+info)

Outcome from balloon induced coronary artery dissection after intracoronary beta radiation. (8/370)

OBJECTIVE: To evaluate the healing of balloon induced coronary artery dissection in individuals who have received beta radiation treatment and to propose a new intravascular ultrasound (IVUS) dissection score to facilitate the comparison of dissection through time. DESIGN: Retrospective study. SETTING: Tertiary referral centre. PATIENTS: 31 patients with stable angina pectoris, enrolled in the beta energy restenosis trial (BERT-1.5), were included. After excluding those who underwent stent implantation, the evaluable population was 22 patients. INTERVENTIONS: Balloon angioplasty and intracoronary radiation followed by quantitative coronary angiography (QCA) and IVUS. Repeat QCA and IVUS were performed at six month follow up. MAIN OUTCOME MEASURES: QCA and IVUS evidence of healing of dissection. Dissection classification for angiography was by the National Heart Lung Blood Institute scale. IVUS proven dissection was defined as partial or complete. The following IVUS defined characteristics of dissection were described in the affected coronary segments: length, depth, arc circumference, presence of flap, and dissection score. Dissection was defined as healed when all features of dissection had resolved. The calculated dose of radiation received by the dissected area in those with healed versus non-healed dissection was also compared. RESULTS: Angiography (type A = 5, B = 7, C = 4) and IVUS proven (partial = 12, complete = 4) dissections were seen in 16 patients following intervention. At six month follow up, six and eight unhealed dissections were seen by angiography (A = 2, B = 4) and IVUS (partial = 7, complete = 1), respectively. The mean IVUS dissection score was 5.2 (range 3-8) following the procedure, and 4.6 (range 3-7) at follow up. No correlation was found between the dose prescribed in the treated area and the presence of unhealed dissection. No change in anginal status was seen despite the presence of unhealed dissection. CONCLUSION: beta radiation appears to alter the normal healing process, resulting in unhealed dissection in certain individuals. In view of the delayed and abnormal healing observed, long term follow up is indicated given the possible late adverse effects of radiation. Although in this cohort no increase in cardiac events following coronary dissections was seen, larger populations are needed to confirm this phenomenon. Stenting of all coronary dissections may be warranted in patients scheduled for brachytherapy after balloon angioplasty.  (+info)

Background: Children with giant coronary artery aneurysms (CAA) after Kawasaki disease (KD) are at substantial risk of thrombosis. There are currently no evidence-based guidelines for optimal thromboprophylactic therapy in these children.. Methods: The North American Kawasaki Disease Registry was queried to identify all patients with giant CAA (maximum coronary artery z-score ,10) and their antithrombotic therapy. Freedom from thrombosis was modelled using the Kaplan-Meier method; thrombotic complication rate was calculated per patient-year/month of follow-up.. Results: n=202 patients with giant CAA were included, of whom 28 (14%) experienced either coronary artery thrombosis with or without myocardial infarction. Freedom from thrombotic complications was 92%, 85% and 79% at 3 months, 5 and 10 years after diagnosis, respectively. Non-pharmacological factors associated with increased risk of thrombotic complications included higher maximum coronary artery z-scores (HR: 1.7/+10 SD, p,0.001), ...

Prior efforts to study SCAD have been hampered by underrecognition and lack of registry-based studies. Risk factors and pathogenesis remain largely undefined, and inheritability has not been reported. OBSERVATIONS Using novel research methods, patient champions, and social media, the Mayo Clinic SCAD Registry has been able to better characterize this condition, which was ...
Spontaneous coronary artery dissection (SCAD) is a rare cause of acute coronary syndrome and sudden cardiac death with high predilection for premenopausal women. The overall incidence of SCAD in patients referred for coronary angiography has been reported to vary between 0.1% and 1%. In a series of 94 antemortem and postmortem cases the mean age for men was 46 years and the mean age for women was 39 years. In this series, the dissection of right coronary artery was more common in men while the left coronary artery system was most commonly affected in women. Although the precise etiology of SCAD remains unclear, several risk factors such as atherosclerosis, connective tissue disorder, peri-partum episode, and trauma have been postulated. Consequently, SCAD could result in a wide spectrum of presentations ranging from chest pain to extensive myocardial infarction. Notably, sudden cardiac death has been a common mode of clinical presentation in many previously reported cases. While the definitive diagnosis
Study Start Date: April 2014. Spontaneous Coronary Artery Dissection (SCAD) is an unpredictable event in which patients typically first present with a sudden, unexpected heart attack. The condition can affect all age groups and is recognised as a cause of heart attacks in young adults. Although both men and women can be affected by SCAD, the condition is more common in women, particularly during or shortly after pregnancy.. SCAD results from an acute bleed into the vessel wall of a coronary artery creating a false lumen (a lumen is the term for the inside of a blood vessel, the tube down which the blood is supposed to flow). This accumulation of blood compresses the true lumen, restricting or preventing blood flow to the heart muscle. Little is currently known about the underlying causes of SCAD and its long-term outcomes, or indeed, how best to treat it. (Picture below shows angiographs of vessel before (A) and after (B) stenting.). ...
Primary spontaneous coronary artery dissection (SCAD) remains a rare presentation of acute coronary syndrome, with a prevalence of around 0.1%-0.4%.(1) Dissection of the coronary intima or media leads to the formation of a false lumen. This false lumen may expand and propagate, obstructing flow within the true lumen, which may produce symptoms of myocardial ischaemia. Women who are in gestation or the peripartum period, with no classical cardiovascular risk factors, appear to have the highest risk.(2) It has been hypothesised that the aetiology of SCAD in women is hormonal balance and appropriate pregnancy-related changes to cardiovascular physiology.(3) In contrast, SCAD in men is principally preceded by substance abuse or extreme physical activity. The latter is thought to increase shear stress, leading to an intimal tear, which was the case in our patient. Recent studies have found a strong association between fibromuscular dysplasia and SCAD; however, the true prevalence remains unknown.(4) ...
Spontaneous coronary artery dissection (SCAD) remains a rare cause of acute coronary syndrome. SCAD has been observed in three groups of patients: those with coronary atherosclerosis, women in the peripartum period, and an idiopathic group. SCAD may also be associated with some other conditions. Herein, we present a 57 year-old man who developed SCAD concomitant with Trousseaus syndrome secondary to colon adenocarcinoma.

Long term objective:Discover molecular and cellular mechanisms of SCAD and develop biomarkers to enable prediction and prevention.. The purpose of the research is to identify mutations (defects in the genetic blueprint) that cause tears in blood vessels that supply the heart. Some mutations may be inherited (passed on) from a parent without an apparent blood vessel problem while others may develop for the first time in the affected person. The study includes individuals diagnosed with spontaneous coronary artery dissection and their biological parents.. Adults with SCAD will be identified both retrospectively and prospectively.Confirmation of the diagnosis by review of coronary angiography will be required before proceeding with the informed consent process and blood or saliva sample procurement. ...

Results:. Prevalence of medication use by risk levels (RL) was explored across 3 eras (1999-2004, 2005-2010, and 2011-2016). Acetylsalicylic Acid (ASA): Use of ASA/aspirin ranged from 88 to 96% for RLs for which use was indicated (RLs 3.1, 4.1, 4.2, 5.1, 5.2, and 5.3); this represents patients with coronary artery aneurysms of any size that have not regressed to normal luminal dimensions or dilation only (z-score ,2.5). Systemic anticoagulation is only recommended for patients for RL 5.1 (persistent large/giant coronary artery aneurysms). Despite this, only 65% of patients in RL 5.1 were receiving anticoagulation and there was no trend toward increased usage over the different year groups.. Dual antiplatelet therapy (ASA and clopidogrel) was in use at 16% of patient visits for RL 5.2 where use was reasonably indicated. For visits for RLs 5.3 and 5.4, dual antiplatelet therapy was used for 11% and 9%, respectively (not indicated).. There was an increase in ASA use for RL 3.2 from 54% in ...
Coronary artery aneurysm is an abnormal dilatation of part of the coronary artery. Acquired causes include atherosclerosis, Kawasaki disease and coronary catheterization. It can also be congenital. It is often found coincidentally on coronary angiography. Generally, it has a good prognosis. In Kawasakis disease, untreated, there is a 1-2% death rate, from cardiac causes.

Background: Drug-eluting stents (DES) may induce toxic effects on the coronary arterial wall such as aneurysm formation, incomplete stent apposition, stent thrombosis and vessel rupture based on the experimental studies. We investigated the incidence and characteristics of arteriopathy at 6 month routine angiographic follow up after DES implantation regardless of clinical events in a single center unrestricted DES registry.. Methods: A total 614 consecutive patients (pts, Male 278, mean age 63.12±10.89 years) who were treated with DES (Sirolimus-SES and/or Paclitaxel-PES) were enrolled. We performed routine angiographic follow up at 6 months regardless of clinical events and IVUS was done in case of angiographic aneurismal change at the DES implanted site was observed.. Results: Conventional coronary risk factors were not different compared with control study population. The incidence of coronary aneurysm was 3.1 % (19/614). Among the 19 coronary aneurysm patients (pts, Male 16, Age 61.68± ...
We present our recent casuistry on such an interesting issue as coronary dissections. Provide data to assist the diagnosis and treatment of this disease.
Who gets it?. Typically, it affects women below the age of 50 years of age. Women outnumber men by a ratio of 9:1. SCAD is considered a rare cause of heart attacks. It probably is responsible for about 4% of all heart attacks. In women aged 50 or less it probably accounts of 25-35% of all heart attacks. The proportion is even higher in pregnant women.. Why does it happen?. We dont know for sure. It is believed that especially in pregnancy, hormonal changes (in the third trimester and during childbirth and even in the immediate period after delivery can make the arterial walls more vulnerable and weak. What we dont know for sure is whether it is just about the pregnancy or whether the patient themselves have an underlying propensity to start off with. What we do know is that people with very tortuous coronary arteries seem to be more predisposed to SCAD.. Several conditions can cause an underlying propensity to a weaker coronary artery walls.. These include:. 1) Fibromuscular dysplasia (about ...
October 12, 2012. Thank you Bob and family for this wonderful website and for supporting SCAD research! My SCAD was in 2003, after the birth of my second son. I was 38 and had a widow maker tear at the fork of the LAD, so had double bypass surgery. Today, it feels as though all that happened to a different person. Although SCAD can recur, I dont dwell on that. My focus is my boys future and other women out there who are being misdiagnosed or ignored in the ER.. With deep appreciation to the Alicos, I look forward to knowing all the the SCAD women who are finding this site and gaining comfort. Were in this together! Best, Katherine. ...
Pregnancy-associated hormonal and hemodynamic changes and coronary shear stress have been hypothesized as contributing to P-SCAD (12). Within the first 6 weeks of pregnancy, notable hemodynamic changes begin to occur, including expansion of blood volume, increase in red cell mass, reduction of systemic vascular resistance, and increased cardiac output (13). By the end of pregnancy, plasma volume increases by 30% to 50% for a total of 4.7 to 5.2 l (14,15). Cardiac output increases from 4 to 5 l/min at baseline to 6 to 7 l/min during the second trimester and peaks as high as 10 to 11 l/min during labor. In conjunction with active Valsalva efforts (pushing) in the second stage of labor, these physiological adaptations may hypothetically contribute to regional demands on the coronary arteries and precipitate SCAD. Although it is possible for SCAD patients to develop subclinical coronary intramural hematomas intrapartum, leading to a SCAD MI, the highest frequency of P-SCAD did not occur during ...

January 31, 2020. January 6th of this year, I was out walking with friends and complaining of being overly hot and out of breath. During the prior week I had had intermitent sharp pain in my left underarm region, some indigestion, I vomited once, and felt at times sweaty and chilled. I had also gone through some significant emotional holiday stress. My friends insisted that I go to the ER and they probably saved my life. I spent three days there, with the usual tests, and the angiogram confirmed the SCAD diagnosis.. My cardiologist has placed me on Toprol XL, Plavix and a baby aspirin. She said to rest for the month and then begin cardio rehab. I describe this month of rest as a triangle of Anxiety, Heart, and Meds. I dont know which is influencing the others. I have anxiety about the care I am receiving and whether there is hope for a good long-term outcome. I have great concern for my heart. And I wonder if the medication, which makes me fatigued, dizzy, bruised, and confused is helping or ...

Kawasaki disease is an acute febrile illness that usually occurs in children younger than 5 years of age. The use of intravenous immunoglobulin (IVIG) within the first 10 days of illness has been shown to reduce the incidence of coronary artery aneurysms significantly. The relative roles of repeated doses of intravenous immunoglobulin (IVIG) are controversial in refractory Kawasaki disease (KD). Most experts recommend the second retreatment with IVIG, 2 g/kg in refractory KD. However, the dose-response effect of the third or fourth IVIG was uncertain. Although there have been a significant number of reports on new therapeutic options for refractory KD, such as steroid, infliximab, methotrexate, and other immunosuppressants, their effectiveness in reducing the prevalence of coronary artery aneurysms was unproven. We present here KD patient with small coronary artery aneurysm who is resistant to the third IVIG and steroid pulse therapy but showed improvement immediately after the infusion of the
Aneurysmal coronary artery disease is characterised by abnormal dilatation of a localised or diffuse segment of the coronary artery tree. Before the advent of coronary angiography, all reported cases were based on postmortem findings. The largest angiographic series is the Coronary artery surgery study (CASS) registry where 4.9% of 20 087 patients were observed at angiography to have coronary artery aneurysms.1 In this series, a coronary artery aneurysm was defined as a dilatation with a diameter of ⩾ 1.5 times the adjacent normal coronary artery. Ninety per cent of these were associated with atherosclerotic coronary artery disease, where vessel ectasia and poststenotic dilatations are not an infrequent finding. Tunick et al in their series,2 used the term discrete aneurysm to mean a localised spherical or saccular shaped dilatation of ⩾ 1.5 times. They excluded fusiform aneurysms as they felt that these may be confused with vessel ectasia. In their series of 8422 patients an incidence of ...
Spontaneous coronary artery dissection (SCAD) is a rare but often fatal cause of ischaemic heart disease occurring predominantly in young or middle aged, otherwise healthy subjects. Although about 250 cases of SCAD have been reported in the literature, to the best of our knowledge, spontaneous three vessel coronary dissection associated with typical effort angina has never been reported. This case illustrates coronary angiography and intravascular ultrasound images in a patient with SCAD involving all three vessels and treated by stenting.. A 57 year old man presented with exertional chest pain. His risk factors included smoking, hypertension, and hyperlipidaemia. ECG showed an abnormal Q wave in lead III and 1 mm ST depression in III, aVF. Technetium-99m sestamibi SPECT image showed a moderate fixed defect in the inferior wall and a reversible defect in the anterior wall. Selective coronary angiography revealed SCAD involving all three vessels. Right coronary angiogram showed linear dissection ...
In adults, CAA is predominantly atherosclerotic in origin however, other causes include Kawasaki disease, autoimmune disease, trauma, infection, dissection, congenital malformation and angioplasty [1, 24]. Recently, with the advent of implantation of drug eluting stents there are increasing reports suggesting stents causing coronary aneurysm months or years after the procedure [1, 14, 22, 24]. The proposed pathogenesis of stent-related aneurysm formation is multi-factorial. The drug-eluting stent contains immunosuppressant such as Sirolimus, which inhibits inflammation, or chemotherapeutic agents like Paclitaxel, which is an anti-inflammatory agent and inhibits cell proliferation. In due course of time, once drug is eluted, the polymer in which the drug is embedded may elicit a hypersensitivity reaction and vasculitis and results in weakening of vessel wall and subsequent dilatation [1, 14, 22, 24]. Mechanical damage to the arterial wall during balloon angioplasty and stent placement or ...

Ischemic heart disease (IHD) may coexist with aorto-iliac occlusive disease, and concomitant revascularization procedures may be required. This study reports our experience with ascending aorta to left femoral bypass grafting (Ao-ltFG) to prepare for intra-aortic balloon pumping (IABP). A 73-year-old man with chest pain was admitted to our hospital. Coronary angiography revealed coronary aneurysm and IHD. Enhanced computed tomography showed coronary aneurysm, complete left subclavian artery occlusion and bilateral external iliac artery occlusion. We planned a two-stage operation. In the first operation, we chose coronary artery bypass grafting, excision of the coronary aneurysm and simultaneously Ao-ltFG to prepare for IABP. In the second operation, we chose axillo-axillo bypass grafting and Ao-ltFG to right femoral artery bypass grafting. Although in the operative findings no coronary aneurysm was recognized, we performed the other operations and the postoperative course was uneventful without ...
Spontaneous coronary artery dissection (SCAD) which was first described by Pretty in 1931 is rare but significant cause of myocardial infarction and sudden cardiac death. The incidence of this condition in general population is between 0.28% and 1.1%, however in pregnant population it accounts for 27% of all MI cases.1 Mode of presentation is variable and can range from asymptomatic pathology to MI and sudden cardiac death. In the past, sudden cardiac death was the most common presentation with 70% of diagnoses was made at the time of autopsy. 36 years old G3P1+1 at 38 weeks of gestation admitted to delivery suite with spontaneous labour and delivered a live male baby. Two hours after delivery, she started complaining of central chest pain which was radiating to back and left arm along with vomiting. She was haemodynamically stable with normal oxygen saturation. Immediate blood gases, chest x-ray and troponin levels were all normal. However ECG demonstrated inferior ST segment elevation. A Tran ...

Coronary-to-cardiac chamber fistulae and coronary aneurysms are potential complications after heart transplantation. In the setting of exercise intolerance and large fistulae at major coronary vessels, covered stents may provide an effective interventional strategy.
Background-Transforming growth factor (TGF)-β is a multifunctional peptide that is important in T-cell activation and cardiovascular remodeling, both of which are important features of Kawasaki disease (KD). We postulated that variation in TGF-β signaling might be important in KD susceptibility and disease outcome. Methods and Results - We investigated genetic variation in 15 genes belonging to the TGF-β pathway in a total of 771 KD subjects of mainly European descent from the United States, the United Kingdom, Australia, and the Netherlands. We analyzed transcript abundance patterns using microarray and reverse transcriptase-polymerase chain reaction for these same genes, and measured TGF-β2 protein levels in plasma. Genetic variants in TGFB2, TGFBR2, and SMAD3 and their haplotypes were consistently and reproducibly associated with KD susceptability, coronary artery aneurysm formation, aortic root dilatation, and intravenous immunoglobulin treatment response in different cohorts. A SMAD3 ...

Cardiovascular disease is the leading cause of death in women accounting for 1 in every 4 female deaths. Pathophysiology of ischemic heart disease in women includes epicardial coronary artery, endothelial dysfunction, coronary vasospasm, plaque erosion and spontaneous coronary artery dissection. Angina is the most common presentation of stable ischemic heart disease (SIHD) in women. Risk factors for SIHD include traditional risks such as older age, obesity (body mass index [BMI] ,25 kg/m2), smoking, hypertension, dyslipidemia, cerebrovascular and peripheral vascular disease, sedentary lifestyle, family history of premature coronary artery disease, metabolic syndrome and diabetes mellitus, and nontraditional risk factors, such as gestational diabetes, insulin resistance/polycystic ovarian disease, pregnancy-induced hypertension, pre-eclampsia, eclampsia, menopause, mental stress and autoimmune diseases ...
We thank Dr. Alfonso and colleagues for their kind letter in response to our paper (1). We agree that revascularization for patients with spontaneous coronary artery dissection (SCAD) is challenging and often terminates with suboptimal results, and thus we have adhered to a conservative approach unless patients have ongoing or recurrent ischemia. Indeed, repeat angiography in a subset of patients treated conservatively invariably demonstrated spontaneous healing of dissections (1). Our cohort included all nonatherosclerotic SCAD cases identified and evaluated in our center (no patient was excluded). We recently reported good long-term outcomes in our expanded cohort of 86 SCAD patients at the 2013 American College of Cardiology meeting, despite our low revascularization rate (2). Our results, together with your reported cohort of 45 SCAD patients in Spain (3), confirm that the natural history of SCAD is such that the vast majority heals spontaneously. Thus, clinicians should avoid intervention ...

OBJECTIVES: To determine whether coronary artery lesions (ectasia and aneurysm) are commonly observed on the initial echocardiogram of patients with acute Kawasaki syndrome, whether coronary artery ectasia and/or aneurysms occur more frequently in patients with incomplete Kawasaki syndrome than in those patients with complete findings, and whether earlier diagnosis and treatment of Kawasaki syndrome are associated with less frequent occurrence of coronary artery ectasia and/or aneurysm.. DESIGN: A retrospective medical record review.. SETTING: A tertiary care pediatric hospital.. PARTICIPANTS: One hundred patients treated for Kawasaki syndrome between July 1, 1998, and June 30, 2003, who were identified by a medical record search.. MAIN OUTCOME MEASURE: Prevalence of coronary artery lesions (ectasia and aneurysm) on the initial and subsequent echocardiograms.. RESULTS: Forty-four percent of patients had a coronary artery lesion (31% with ectasia, 13% with aneurysm) on the initial echocardiogram. ...
Author(s): Shimizu, Chisato; Sood, Alka; Lau, Hubert D; Oharaseki, Toshiaki; Takahashi, Kei; Krous, Henry F; Campman, Steven; Burns, Jane C | Abstract: Coronary artery aneurysms (CAA) may remain silent after Kawasaki disease (KD) until adulthood when myocardial ischemia can lead to sudden death. We postulated that there would be young adults with sudden, unexpected death due to CAA from KD who would have a state-mandated autopsy performed by the San Diego County Medical Examiners Office (SDCMEO).We reviewed all autopsy cases <35years of age from 1997 to 2012 at the SDCMEO with a cardiovascular cause of death (n=154).We found 2 cases meeting inclusion criteria. Case 1 was a 22-year-old Korean male with chronic ischemic changes due to a partially occluded and diffusely calcified 15mm aneurysm at the bifurcation of the left main coronary artery. Interview of the mother revealed that this patient had been diagnosed with KD complicated by giant aneurysms at age two years. Case 2 was a 30-year-old
A clinically significant cardiac injury occurs in 5% to 15% of patients with severe blunt chest trauma [1, 2, 3, 4]. Coronary artery dissection has a very low incidence. Coronary artery dissection due to blunt chest trauma is even less common and a life-threatening complication [5]. A traumatic dissection is most commonly seen in the LAD (76%), followed by the RCA (12%) and circumflex artery (6%) [6]. The mechanism is poorly understood, but the vulnerable anatomic position of the heart is probably the explanation why the LAD is most affected. The RCA is likely to be most vulnerable at its origin due to acceleration/deceleration injuries [7].. Christensen et al. reviewed 76 published cases of post-traumatic myocardial infarctions [8]. In almost 90% of the cases, the myocardial infarctions were due to motor vehicle collisions or high-velocity trauma. In about 70% of these cases, the infarction was caused by occlusion or dissection of a coronary artery. The presentation or recognition of a ...
8 mm). Saccular and fusiform aneurysms usually develop between 18 and 25 days after the onset of illness. Even when treated with high-dose IVIG regimens within the first 10 days of illness, 5% of children with Kawasaki disease develop at the least transient coronary artery dilation and 1% develop giant aneurysms. Death can occur due either to myocardial infarction secondary to blood clot formation in a coronary artery aneurysm or to rupture of a large coronary artery aneurysm. Death is most common two to 12 weeks after the onset of illness. Many risk factors predicting coronary artery aneurysms have been identified, including persistent fever after IVIG therapy, low hemoglobin concentrations, low albumin concentrations, high white-blood-cell count, high band count, high CRP concentrations, male sex, and age less than one year. Coronary artery lesions resulting from Kawasaki disease change dynamically with time. Resolution one to two years after the onset of the disease has been observed in half ...

Catheter-based angiography versus CT angiography for the diagnosis of extracoronary fibromuscular dysplasia in patients with spontaneous coronary artery dissection
BACKGROUND: Myocardial fibrosis and perfusion abnormalities can occur in patients with Kawasaki disease (KD). We explored using the new three-dimensional speckle tracking echocardiography (3DSTE) the left ventricular (LV) mechanics in adolescents and young adults with a history of KD.. METHODS: Twenty-five KD patients (18 males) aged 17.0 ± 5.2 years, 14 with (group I) and 11 without (group II) coronary aneurysms, were studied. The 3D volume datasets were acquired for quantification of LV global 3D strain, global and regional area strain, systolic dyssynchrony index (SDI), twist, twist gradient (twist/LV length), and ejection fraction.. RESULTS: The results were compared with those of 14 age-matched controls. Of the 14 group I patients, 6 had left, 2 had right, and 6 had both left and right coronary aneurysms. Compared with controls, group I patients had significantly lower LV systolic global 3D strain (43.7 ± 7.3% vs. 50.4 ± 6.6%, P = 0.02), twist (8.7 ± 1.3° vs. 11.4 ± 2.0°, P , 0.001), ...

AU - Movahed, Mohammad Reza. PY - 2020/7/1. Y1 - 2020/7/1. N2 - In this report, we describe a case of spontaneous coronary dissection involving left anterior descending artery presenting with acute anterior myocardial infarction successfully treated with thrombolytic and conservative therapy with a suggestion that spontaneous resolution of thrombus occurred before coronary intervention could be performed. As we did not have initial angiogram due to patients refusal, this assumption is speculative. However, this case suggests that dissections may heal spontaneously and could be treated with conservative approach in selected cases based on best clinical judgment. It is important to realize that the clinical course of a major coronary artery dissection remains unpredictable. Therefore, cardiologists ...

Kawasaki Disease (KD) is a potentially fatal vasculitis of young childhood. Although the initial presenting symptoms of fever, exanthem, enanthem, conjunctival injection, extremity changes, and adenopathy are self-limiting, our recent seminal pathologic study of autopsy or surgical arterial tissues from 41 KD patients demonstrated subacute/chronic vasculitis persisting for months to years after the onset in these patients with severe coronary artery disease. Chronic KD vasculitis was not recognized in early pathologic studies of KD, and children with persistent coronary artery aneurysms do not receive additional immunomodulatory therapies after the acute febrile phase of illness. We hypothesize that prolonged immune activation contributes to persistent coronary arteritis in KD patients, and that markers of immune activation can be detected in the sera of KD children with persistent coronary artery aneurysms. In preliminary studies, we demonstrated upregulation of more than 20 immune response ...
Kawasaki disease is a leading cause of acquired heart disease among children in the United States and other developed countries. Most children who contract this illness are less than two years old, and 80 percent of affected children are younger than five years of age. A generalized vasculitis of unknown etiology, Kawasaki disease can cause coronary artery abnormalities, including coronary aneurysms. From 20 to 25 percent of untreated children develop coronary artery abnormalities, which may resolve or persist. These abnormalities are of particular concern because they can lead to thrombosis, evolve into segmental stenosis or, rarely, rupture. The principal cause of death from Kawasaki disease is myocardial infarction. The cause of the disease remains unknown, but epidemiologic investigations and the clinical presentation suggest a microbial agent. Diagnostic criteria, including fever and other principal features, have been established. In the acute phase of the disease, treatment with acetylsalicylic
Abstract Background: Kawasaki disease is one of the leading causes of acquired heart disease in children. It is an acute self-limited vasculitis that predominantly affects infants and children younger than 5 years of age. These patients present with nonspecific symptoms, such as fever and lymphadenopathy, making the diagnosis challenging. This disease can have serious and potentially fatal outcomes, and prompt recognition of this disease is vital to the patients outcome. We present a complete review of the disease, including the epidemiology, pathophysiology, diagnosis and management of acute Kawasaki disease, the natural history of this disease, and follow up of these patients as they transition into the adult cardiology practice. Methods: Our systematic review information were collected from articles retrieved from PubMed library. Keywords that were used included; Kawasaki disease, coronary artery disease, coronary artery aneurysm, pediatric coronary artery disease, epidemiology of Kawasaki disease

BACKGROUND:. Kawasaki Disease (KD) is an inflammatory vasculitis of unknown etiology that affects infants and children and can cause coronary artery aneurysms. Standard therapy consists of 2 gm/kg of intravenous immune globulin plus high-dose aspirin in the acute phase, and low-dose aspirin in the convalescent phase. Some children do not respond to this therapy, and some children go on to develop coronary artery aneurysms in spite of aggressive treatment. This led to the design of this randomized controlled trial to compare a single dose of intravenous steroids vs. placebo on the background of standard therapy. Recruitment began in December, 2002 and ended in December, 2004 with nearly 200 patients randomized.. DESIGN NARRATIVE:. This is a randomized controlled trial to compare a single dose of intravenous steroids vs. placebo on the background of standard therapy ...

Without treatment, about 1 in 5 children who have Kawasaki disease develop inflammation of the blood vessels to the heart (coronary arteries). This can cause a swelling of a section of an artery, which is called an aneurysm.. A coronary artery aneurysm usually causes no symptoms. Over time it often goes away and the artery returns to normal. However, the wall of an aneurysm is weakened and abnormal. Serious problems may develop in some children with an aneurysm. The most serious is that a clot (thrombosis) may develop in the aneurysm. The muscle of the heart is supplied with oxygen, carried in the blood of these arteries. If a clot develops, the muscle does not get enough oxygen. The heart muscle can then be damaged, causing a heart attack. Currently less than 1 in 100 children with Kawasaki disease die of heart problems.. An aneurysm can be detected by a heart scan (an echocardiogram). If an aneurysm does occur, it starts to develop a week or more after the fever and other acute symptoms begin. ...
Kawasaki disease during pregnancy - What is the definition or description of: Kawasaki disease? Kawasaki disease. Kawasaki disease is a rare disease of the blood vessels. Symptoms included fever > 5 days, red eyes, swollen red hands and feet, swollen red cracked lips and tongue, swollen neck lymph nodes and body rash. Kawasaki disease can also seriously affect the coronary heart vessels and gallbladder. It most commonly affects children under 8 years old. Cause of Kawasaki disease is unknown.

ABSTRACT During the COVID-19 pandemic, a new, severe and unusual condition called Multisystem Inflammatory Syndrome in children emerged, from which there is still much to learn. We report 8 children admitted to Instituto Nacional de Salud del Niño, in Lima, Perú. Their mean age was 5,1 years. Their clinical presentation included fever, acute gastrointestinal symptoms, ocular and mucocutaneous involvement. Four patients met criteria for classic Kawasaki Disease. All the patients had positive serology for SARS-CoV-2, abnormal complete blood counts and coagulation tests, and elevated inflammatory markers. Five had elevated liver enzymes and three had kidney involvement. Four patients met criteria for Macrophage Activation Syndrome. All of them received intravenous immune globulin, corticosteroids and aspirin. No coronary aneurysms were identified. Only one developed miocarditis, shock and was admitted to the Pediatric Intensive Care Unit. Most patients recovered successfully. Every child with ...
TOKYO/NEW YORK - One of the top priorities in the fight against the coronavirus is to understand how, exactly, the pathogen attacks and kills.. The virus enters through the respiratory system. But it has also been found to cause complications in other parts of the body, such as the heart and kidneys, after it makes its way through the blood stream.. Earlier this month, New York State Gov. Andrew Cuomo raised alarm about another possible risk from the coronavirus - an inflammatory syndrome that entails similar symptoms to Kawasaki disease.. Is the new syndrome actually Kawasaki disease? Is there a cure? Here are six things to know.. What is Kawasaki disease?. Kawasaki disease is an acute inflammatory illness that affects blood vessels throughout the body. Children under age 5 are considered the most at risk, and it is more common in Asia and among individuals of Asian ancestry. The cause is unknown.. In Japan, 10,000 to 15,000 cases are reported annually.. Cardiac aneurysms are the most dangerous ...
Shupyk National Medical Academy of Postgraduate Education, Kiev, Ukraine The article describes the modern views on the epidemiology, etiopathogenesis, clinical picture, diagnosis and treatment of Kawasaki disease. Kawasaki disease is a systemic disease with an acute course, which occurs mainly in children up to 5 years. The clinical pattern of disease resembles an infectious process, but on the basis of morphological changes it is referred to vasculitides, mainly affecting the blood vessels of medium caliber, and most often the coronary vessels. Kawasaki disease is a clinical diagnosis. The infusion of intravenous human immunoglobulin is using in treatment of the pathology. Key words: Kawasaki Disease, children, adolescents, epidemiology, pathogenesis, clinic, diagnostics, treatment. References 1. Berezhnyi VV, Herman OB. (2015). Khvoroba Takaiasu.

The risk of coronary artery lesions (CALs) in Kawasaki disease (KD) is related to CYP2E1 gene polymorphisms, a study from Taiwan confirmed.
Kawasaki disease, the leading cause of acquired heart disease in children in the United States, is characterized by inflammation of blood vessels throughout the body, especially the coronary arteries around the heart. The disease is most common in children under 5 years of age, occurs more often in boys than in girls, and is more prevalent during the winter and spring months.. Each year, there are roughly 2000 cases of Kawasaki disease in the United States. Although the exact cause of the disease remains unknown, experts suspect that it is caused, in part, by a pathogen such as a virus or bacteria, which may explain why cases often appear in clusters. At this time there are no means of prevention, nor is there evidence that the disease is contagious.. ...
Although etiology of Kawasaki disease remains elusive, the available evidence indicates that the primum movens might be a dysregulation of immune responses to various microbes, i.e. a kind of immune-mediated response induced by a viral infection. Even if several data might suggest that Kawasaki disease is an infection-related clinical syndrome, which can develop only in children with a predisposing genetic background, our knowledge on both the infectious agents involved and the genetic characteristics of children prone to the disease remains poor.
