Animal experimental implantation of an atrial septal defect occluder system. (1/768)

OBJECTIVE: To establish the implantation technique for the atrial septal defect occluder system (ASDOS) device in an experimental animal model and to determine long term mechanical stability of the device and its in vivo properties in terms of biocompatibility and tissue reaction. MATERIALS AND METHODS: An atrial septal defect was created and the device implanted in 17 pigs (mean weight 30 kg). The implantation technique was refined and modified because of initial technical and anatomical complications during nine acute pilot studies. The technique proved to be feasible in eight subsequent survival studies. Four pigs were electively killed three months after implantation (group 1). The remaining four pigs were killed six months after implantation (group 2). RESULTS: Necropsy showed all devices were embedded in soft tissue three months after implantation. Microscopic examination of atrial septal tissue showed an acute granulomatous inflammatory reaction in group 1 and fibrosis in group 2. The intensity of the inflammatory reaction around the device was clearly milder in group 2, indicating a decline in the inflammatory response with time. Clinical and biochemical investigations indicated acceptable biocompatibility of the device. CONCLUSION: The implantation technique for the ASDOS device in a chronic pig model has been established. Biocompatibility of the device was acceptable.  (+info)

Prenatal features of ductus arteriosus constriction and restrictive foramen ovale in d-transposition of the great arteries. (2/768)

BACKGROUND: Although most neonates with d-transposition of the great arteries (TGA) have an uncomplicated preoperative course, some with a restrictive foramen ovale (FO), ductus arteriosus (DA) constriction, or pulmonary hypertension may be severely hypoxemic and even die shortly after birth. Our goal was to determine whether prenatal echocardiography can identify these high-risk fetuses with TGA. METHODS AND RESULTS: We reviewed the prenatal and postnatal echocardiograms and outcomes of 16 fetuses with TGA/intact ventricular septum or small ventricular septal defect. Of the 16 fetuses, 6 prenatally had an abnormal FO (fixed position, flat, and/or redundant septum primum). Five of the 6 had restrictive FO at birth. Five fetuses had DA narrowing at the pulmonary artery end in utero, and 6 had a small DA (diameter z score of <-2.0). Of 4 fetuses with the most diminutive DA, 2 also had an abnormal appearance of the FO, and both died immediately after birth. One other fetus had persistent pulmonary hypertension. Eight fetuses had abnormal Doppler flow pattern in the DA (continuous high-velocity flow, n=1; retrograde diastolic flow, n=7). CONCLUSIONS: Abnormal features of the FO, DA, or both are present in fetuses with TGA at high risk for postnatal hypoxemia. These features may result from the abnormal intrauterine hemodynamics in TGA. A combination of restrictive FO and DA constriction in TGA may be associated with early neonatal death.  (+info)

Anatomical study of truncus arteriousus communis with embryological and surgical considerations. (3/768)

Twelve specimens of truncus arteriosus communis have been studied anatomically, with special reference to the conal anatomy and to the associated cardiac anomalies which can create additional problems if surgical repair is planned. A wide spectrum of conal morphology has been observed, suggesting that differential conal absorption is a developmental characteristic of truncus arteriousus as well as of transposition complexes. The invariable absence of septation of the ventricular infundibula and semilunar valves, in spite of the variable anatomy of the free wall of the conus, indicates that all types of truncus arteriosus, ontogenetically, should be considered as a single undivided conotruncus. Various types of ventircular septal defect were found: (a) ventricular septal defect with absent crista, in which no remnants of conal septum are present; (b) supracristal ventricular septal defect, in which vestigial conal septum is seen in front of the membranous septum; (c) bulloventricular foramen, associated with univentricular origin of the truncus from the right ventricle. Frequent associated anomalies are underdevelopment of the aortic arch, truncal valve malformations, and obstructive ventricular septal defect. The AV conduction system studied in one case showed an arrangement similar to Fallot's tetralogy with the His bundle and the left bundle-branch in a safe position behind the posteroinferior rim of the defect. The postoperative fate of the frequently abnormal truncal valve and the theoretical indications for total repair for Type IV truncus are also discussed.  (+info)

Echocardiographic examination of cardiac structure and function in elite cross trained male and female Alpine skiers. (4/768)

OBJECTIVE: To assess cardiac structure and function in elite cross-trained male and female athletes (Alpine skiers). METHODS: Sixteen athletes (10 male, six female) and 19 healthy sedentary control subjects (12 male, seven female) volunteered to take part in the study. Basic anthropometry determined height, body mass, body surface area, and fat free mass. Cardiac dimensions and function were determined by two dimensional, M mode, and Doppler echocardiography. Absolute data and data corrected for body size (allometrically determined) were compared by two way analysis of variance and post hoc Scheffe tests. RESULTS: Absolute left ventricular internal dimension in diastole (LVIDd), septal and posterior wall thickness and left ventricular mass were larger in athletes than controls (p < 0.05) and also increased in the men (p < 0.05) compared with women (except for septal thickness in controls). An increased LVIDd, septal thickness, posterior wall thickness, and left ventricular mass in athletes persisted after correction for body size except when LVIDd was scaled by fat free mass. Cardiac dimensions did not differ between the sexes after correction for body size. All functional indices were similar between groups. CONCLUSION: There is evidence of both left ventricular chamber dilatation and wall enlargement in cross trained athletes compared with controls. Differences in absolute cardiac dimensions between the sexes were primarily due to greater body dimensions in the men.  (+info)

Frequency of atrial septal aneurysms in patients with cerebral ischemic events. (5/768)

BACKGROUND: Atrial septal aneurysm (ASA) is a putative risk factor for cardioembolism. However, the frequency of ASA in the general population has not been adequately determined. Therefore, the frequency in patients with cerebral ischemic events, compared with the frequency in the general population, is poorly defined. We sought to determine the frequency of ASA in the general population and to compare the frequency of ASA in patients with cerebral ischemic events with the frequency in the general population. METHODS AND RESULTS: The frequency of ASA in the population was determined in 363 subjects, a sample of the participants in the Stroke Prevention: Assessment of Risk in a Community study (control subjects), and was compared with the frequency in 355 age- and sex-matched patients undergoing transesophageal echocardiography in search of a cardiac source of embolism after a focal cerebral ischemic event. The proportion with ASA was 7.9% in patients versus 2.2% in control subjects (P=0.002; odds ratio of ASA, 3.65; 95% CI, 1.64 to 8.13, in patients versus control subjects). Patent foramen ovale (PFO) was detected with contrast injections in 56% of subjects with ASA. The presence of ASA predicted the presence of PFO (odds ratio of PFO, 4.57; 95% CI, 2.18 to 9.57, in subjects with versus those without ASA). In 86% of subjects with ASA and cerebral ischemia, transesophageal echocardiography did not detect an alternative source of cardioembolism other than an associated PFO. CONCLUSIONS: The prevalence of ASA based on this population-based study is 2.2%. The frequency of ASA is relatively higher in patients evaluated with transesophageal echocardiography after a cerebral ischemic event. ASA is frequently associated with PFO, suggesting paradoxical embolism as a mechanism of cardioembolism. In patients with cerebral ischemia and ASA, ASA (with or without PFO) commonly is the only potential cardioembolic source detected with transesophageal echocardiography.  (+info)

Significance of late diastolic potential preceding Purkinje potential in verapamil-sensitive idiopathic left ventricular tachycardia. (6/768)

BACKGROUND: Verapamil-sensitive idiopathic left ventricular tachycardia (VT) is due to reentry with an excitable gap. A late diastolic potential (LDP) is recorded during endocardial mapping of this VT, but its relation to the reentry circuit and significance in radiofrequency (RF) ablation remain to be elucidated. METHODS AND RESULTS: Sixteen consecutive patients with this specific VT were studied (12 men and 4 women; mean age, 32 years). In all patients, sustained VT was induced and during left ventricular endocardial mapping, LDP preceding Purkinje potential (PP) was recorded at the basal (11 patients), middle (3 patients), or apical septum (2 patients). The area with LDP recording was confined to a small region (0.5 to 1.0 cm2) in each patient and was included in the area where PP was recorded (2 to 3 cm2). The relative activation times of LDP, PP, and local ventricular potential (V) at the LDP recording site to the onset of QRS complex were -50.4+/-18.9, -15.2+/-9.6, and 3.0+/-13.3 ms, respectively. The earliest ventricular activation site during VT was identified at the posteroapical septum and was more apical in the septum than the region with LDP in every patient. In 9 patients, VT entrainment was done by pacing from the right ventricular outflow tract while recording LDP. During entrainment, LDP was orthodromically captured, and as the pacing rate was increased, the LDP-to-PP interval was prolonged, whereas stimulus-to-LDP and PP-to-V interval were constant. In 3 patients, the pressure applied to the catheter tip at the LDP region resulted in conduction block between LDP and PP and in VT termination. RF energy application at the LDP recording site successfully eliminated VT. CONCLUSIONS: LDP was suggested to represent the excitation at the entrance to the specialized area with a conduction delay in response to the increase in the rate within the critical slow conduction zone participating in the reentry circuit of this VT. LDP can be a useful marker for successful RF ablation for this VT.  (+info)

Regional contributions of Kv1.4, Kv4.2, and Kv4.3 to transient outward K+ current in rat ventricle. (7/768)

The aim of the present study was to assess differences in transient outward potassium current (Ito) between the right ventricular free wall and the interventricular septum of the adult rat ventricle and to evaluate the relative contributions of Kv4.2, Kv4.3, and Kv1.4 to Ito in these regions. The results show that Ito is composed of both rapidly and slowly recovering components in the right wall and septum. The fast component had a significantly higher density in the right free wall than in the septum, whereas the slow component did not differ between the two sites. Kv4.2 mRNA and protein levels were also highest in the right wall and correlated with Ito density, whereas Kv4.3 was expressed uniformly in these regions. The kinetics of the rapidly recovering component of Ito in myocytes was similar to that recorded in tsa-201 cells expressing Kv4.2 and Kv4.3 channels. Kv1.4 mRNA and protein expression correlated well with the density of the slowly recovering Ito, whereas the recovery kinetics of the slow component were identical to Kv1.4 expressed in tsa-201 cells. In conclusion, expression of Kv1.4, Kv4.2, and Kv4.3 differs between regions in rat hearts. Regionally specific differences in the genetic composition of Ito can account for the region-specific properties of this current.  (+info)

Comparison of dual-chamber pacing versus septal myectomy for the treatment of patients with hypertrophic obstructive cardiomyopathy: a comparison of objective hemodynamic and exercise end points. (8/768)

OBJECTIVES: The purpose of this study was to compare the treatment effects of septal myectomy with dual-chamber pacing in patients with hypertrophic obstructive cardiomyopathy (HOCM). BACKGROUND: The optimal treatment for symptomatic patients with drug-refractory HOCM is unknown. Both dual-chamber pacing and surgical myectomy may result in subjective symptom improvement. However, no direct comparisons with objective end points have been reported. METHODS: Thirty-nine patients with symptomatic HOCM were analyzed in this concurrent cohort study. Twenty patients underwent surgical myectomy, and 19 received dual-chamber pacemakers based on patient preference. These patients had prospective baseline and follow-up evaluations including physician assessment, echocardiography and standardized metabolic treadmill exercise testing. RESULTS: Baseline symptom status, left ventricular outflow tract gradients, exercise times and maximal oxygen consumption peak were similar between the two groups. Left ventricular outflow gradient was reduced from 76+/-57 to 9+/-17 mm Hg (p = 0.0001) after myectomy, and from 77+/-61 to 55+/-39 mm Hg (p = 0.07) after pacing (p = 0.02 for comparison with myectomy). Ninety percent of myectomy patients experienced symptomatic improvement as compared with 47% in the pacing group. Exercise duration increased significantly from 6.6+/-2.8 to 8.7+/-3.0 min (p = 0.0003) after myectomy compared with a change from 6.4+/-2.1 to 7.0+/-2.2 min (p = NS) in the pacing group. Maximal oxygen consumption increased from 19.4+/-6.4 to 22.2+/-6.5 ml/kg/min after myectomy (p = 0.004), whereas the pacing group did not experience any significant change (19.6+/-6.5 vs. 20.1+/-6.5 ml/kg/min, p = NS). CONCLUSIONS: Surgical myectomy and dual-chamber pacing improve subjective measures of functional status in patients with symptomatic HOCM. In this nonrandomized study, myectomy offered greater reduction in left ventricular outflow tract gradients and larger improvements in objective measures of patient symptoms and functional status when compared with dual-chamber pacing.  (+info)

Decreased expression of tumor necrosis factor-α and regression of hypertrophy after nonsurgical septal reduction therapy for patients with hypertrophic obstructive cardiomyopathy Academic Article ...
Also called hypertrophic cardiomyopathy, asymmetric septal hypertrophy is a condition that occurs when heart muscles cells enlarge, causing the walls of the lower heart chambers (typically the left ventricle) to become thick and stiff. This makes it difficult for the heart to relax and for a sufficient amount of blood to fill the heart chambers. While the heart squeezes normally, the limited filling prevents the heart from pumping enough blood, especially during physical activity. Children with asymmetric septal hypertrophy are not allowed to play competitive sports because of the possibility of a sudden collapse or increased heart failure.. ...

In order to evaluate the ability of the echocardiogram to detect and localize left main or left anterior descending (LAD) coronary artery lesions, 43 patients were studied. The systolic excursion of the left side of the septum and the ratio of posterior wall to septal excursion were measured. Seventeen patients had no LAD lesions; all had systolic septal excursion of 3 mm or greater. Twelve patients with septal excursion of 2 mm or less all had left main or LAD lesions, but 14 other patients with LAD lesions had septal excursions of 3 mm or greater. Nine of 16 patients with LAD lesions proximal to the first septal branch had reduced or absent septal excursion, as did three of ten with LAD lesions distal to the first septal branch. In a setting of coronary artery disease reduced or absent septal motion on echocardiography suggests involvement of the left main or left anterior descending coronary. However, the technique is relatively insensitive, with 54% of the LAD patients having normal septal ...

The embryological aetiology of LASP is incomplete fusion of the septum primum and septum secundum during the closure of foramen ovale. Fusion limited to the caudal portion of the zone of overlap leads to creation of the LASP.1 Mazur et al reported the presence of LASP in 40.8% of 294 healthy adult hearts in postmortem examination. The mean volume of the LASP was 0.31±0.11 mL, which makes up only 13.6%±9.4% (range: 3.1%-44.9%) of the appendage, and the average depth of the LASP was 8.4±5.1 mm.2 Hence, the LASP is a relatively small structure. However, in our case, the depth of LASP with a giant flap spreading to LA cavity (the white arrows in figure 1) was 30 mm. As the LASP cavity is surrounded by transverse muscle, it was difficult to insert catheters from the septal wall and isolate the right pulmonary veins. We consider that (1) the presence of LASP may also cause blood stasis in the LASP cavity, increasing the risk of blood clots formation and potentially lead to ischaemic stroke,3 (2) ...

Photos: I got my septum pierced about 4 days ago and immediately after the ring was put in, I noticed that it was noticeably off center. I mentioned this to the piercer and he said its a blind piercing so theres no guarantees it will always be straight and he also said everyones nose is built differently and my nose/septum might be the reason it looks off center. He recommended I train it by gently moving

Introduction: Hypertrophic Obstructive Cardiomyopathy (HOCM) is associated with systolic anterior motion of the mitral valve, frequently leading to mitral regurgitation (MR). We hypothesized that after septal reduction with alcohol septal ablation (ASA), left ventricular outflow tract gradients would be reduced and mitral regurgitation would improve.. Methods: We reviewed echocardiograms at baseline and 3 month post ASA for 210 consecutive patients treated at the Medical University of South Carolina between 2000 and 2007 for whom complete echo data was available. For each echocardiogram the left atrial end-systolic volume index (LAESVI), resting left ventricular outflow tract (LVOT) gradient, degree of mitral regurgitation and mitral regurgitation jet area were assessed.. Results: Mitral regurgitation was seen in 70% of patients at baseline (Figure 1A). ASA significantly reduced regurgitation, with only 41% having mild or greater MR at three months (70% vs 41%, p=,0.001), and nearly eliminated ...
Although it is often considered a disease of the young, hypertrophic obstructive cardiomyopathy is commonly diagnosed in the elderly. Studies have also indicated that this condition may be more common in older patients than is generally recognised, supporting the notion that the elderly may be a large and neglected subset of patients with hypertrophic obstructive cardiomyopathy. Whiting and colleagues35 reported that 32% of patients presenting with hypertrophic cardiomyopathy were , 60 years of age, and in a community hospital based series published by Petrin and Tavel,36 83% of patients were , 50 years of age. Krasnow and Stein37 described 23 new cases of hypertrophic cardiomyopathy with 20 of the patients over the age of 50 years and 15 of these patients over the age of 60 years. Likewise, in a study by Lever and colleagues27 hypertrophic cardiomyopathy was more commonly diagnosed in patients ⩾ 65 years of age than in those , 40 years of age. Nevertheless, most information about the ...
The short-term results of PTSMA are excellent for the reduction of LVOT obstruction (13,17,32). Previous studies report that mean resting PGs significantly reduced from 60 mm Hg to 14 mm Hg after PTSMA (13,17,32), and other studies with longer follow-up (16,18,33)do not show any recurrence of obstruction over time. One- to two-year follow-up shows continued improvement in symptoms with a mean increase of over one NYHA functional class (16,18,33). More importantly, objective tests show increases of exercise time around 40% over follow-up (18). Recently, Lakkis et al. (18)reported results of a one-year follow-up study in 50 patients. In his study, resting PGs dropped significantly from average 74 ± 23 mm Hg to 6 ± 18 mm Hg, and dobutamine-induced gradient decreased from 84 ± 28 mm Hg to 30 ± 33 mm Hg. The exercise duration increased by 2 min at one year. Similar results were also found in our study, with both resting and provokable PGs significantly reduced immediately after the PTSMA and ...

Intestinal angina is characterized by recurrent postprandial abdominal pain and anorexia. Commonly, these symptoms are caused by severe stenosis of at least two vessels among the celiac and mesenteric arteries. However, intestinal perfusion is affected not only by the degree of arterial stenosis but also by systemic perfusion. We experienced a unique case of intestinal angina caused by relatively mild stenosis of the abdominal arteries complicated with hypertrophic obstructive cardiomyopathy. We report an 86-year old Japanese man with hypertrophic obstructive cardiomyopathy and advanced atrioventricular block who was diagnosed with intestinal angina. Computed tomography showed mild stenosis of the celiac artery and severe stenosis of the inferior mesenteric artery, and these lesions were relatively mild compared with other reports. A dual-chamber pacemaker with right ventricular apical pacing was implanted to improve the obstruction of the left ventricular outflow tract. After implantation, the patient
Implantation of dual chamber pacemakers for symptoms associated with hypertrophic obstructive cardiomyopathy is being evaluated as an alternative treatment. The effectiveness of this intervention involves programming pacemaker parameters specific to the individual patient. We present a case of a patient diagnosed with hypertrophic obstructive cardiomyopathy who underwent dual chamber pacemaker implantation for symptoms refractory to medical therapy. ...
IVS hypertrophy can occur as part of generalized LV hypertrophy, or it can occur in isolation, such as in asymmetric septal hypertrophy (ASH).5 In ASH, the ratio of the IVS thickness to the inferolateral (posterior) wall thickness is ,1.3. Although ASH is a characteristic feature of hypertrophic cardiomyopathy, it can also occur in the elderly due to hypertension or aortic stenosis. Excessive thickening can lead to LVOT obstruction in systole: this condition is termed hypertrophic obstructive cardiomyopathy.5 This obstruction can be further worsened with concomitant systolic anterior motion of the anterior leaflet of the mitral valve.. Surgical repair of hypertrophic cardiomyopathy with septal myectomy is generally performed for patients with severe LVOT obstruction: a gradient at rest ,30 mm Hg, IVS thickness ,18 mm, and evidence of systolic anterior motion.6 During septal myectomy, TEE can be used to evaluate the extent of resection required, determine the presence and severity of mitral ...

Alcohol septal reduction in hypertrophic obstructive cardiomyopathy (HOCM) is indicated for patients with drug refractory symptoms or drug intolerance who have significant left ventricular obstruction.(1) On the other hand, several structural and functional changes including low-normal left ventricular (LV) ejection fraction, moderate to severe diastolic dysfunction, marked atrial dilatation, thinning of the LV walls, onset of atrial fibrillation, spontaneous reduction or loss of LV outflow obstruction, and LV apical aneurysms characterise an advanced stage of progression in the physical history of the disease which signifies adverse remodelling and clinical deterioration.(2) The benefit derived from septal reduction treatments in this stage is largely ...

Twenty-two patients with hypertrophic obstructive cardiomyopathy were treated with the calcium inhibitor, verapamil, which was administered in a mean oral dose of 480 mg per day. After an average of 15 months of treatment (4 to 24 months), the QRS amplitude in the electrocardiogram was significantly reduced from 4.2 to 3.8 mV. Heart volume calculated from chest x-ray films in the supine position decreased significantly from 858 to 766 ml per 1.73 m2. In 10 patients, follow-up heart catheterisation showed a decrease in left ventricular muscle mass in 7 patients and a slight increase in 3 patients. Coronary artery diameter decreased in 7 patients, increased in 1, and was unchanged in 2. The reduction in coronary artery diameter is considered to be a consequence of a reduced heart muscle mass. From all available clinical data it is concluded that verapamil treatment is superior to beta-blocker therapy. ...

The majority of atrial septostomies are performed on infants with d-TGA or other cyanotic heart defects. In these cases, a balloon catheter is guided through a large vein into the right atrium, during cardiac catheterization. The catheter is threaded into the foramen ovale, a naturally existing hole between the atria that normally closes shortly after birth. The balloon at the end of the catheter is inflated so as to enlarge the foramen ovale enough that it will no longer become sealed. This allows more oxygenated blood to enter the right heart (especially in the case of d-TGA) where it can be pumped to the rest of the body. The balloon is deflated and the catheter is removed. Sometimes the initial surgery is not entirely successful, or there are other factors that make a simple balloon atrial septostomy impossible, such as an older patient whose foramen ovale has already closed. This is when a blade atrial septostomy is performed. The details of the procedure are largely the same, except that a ...

Septal myectomy at Loyola Medicine is an open heart procedure used to treat hypertrophic cardiomyopathy, a genetic heart disorder that reduces blood circulation.
Septal myectomy is a type of open-heart surgery. Its done to treat hypertrophic cardiomyopathy. This is when part of the heart muscle becomes thick. The surgery helps lessen symptoms of the condition.
atrial septation - Term describing the complex developmental formation of the interatrial septum, the wall between the right and left atria of the heart. In humans, this septation process begins in week 5 of development with the septum primum, a membranous extension on the dorso-cranial wall growing downward towards endocardial cushions. An opening remains as the foramen primum (ostium primum). The septum primum fuses with endocardial cushion, but cranially had begun to degenerate forming foramen secundum (ostium secundum). A later forming septum secundum on the ventro-cranial wall grows downward, but does not fuse with endocardial cushion, the remaining opening is the foramen ovale. Abnormalities of this process are called Atrial Septal Defects (ASD), a group of common (1% of cardiac) congenital anomalies occurring in a number of different forms and more often in females. The process of separating the ventricles is called ventricular septation. atrial septal defect - (ASD) Heart developmental ...
Objective: To explore the transcriptomic differences between patients with hypertrophic cardiomyopathy (HCM) and controls. Patients and methods: RNA was extracted from cardiac tissue flash frozen at therapeutic surgical septal myectomy for 106 patients with HCM and 39 healthy donor hearts. Expression profiling of 37,846 genes was performed using the Illumina Human HT-12v3 Expression BeadChip. All patients with HCM were genotyped for pathogenic variants causing HCM. Technical validation was performed using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot. This study was started on January 1, 1999, and final analysis was completed on April 20, 2020. Results: Overall, 22% of the transcriptome (8443 of 37,846 genes) was expressed differentially between HCM and control tissues. Analysis by genotype revealed that gene expression changes were similar among genotypic subgroups of HCM, with only 4% (1502 of 37,846) to 6% (2336 of 37,846) of the transcriptome exhibiting ...

These develop at the lower end of the truncus arteriosus. At this level there are four swellings of sub-endocardial tissue - the right and left bulbar swellings and two acessory dorsal and ventral swellings. Separation of the fused bulbar ridges forms the aortic and pulmonary vessels each containing three swellings. Growth and excavation of the swellings results in the formation of the semilunar valves. Formation of the semilunar valves is complete by the end of the 9th week ...
Emerging metabolomic tools have created the opportunity to establish metabolic signatures of myocardial injury. We applied a mass spectrometry-based metabolite profiling platform to 36 patients undergoing alcohol septal ablation treatment for hypertrophic obstructive cardiomyopathy, a human model of planned myocardial infarction (PMI). Serial blood samples were obtained before and at various intervals after PMI, with patients undergoing elective diagnostic coronary angiography and patients with spontaneous myocardial infarction (SMI) serving as negative and positive controls, respectively. We identified changes in circulating levels of metabolites participating in pyrimidine metabolism, the tricarboxylic acid cycle and its upstream contributors, and the pentose phosphate pathway. Alterations in levels of multiple metabolites were detected as early as 10 minutes after PMI in an initial derivation group and were validated in a second, independent group of PMI patients. A PMI-derived metabolic ...
Hypertrophic cardiomyopathy (HCM) was first described by Donald Teare et al. in 1957 in a series of eight patients with asymmetric septal hypertrophy.1 Later in that decade, Morrow and Braunwald described three cases of a clinical syndrome mimicking aortic stenosis, which was solved by resection of the subaortic interventricular septum.2. HCM has been reported in several countries, in individuals of both sexes with varied racial and ethnic backgrounds, with or without resting left ventricular obstruction, but with similar genotypic abnormalities. Its estimated incidence is 1 per 500 individuals in the general population (0.2%), but delay in diagnosis is common. HCM is an important public health problem due to sudden cardiac death (SCD), heart failure (HF), atrial fibrillation and ventricular arrhythmias that occur in the course of the disease.3. HCM is a monogenic disease caused by a mutation in one of the 13 or more genes encoding the protein components of the sarcomere. It has an autosomal ...
Severely symptomatic patients with obstructive hypertrophic cardiomyopathy (HC) may benefit from surgical myectomy. In patients with enlarged mitral leaflets and mitral regurgitation, myectomy can be combined with anterior mitral leaflet extension (AMLE) to stiffen the midsegment of the leaflet. The aim of this study was to evaluate the long-term results of myectomy combined with AMLE in patients with obstructive HC. This prospective, observational, single-center cohort study included 98 patients (49 ± 14 years, 37% female) who underwent myectomy combined with AMLE from 1991 to 2012. End points included all-cause mortality and change in clinical and echocardiographic characteristics. Mortality was compared with age- and gender-matched patients with nonobstructive HC and subjects from the general population. Long-term follow-up was 8.3 ± 6.1 years. There was no operative mortality, and New York Heart Association class was reduced from 2.8 ± 0.5 to 1.3 ± 0.5 (p ,0.001), left ventricular ...
Just over a month ago, I had the first part of a hybrid cardiac ablation. That turned out to be an uncomfortable procedure to recover from. It involved a surgeon inserting a device under my sternum and ablating, or burning and/or freezing, electrical receptors on the back of my heart.. The problem is atrial fibrillation. My atrial fibrillation is complicated by a genetic abnormality of my heart called hypertrophic cardiomyopathy, a.k.a. HCM, or, in my case, HOCM: hypertrophic obstructive cardiomyopathy. That means that somewhere along the line when I was growing up, instead of the heart muscles continuing to grow in a striated manner, they went myopic and began to clump. So the septum of my heart is thicker than it should be. This condition is actually pretty common, affecting about one in 500 people. However, most people never know they have it, live their lives and are never diagnosed nor in need of a diagnosis. They discovered it in me when I was running marathons and other distance races. ...

Hypertrophic cardiomyopathy can be treated by a medical procedure or medication. Medications can reduce the pumping power of the heart, stabilize the rhythm, and make your heart relaxes. If the patient is at risk were classified as serious, then cardioversion defibrillator implants can be used to reduce the problem of irregular heartbeat. Other medical action that can be done is septal myectomy, which is making the heart muscle wall (septum) which thicken to the blood flow while reducing mitral regurgitation. Moreover, it can be done ablation of the heart muscle is thickened so that supply blood to flow through the area. The procedure is called with septal ablation, using an injection of alcohol on the heart muscle that want to be destroyed ...
Catching a bus shouldnt be life-threatening. But for one 23-year-old woman, running for the bus could have cost her everything. After rushing to hop on board, she fell unconscious, leaving her arm outstretched beyond the door. Not knowing this, the driver closed the door and drove to the next stop, about two-tenths of a mile away. The passenger was shocked awake by her AICD, which she wore because of a history of hypertrophic obstructive cardiomyopathy. As she regained consciousness, she realized her forearm was still outside of the bus.

significant RV dilatation and septal bowing. On CT, the patient was confirmed to have a large PE clot burden. This case highlights how doing a quick echo can be very revealing if there is suspicion of or confirmed DVT! It can show if there is a significant PE causing cardiac strain which can explain hemodynamic instability. In image A, the apical 4-chamber view shows abnormal bulging of the RV and septum into the LV. RV size can be assessed from any window although most suggest using the apical 4-chamber view and comparing relative sizes at the level of the atrioventricular valves. The RV should normally be , 2/3 of the LV. Image B is a terrific example of septal bowing which represents abnormal interventricular septal motion. Because of the increased RV pressure in this case, the interventricular septum flattens in diastole and is best seen in the parasternal short-axis as a D-shaped left ventricle. (see arrow) In addition to those above, you can also directly visualize the clot in the ...

Partially digested food starts to arrive in the small intestine as semi-liquid chyme, one hour after it is eaten.[citation needed] The stomach is half empty after an average of 1.2 hours.[31] After four or five hours the stomach has emptied.[32] In the small intestine, the pH becomes crucial; it needs to be finely balanced in order to activate digestive enzymes. The chyme is very acidic, with a low pH, having been released from the stomach and needs to be made much more alkaline. This is achieved in the duodenum by the addition of bile from the gall bladder combined with the bicarbonate secretions from the pancreatic duct and also from secretions of bicarbonate-rich mucus from duodenal glands known as Brunner's glands. The chyme arrives in the intestines having been released from the stomach through the opening of the pyloric sphincter. The resulting alkaline fluid mix neutralises the gastric acid which would damage the lining of the intestine. The mucus component lubricates the walls of the ...

In the human female, the urethra is about 1.9 inches (4.8 cm) to 2 inches (5.1 cm) long and exits the body between the clitoris and the vagina, extending from the internal to the external urethral orifice. The meatus is located below the clitoris. It is placed behind the symphysis pubis, embedded in the anterior wall of the vagina, and its direction is obliquely downward and forward; it is slightly curved with the concavity directed forward. The proximal 2/3rds is lined by transitional epithelium cells while distal 1/3rd is lined by stratified squamous epithelium cells.[10] The urethra consists of three coats: muscular, erectile, and mucous, the muscular layer being a continuation of that of the bladder. Between the superior and inferior fascia of the urogenital diaphragm, the female urethra is surrounded by the urethral sphincter. Somatic (conscious) innervation of the external urethral sphincter is supplied by the pudendal nerve. ...

  • Separation of left and right ventricular chambers is dependent on a single structure, the interventricular septum (IVS), which has both muscular and mesenchymal components. (
  • The interventricular septum (IVS, or ventricular septum, or during development septum inferius) is the stout wall separating the ventricles, the lower chambers of the heart, from one another. (
  • The greater portion of it is thick and muscular and constitutes the muscular interventricular septum. (
  • The posterior interventricular artery, a branch of right coronary artery, supplies the posterior 1/3 of the interventricular septum. (
  • The muscular part of the interventricular septum derives from the bulboventricular flange which is developed due to differential growth of primitive ventricle and bulbous cordis. (
  • A ventricular septal defect (VSD), a hole in the interventricular septum is one of the four congenital defects of the condition of tetralogy of Fallot. (
