The main trunk of the systemic arteries.
The vein which drains the foot and leg.
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.

Anomalous origin of the left coronary artery from the pulmonary artery: natural history and normal pregnancies. (1/601)

Two female patients are described with anomalous origin of the left coronary artery arising from the pulmonary artery who sustained an anterolateral myocardial infarction in infancy. Neither patient received surgical treatment although both have lived to middle age with minimal cardiovascular problems and have had uncomplicated pregnancies. Good exercise tolerance and long term survival may be possible even without surgery for patients with this anomaly.  (+info)

Short left coronary artery trunk as a risk factor in the development of coronary atherosclerosis. Pathological study. (2/601)

The relation between the length of the main left coronary artery and the degree of atherosclerosis in its branches was studied by postmortem examination in 204 subjects aged 20 to 90 years. The findings suggest that in cases with a short main left coronary artery the atherosclerotic lesions in the anterior descending and circumflex branches appear earlier, progress faster at higher levels of severity, and lead more frequently to myocardial infarction, than in cases with a long left coronary artery trunk. In cases over the age of 50 years, where disease is expected to have developed, it was shown that the degree of atherosclerosis in the left anterior descending and circumflex branches was inversely related to the length of the main left coronary artery. The correlation coefficients were -0-527 and -0-428, respectively, and in either case a test for zero correlations was significant (P less than 0-001). The possible changes in the haemodynamic and mechanical conditions associated with the variations of the anatomical pattern of the coronary arteries and their influence in the development of atherosclerosis are discussed. It is suggested that the length of the main left coronary artery is a congenital anatomical and possibly hereditary factor influencing the rate of development of atherosclerosis in the branches of the main left coronary artery.  (+info)

Coronary artery disease with single coronary artery. (3/601)

The authors have reviewed the literature in search of the coexistence of single coronary artery with significant coronary artery disease. Two cases of single right coronary artery are described. In both, the anomalies were unsuspected and diagnosed roentgenographically in life. Both patients had angina pectoris, positive graded-exercise stress tests, and hemodynamically significant obstruction or occlusion to the coronary arteries. In neither case was the stenosis proximal or amenable to bypass surgery.  (+info)

Evolution of risk factors influencing early mortality of the arterial switch operation. (4/601)

OBJECTIVES: The present study was undertaken to determine the independent risk factors for early mortality in the current era after arterial switch operation (ASO). BACKGROUND: Prior reports on factors affecting outcome of the ASO demonstrated that abnormal coronary arterial patterns were associated with increased risk of early mortality. As diagnostic, surgical and perioperative management techniques continue to evolve, the risk factors for the ASO may have changed. METHODS: All patients who underwent the ASO at Children's Hospital, Boston between January 1, 1992 and December 31, 1996 were included. Hospital charts, echocardiographic and cardiac catheterization data and operative reports of all patients were reviewed. Demographics and preoperative, intraoperative and postoperative variables were recorded. RESULTS: Of the 223 patients included in the study (median age at ASO = 6 days and median weight = 3.5 kg), 26 patients had aortic arch obstruction or interruption, 12 had Taussig-Bing anomaly, 12 had multiple ventricular septal defects, 8 had right ventricular hypoplasia and 6 were premature. There were 16 early deaths (7%), with 3 deaths in the 109 patients considered "low risk" (2.7%). Coronary artery pattern was not associated with an increased risk of death. Compared with usual coronary anatomy pattern, however, inverted coronary patterns and single right coronary patterns were associated with increased incidence of delayed sternal closure (p = 0.003) and longer duration of mechanical ventilation (p = 0.008). In a multivariate logistic regression model using only preoperative variables, aortic arch repair at a separate procedure before ASO and smaller birth weight were independent predictors of early mortality. In a second model that included both pre- and intraoperative variables, circulatory arrest time and right ventricular hypoplasia were independent predictors of early death. CONCLUSIONS: The ASO can be performed in the current era without excess early mortality related to uncommon coronary artery patterns. Aortic arch repair before ASO, right ventricular hypoplasia, lower birth weight and longer intraoperative support continue to be independent risk factors for early mortality after the ASO.  (+info)

Unusual congenital coronary anomaly and myocardial ischaemia. (5/601)

Angiography was used to diagnose a rare congenital coronary anomaly with myocardial ischaemia in a woman with typical angina. All three coronary arteries arose from a solitary coronary ostium in the right aortic sinus; the left anterior descending coronary artery followed a septal course, the circumflex coronary artery ran behind the ascending aorta, and the right coronary artery followed a normal course. No significant coronary lumen narrowing was found. Transoesophageal echocardiography confirmed the anomalous origin and course of the aberrant coronary arteries. An exercise test reproduced angina, and ECG changes and myocardial perfusion study showed an anterior reversible defect. In contrast to previous reports, myocardial ischaemia was associated with the septal (intramuscular) course of the left anterior descending coronary artery; there was no other significant coronary artery disease.  (+info)

New signs characteristic of myocardial bridging demonstrated by intracoronary ultrasound and Doppler. (6/601)

BACKGROUND: Large discrepancies exist concerning the incidence of myocardial bridging. This has been reported to be 0.5%-2.5% following coronary angiography but 15%-85% following autopsy. The purpose of the study was to use intravascular ultrasound and intracoronary Doppler to study the morphology and flow characteristics of myocardial bridging in order to find feasible parameters of this syndrome. METHODS AND RESULTS: Intravascular ultrasound was performed in 62/69 patients in whom typical angiographic 'milking effects' were present. In 48 patients, intracoronary Doppler was performed. A specific, echolucent 'half moon' phenomenon surrounding the myocardial bridge was found in all the patients. The thickness of the half moon area was 0.47 +/- 0.19 mm in diastole and 0.52 +/- 0.23 mm in systole. There was systolic compression of the myocardial bridge with a lumen reduction during systole of 36.4 +/- 8.8%. Using intracoronary Doppler, a characteristic early diastolic 'finger tip' phenomenon was observed in 42 (87%) of the patients. All patients showed no or reduced antegrade systolic flow. Coronary flow velocity reserve was 2.03 +/- 0. 54. After intracoronary nitroglycerin injection, retrograde systolic flow occurred in 37 (77%) of the 48 patients, with a velocity of -22. 2 +/- 13.2 cm. s(-1). Intravascular ultrasound revealed atherosclerotic involvement of the proximal segment in 61 (88%) of the 69 patients, with an area stenosis of 42 +/- 13%. No plaques were found in the bridge or distal segments in the 62 patients in whom it was possible to introduce the ultrasound catheter throughout the bridging segment. CONCLUSION: Myocardial bridging is characterized by the following morphological and functional signs: a specific, echolucent half moon phenomenon over the bridge segment, which exists throughout the cardiac cycle; systolic compression of the bridge segment of the coronary artery; accelerated flow velocity at early diastole (finger-tip phenomenon); no or reduced systolic antegrade flow; decreased diastolic/systolic velocity ratio; retrograde flow in the proximal segment, which is provoked and enhanced by nitroglycerin injection.  (+info)

A 72 year old woman with ALCAPA. (7/601)

ALCAPA syndrome (anomalous origin of the left coronary artery from the pulmonary artery), which causes the left coronary artery to grow with an anomalous origin from the pulmonary artery, is a rare disease which may result in myocardial infarction, congestive heart failure, and sometimes death during the early infantile period. A 72 year old woman with ALCAPA syndrome is presented. The asymptomatic patient presented with a cardiac murmur which was discovered during a routine check up for a gynaecological intervention. Coronary cineangiography established the diagnosis. Although surgical correction is the usual treatment for such cases, medical treatment was preferred for this patient because she was asymptomatic without clinical signs of heart failure.  (+info)

Mice lacking the vascular endothelial growth factor-B gene (Vegfb) have smaller hearts, dysfunctional coronary vasculature, and impaired recovery from cardiac ischemia. (8/601)

Vascular endothelial growth factor-B (VEGF-B) is closely related to VEGF-A, an effector of blood vessel growth during development and disease and a strong candidate for angiogenic therapies. To further study the in vivo function of VEGF-B, we have generated Vegfb knockout mice (Vegfb(-/-)). Unlike Vegfa knockout mice, which die during embryogenesis, Vegfb(-/-) mice are healthy and fertile. Despite appearing overtly normal, Vegfb(-/-) hearts are reduced in size and display vascular dysfunction after coronary occlusion and impaired recovery from experimentally induced myocardial ischemia. These findings reveal a role for VEGF-B in the development or function of coronary vasculature and suggest potential clinical use in therapeutic angiogenesis.  (+info)

AU - Davis, Wesley. PY - 2010/4/1. Y1 - 2010/4/1. N2 - Anomalous right coronary artery (ARCA) from left sinus of Valsalva could present in several forms either being intramural or extramural, and most occurring with separate ostium from left coronary system. ARCA originating from the left main coronary artery (LMCA) is very rare and treatments proposed for this type of anomaly are pulmonary artery translocation or coronary artery bypass grafting (CABG) of the right coronary system. There has not been any report in the literature of successful reimplantation of ARCA from LMCA, to the best of our knowledge, as another surgical option for this anomaly. We are reporting a case of successful surgical reimplantation of an ARCA from LMCA.. AB - Anomalous right coronary artery (ARCA) from left sinus of Valsalva ...

DISCUSSION AND CONCLUSION: C-CTA is an effective method in detecting coronary artery diseases, variations and anomalies. There are studies indicating that c-CTA is superior to catheter angiography in the diagnosis of coronary artery anomalies. Coronary artery anomalies are the uncommon category of cardiac diseases. Their incidence in the community is 1-2%. Our study supports that c-CTA is an imaging method that is used in the diagnosis of coronary artery anomalies and variations and provides detailed information ...

AU - Chen, Chi Jen. AU - Mo, Yuan Heng. PY - 2007/9. Y1 - 2007/9. N2 - Anomalous coronary arteries can be benign or life threatening. Novel advances on multi-detector computed tomography (MDCT) provide a noninvasive technique and offer an accurate diagnostic modality to visualize the origin and course of anomalous coronary arteries by a 3D display of anatomy. Thus we demonstrated anomalies of coronary arteries shown by 64-MDCT in our institution. 540 subjects referred to our Hospital for MDCT coronary angiography were included in this study. These subjects were between the ages of 12 and 90 years (mean 59±12.6 years) including 297 (55%) male and 243 (45%) female. Post-processing techniques such as volume rendering (VR) and maximum intensity projection (MIP) were applied to demonstrate the coronary ...
Keywords: Anomaly, congenital anomalies, coronary artery nomalies, fistula PCI congenital anomalies, gender, PCI.. Abstract: Background: Although not well established; gender may play a role in the incidence, clinical manifestations, and atherosclerotic burden of Coronary Artery Anomalies (CAAS). Our aim is to investigate the impact of gender on coronary artery anomalies. Methods: All coronary angiograms performed at the University Heart Center Zurich, Switzerland, between January 2000 and December 2016 were investigated. Those of anomalous origin, course and termination (fistula) were included in the analysis with the exclusion of coronary artery aneurysms and myocardial bridges. Results: Out of the original 39577 angiographic studies that included 28550 males and 11026 females, Coronary Artery Anomalies (CAAS) were documented in 130 (0.32%) patients of whom 69.2% (n=90) and 30.8%(n=40) were males and females respectively. However, the overall prevalence of coronary anomalies amongst both ...
An anomalous coronary artery (ACA) is a coronary artery that has an abnormality or malformation. The malformation is congenital (present at birth) and is most often related to the origin or location of the coronary artery. However, there may be other defective areas in the coronary artery. Likewise, it may affect the overall size and shape of the affected coronary artery or arteries. ACA may also occur along with other congenital heart defects.. This condition may also be called congenital coronary artery anomaly (CAA).. Although they are present at birth, ACAs are often not diagnosed until late adolescence or adulthood, because of the lack of symptoms or because symptoms may not be recognized as being caused by ACA. Teens or adults with unknown ACA may have an initial episode of chest pain, heart failure, or even sudden cardiac death before the condition is recognized.. ...

Electron beam tomography (EBT) has been widely used for the assessment of coronary calcification, particularly in patients at risk of coronary artery disease. EB angiography (EBA) has shown significant sensitivity in confirming coronary arterial narrowing involving the proximal and mid-vessel segments. The main advantage of this new imaging technique is its ability to demonstrate the arterial tree, including the coronary arteries, using single breath-hold acquisition while infusing intravenous contrast agent. It does not require a large dose of x-ray radiation exposure followed by a long recumbency for arterial healing, as does conventional coronary angiography. EBA also avoids possible claustrophobic effects of closed tube imaging used by other noninvasive techniques. We present a new application of this technique in patients with anomalous coronary arteries. In 6 patients with congenital anomalous coronary arteries, all coronary artery origins and courses were clearly demonstrated. An example ...

Coronary anomalies are detected in about 1 % of the general population by coronary angiography and have little clinical significance (Angelini et al. 2002). However, a minority of coronary artery anomalies, particularly in which the coronary artery takes an interarterial course, are known to have a risk of myocardial ischemia or sudden cardiac death (Rigatelli et al. 2005). Several possible causes of myocardial ischemia in cases with anomalous coronary artery origin from the wrong aortic sinus with a course between the aorta and the pulmonary artery have been suggested: acute angle take-off of the coronary artery producing a slit-like lumen; closure of the abnormal coronary orifice by a valve-like ridge at aortic expansion; compression of the artery when it courses within the aortic wall (intramural course) or between the aorta and the pulmonary artery; and spasm of the anomalous coronary artery (Basso et al. 2000; Virmani et al. 1984). Virmani et al. (1984), after observing postmortem coronary ...

Coronary artery anomalies (CAAs) include congenital or acquired anomalies that may affect young athletes. Examples of congenital anomalies include anomalous aortic origin of a coronary artery (AAOCA) and anomalous origin of a coronary artery from the pulmonary artery. The main example of acquired CAAs affecting young athletes today is Kawasaki disease, an acquired inflammatory process that targets small vessels, particularly the coronary circulation. For the purpose of this discussion, the focus will be on AAOCA, reportedly the second most common cause of sudden cardiac death (SCD) in young athletes.. The occurrence of SCD generates extreme anxiety in schools, sports organizations, and communities at large, causing it to become a greater societal burden.1 Several factors of AAOCA are unknown, including the exact prevalence, the pathophysiological mechanisms leading to SCD, the actual risk of death for the different types of anatomy, the optimal way to evaluate these patients, and whether or not ...

Anomalous origination of coronary artery from the opposite sinus (ACAOS) is a rare coronary artery anomaly. Right ACAOS with interarterial course is a type of ACAOS, which conveys a high risk for myocardial ischemia or sudden death. We reported a case of right ACAOS with interarterial course in otherwise healthy young male. He was asymptomatic, until an obligatory medical check-up with treadmill test showed a sign of positive ischemic response. Further work-up revealed that he had right ACAOS with interarterial course. Watchful observation was applied to him, while strenuous physical activity and competitive sport were absolutely prohibited.
The term coronary artery anomaly refers to a wide range of congenital abnormalities involving the origin, course, and structure of epicardial coronary arteries. By definition, these abnormalities occur in less than 1% of the general population.
Electron beam computerized tomography (EBCT) during intravenous administration of contrast medium showed an anomalous origin of the left coronary artery from the pulmonary artery, sometimes known as the Bland-White-Garland syndrome. This 28-year-old woman presented with chest pain caused by progressive myocardial ischemia. In this case, a right coronary arteriogram confirmed an enlarged right coronary artery, and both the left anterior descending branch and the circumflex artery were supplied by collateral circulation. The left main artery was connected with the pulmonary trunk during the late phase of the right coronary arteriogram. These axial EBCT images (Figure⇓) were performed with 3-mm thickness and 100-ms acquisition time. Cardiac motionless images allow clear visualization of both the anomalous origin of the left main coronary trunk and enlarged right coronary artery. We can see that the left main trunk supplied the left anterior descending branch and circumflex artery.. ...

AIM. To assess the functionality of congenital coronary artery fistulas (CAFs) using adenosine stress N-13-ammonia positron emission tomography computed tomography (PET-CT).. METHODS. Congenital CAFs were incidentally detected during coronary angiography (CAG) procedures in 11 adult patients (six males and five females) with a mean age of 64.3 years (range 41-81). Patients were collected from three institutes in the Netherlands. The characteristics of the fistulas (origin, pathway and termination), multiplicity of the origins and pathways of the fistulous vessels were assessed by CAG. Five patients underwent adenosine pharmacologic stress N-13-ammonia PET-CT to assess myocardial perfusion and the functional behavior of the fistula.. RESULTS. Eleven patients with 12 CAFs, 10 unilateral and one bilateral, originating from the left anterior descending coronary artery (n = 8), right coronary artery (n = 2) and circumflex (n = 2). All fistulas were of the vascular type, terminating into either the ...

There are several potential issues that affect the treatment and diagnostic pattern of anomalous left coronary artery arising from the pulmonary artery. We report three cases of infants who presented with anomalous left coronary artery arising from the pulmonary artery with severe left ventricular dysfunction and severe mitral regurgitation along with associated anomalies. One patient had congenital lobar emphysema of the right midde lobe. Another patient had left main stem bronchus compression, collapse of basal segments of left lower lobe and panlobular emphysema in medial basal segment of right lower lobe. The third patient had cleft lip and palate. All patients underwent successful repair. The hemodynamic stability was compromised when the infant with congenital lobar emphysema had spontaneous pneumothorax after extubation and she needed an intercostal drainage. The infant with lung collapse had to be reintubated on the second day since she became hypoxic due to recollapse of the lung once the
In some cases, cardiac anatomy at autopsy after a triathlon may occasionally provide clues to the cause of death.1 Of nine athletes autopsied after a triathlon-related death, only two had cardiac anomalies that could be construed as being a primary cause of death: one with Wolff-Parkinson-White syndrome, the other with a congenital coronary artery anomaly. On the other hand, six had LVH.1. IPO is a plausible cause of triathlon death, particularly since it has been suggested as one possible mechanism in the pathophysiology of drowning.4 In contrast, due to the rarity of IPO-related deaths and lack of known history of IPO in any triathlon death, some have concluded that it is an unlikely cause of death in triathletes.10 ,22 ,23 Nevertheless, several IPO-related deaths have been reported in other settings.42-47 Fatal cases of IPO may be rare but probably under-recognised; unless an episode is witnessed and survival is sufficiently long enough to obtain adequate clinical information to make the ...
In a narrow sense, the main purpose of the PHE is to screen for injuries or medical conditions that may place an athlete at risk for safe participation. Athletes may be affected by conditions that do not have overt symptoms and that can only be detected by periodic health evaluations. One example is cardiovascular abnormalities, such as hypertrophic cardiomyopathy, arrythmogenic right ventricular cardiomyopathy or congenital coronary arteries anomalies. These are typically silent until a potentially fatal arrhythmia occurs, but may in some cases be detected through a careful cardiovascular examination.. Screening is a strategy used in a population to detect a disease in individuals without signs or symptoms of that disease. The intention is to identify pathologic conditions early, thus enabling earlier intervention and management in the hope of reducing future morbidity and mortality. Although screening may lead to an earlier diagnosis, not all screening programs have been shown to benefit the ...
BACKGROUND AND PURPOSE Congenital coronary artery fistula (CAF) is an uncommon anomaly. It can become symptomatic, associated with significant morbidity and mortality. We report our experience in percutaneous treatment of CAF. METHODS AND RESULTS Four patients with five CAFs were treated. All were symptomatic at admission. Four fistulas rose from the left anterior descending coronary artery. The fifth originated from the right coronary sinus. All drained into the pulmonary artery. Percutaneous treatment was performed using microcoils in two cases and Hydrocoils in the last two patients (three fistulas). A complete occlusion was achieved in all. There was no complication related with the procedure, and all were asymptomatic at the follow-up. CONCLUSIONS Transcatheter closure of CAFs with microcoils/Hydrocoils is feasible and safe in the anatomically suitable vessels, with low rates of complications. Percutaneous treatment with microcoils/Hydrocoils is a valid option in symptomatic patients.

BACKGROUND The transradial approach for percutaneous coronary procedures has the advantage of reduced access site complications but is associated with specific technical challenges in comparison with the transfemoral approach. Transradial procedure failures can sometimes be due to variation in radial artery anatomy. However, data describing such variations are limited. OBJECTIVE To evaluate the incidence and impact of radial artery anomalies in patients undergoing transradial coronary procedures. METHODS Retrograde radial arteriography was performed in all patients presenting for a first-time radial procedure. Patient characteristics, radial artery anatomy and procedural outcome were assessed. RESULTS 1540 consecutive patients were studied, 70.6% male, mean (SD) age 63.6 (11.1) years. The overall incidence of radial artery anomaly was 13.8% (n = 212). 108 (7.0%) patients had a high-bifurcating radial origin, 35 (2.3%) had a full radial loop, 30 (2.0%) had extreme radial artery tortuosity and 39 (2

This is a report on a child who, in the first decade of life, collapsed after effort and died suddenly. There was clinical evidence of acute myocardial ischaemia. At autopsy, a rare cause was found, viz. aberrant origin of the left coronary artery from the right sinus of Valsalva, which then coursed between the aorta and main pulmonary artery. The importance of recognising this congenital coronary artery abnormality is emphasised.
The results of our prospective study suggest that myocardial bridging of the LAD is very frequent in ABS patients, as revealed both by coronary angiography and mostly by CTA compared with controls. Myocardial bridging is usually considered a congenital coronary anomaly with no hemodynamic relevance, but it has been associated with different clinical scenarios, such as typical or atypical angina and myocardial infarction (9-13). From the pathophysiological point of view, myocardial bridging-related myocardial ischemia may be attributed to a combination of different factors: sudden tachycardia (compromising diastolic filling of coronary arteries); increased contractility; coronary spasm and systolic kinking of the coronary arteries (leading to endothelial damage, platelet activation and thrombosis, or mechanical reduction of the blood flow) (9-13).. The true prevalence of myocardial bridging is not fully known because it is usually underdiagnosed by conventional angiography. CTA should be the ...
The surgical reconstructive potential of congenital atresia is generally made after the CT Scan has been fully evaluated. The parents are advised on the potential for reconstruction, based on the degree of development of the childs middle ear, inner ear, and mastoid, as well as the position of the facial nerve and the relative absence of or deformity of the bones of hearing. The most important factor is the development of a good middle ear cavity, not necessarily the size or shapes of the bones of hearing themselves.. The ear surgeon will see and evaluate the child on a yearly basis until age four. At four, if there is a microtia, plans should have already been made by the facial plastic surgeon for reconstruction of the microtia. Coordination between the ear surgeon and the facial plastic surgeon is essential. Scarring could occur when the ear surgeon performs the initial stages. It could compromise the graft material introduced by the facial plastic surgeon.. Most surgical teams advise that ...

Blood delivered to the coronaries in ASCAPA originates from the pulmonary artery, explaining its reduced oxygen content and lower perfusion pressure.2 Coronary perfusion depends on elevated pulmonary vascular resistance (PVR); as PVR falls in the neonatal period, blood flow increases to the lungs, creating coronary steal and resultant ischemia. Anesthetic goals include maintaining coronary perfusion pressure by maintaining PVR and myocardial contractility.3 A ductus arteriosus maintained with prostaglandin may be the only supply of oxygenated blood to the coronaries.1 The baby depicted in these images had elevated pulmonary pressures of unclear etiology, which allowed survival to 8 weeks of age ...

To the best of our knowledge, this is the first report of a fistula between the left coronary artery and coronary sinus successfully diagnosed by prenatal echocardiography. To date, few cases of isolated CAVF have been diagnosed prenatally [4567891011]. All isolated CAVFs that were diagnosed prenatally drained into the cardiac chambers, and there were no cases with connections to the vascular structures rather than the cardiac chambers, such as the pulmonary artery, coronary sinus, and superior vena cava. In our case, prenatal ultrasonography was sensitive enough to diagnose CAVF draining into the coronary sinus.. Although the normal coronary artery is usually difficult to visualize prenatally because of the small size of the vessel, coronary malformations, such as CAVF, can be diagnosed with a high accuracy by fetal echocardiography. In this case, we clearly demonstrated the fistulous tract connected to the dilated coronary sinus. When the echocardiographic findings, such as cardiomegaly, ...

Iyong Tapat Kaibigan CAX5 owned by Stephanie Markgraf of Locust Grove, VA. Photo by Kate Renner. Kai, a 5 year-old Catahoula Leopard dog mix, loves lure coursing. There is no other way the rescue dog would rather spend his time than chasing the lure around the field. His great skill at the sport had earned him four AKC Coursing Ability Excellent (CAX) titles, making him the most titled All-American Dog in the sport.. So when Kai started limping after a competition, Stephanie thought he was just tired or might have strained a muscle or ligament.. The next day Kai was at his veterinarians office for diagnosis and treatment. X-rays confirmed cranial cruciate ligament disease. His limping was not the result of trauma but a disease.. Kai was referred to a surgeon that specialized in his condition. The doctor confirmed both knees needed treatment so a staggered surgery plan was necessary. The left knee was operated on in November 2015 and the right knee in December 2015. Both surgeries went well, and ...

2 Departments of Cardiovascular Surgery, Başkent University Faculty of Medicine, Ankara, Turkey. DOI : 10.24953/turkjped.2020.04.011 Background and objectives. In this study, we aimed to review the treatment options and long-term problems of patients who were diagnosed with coronary artery fistulae (CAF) in our institution. We also tried to determine the most appropriate time for treatment of this condition.. Method. From 2000 to 2018, the medical records of 56 patients (33 males and 23 females) who had CAF diagnoses were retrospectively reviewed.. Results. The mean age of the patients at the time of diagnosis was 3.9 ± 4.6 years (range, 1 month to 18 years) and the mean duration of the follow-up period was 7.4 ± 4.5 years (range, 1 year to 17.5 years). The right coronary artery (RCA) was the most common origin site for CAF, the left main coronary artery (LMCA) was the second most common origin site whereas the left anterior descending coronary artery (LAD) was the third most common origin ...

This thesis focus on the physiological information, on left ventricular (LV) motion in the long axis, evaluated in routine coronaty angiography sequences and based on previous knowledge from echocardiographic studies. As coronary angiography has become a very frequent examination, a method for assessment of LV function from routine coronary angiograms would probably have a significant impact on clinical work. Therefore, the motion of the left coronary artery is analysed in the studies described below.. In a pilot study of 84 patients, refetTed for coronaty and LV angiography, the systolic descent of the left coronary ostium (LCO) towards apex was measured. This simple manual measure from routine coronary angiograms showed a mean amplitude of 9.6 mm (range 3.0-15.0) and significant linear correlation to ejection fraction (EF) (r = 0.72, SEE = 10.1, p , 0.001).. In the second study, including 28 patients, coronary angiography and echoeardiography was used for measurement of circumflex artery ...

By Richard R. Heuser, MD, and Khalid Naqi, MD. Patient History. A 65-year-old army veteran presented with unstable angina. An outside angiogram revealed calcific ostial and proximal right coronary artery (RCA) stenoses.. Methods. The radial approach was utilized with an Ikari 1.5 guiding catheter. The lesion was crossed with a Whisper wire and utilizing the FineCross (Terumo) catheter, this was exchanged for the ViperWire (CSI). Following this, the CSI device debulked the proximal areas of stenosis. An AngioScore balloon performed further enlargement of the lumen. Finally, a 3.5 mm x 33 mm stent was placed (Xience). To optimize the ostial result, we placed the Flash ostial device (Cardinal Health). The final result revealed an appropriate apposition at the origin of the RCA vessel. By deploying a few millimeters more proximal, the Flash ostial device allowed us to get the optimal result at the origin of the vessel.. Discussion. Ostial calcific stenosis always poses a challenge during ...
The circumflex artery, fully titled as the circumflex branch of the left coronary artery, is an artery that branches off from the left coronary artery to supply portions of the heart with oxygenated blood. The circumflex artery itself divides into smaller arterial systems.

Dr. Matos-Cruz responded: Depends on anatomy. Goal if possible is to achieve, atrioventricular and ventriculoarterial concordance as best possible. Some transpositions of the great arteries are congenitally corrected if baby born with atrioventricular and ventriculoarterial discordance. Is it d or l tga, how many concomitant anomalies are present. If d-tga, no vsd, good valves, no coronary anomalies, good lv and rv, ASD closure and jatene best.
The LAD dives quiet deep into the myocardium. Myocardial bridging is often asymptomatic, however in this case it was presumed to be the cause of the symptoms due to both the absence of any CAD and the severity of bridging.
The medial femoral circumflex artery branches off from the deep femoral artery and supplies oxygenated blood to the muscles of the middle of the thigh and hip joint.

Takeuchis diminutive TB228 released at Intermat is the most recent in a long line of compact excavators dating back to 1971. During that time, the Japanese company has made many revisions, and the new model comes with a two-year, 2000-h full machine warranty. Compact excavators must remain small, and the TB228 uses a Tier-4 Yanmar three-cylinder diesel developing 23.5 hp (17.5 kW) and 63 lb·ft (85.3 N·m). A one-touch engine decelerator, electronic monitoring system, and automatic bleed system are installed for safety and convenience. Power is sent through a hydrostatic drive system to either steel or rubber tracks. Three permanently sealed rollers per side help to distribute the 4-psi (28-kPa) ground pressure. Maximum speeds of 1.7 mph (2.8 km/h) in low range and 3 mph (4.9 km/h) in high range are possible. The hydraulic system uses twin variable-displacement piston pumps with two gear pumps to power the vehicle functions. The arm has two-way auxiliary hydraulics, and auxiliary hydraulics ...
