1/191. Anomalous left coronary artery arising from right sinus of valsalva could be a minor congenital anomaly--a case report and review of the literature.Left coronary artery arising from the right sinus of valsalva is a rare congenital coronary anomaly. This anomaly is either benign or serious, depending on the relation of the anomalous left coronary artery to the aorta and pulmonary artery. Potentially serious anomaly is associated with sudden cardiac death and warrants prophylactic coronary bypass surgery. A rare case of anomalous left coronary artery arising from the right sinus of valsalva is reported, documented by coronary angiography; however, it took a safer course between the aorta and pulmonary artery. Prophylactic surgery was not performed, for this benign anomaly may not carry the same risk of sudden cardiac death.- - - - - - - - - - ranking = 1keywords = sudden cardiac death, sudden cardiac, cardiac death, sudden, death (Clic here for more details about this article) |
2/191. Catheter-based techniques for closure of coronary fistulae.This study details different methodologies of percutaneous closure of arteriosystemic and arteriovenous coronary fistula. Seven patients underwent transcatheter intervention of 10 fistulas, with 7 fistulas successfully closed: 6 with embolic coil devices and 1 with a covered stent obstructing the fistula ostium. The major complication encountered was one death as a result of device recoil into a major epicardial vessel. Percutaneous transcatheter closure of coronary fistulas appears to be simple, facile, and effective. However, device recoil into an undesired arterial segment, while irritating in a noncoronary arterial tree, may be catastrophic when occurring in an epicardial coronary artery.- - - - - - - - - - ranking = 0.0034070216307775keywords = death (Clic here for more details about this article) |
3/191. Sudden death and cerebral anoxia in a young woman with congenital ostial stenosis of the left main coronary artery.We report a 36-year-old woman with ventricular fibrillation, subsequent sudden clinical cardiac death, and a prolonged brain anoxia. After a successful resuscitation coronary angiography revealed congenital ostial left main coronary artery (LMCA) stenosis. Surgical anastomosis of the left internal mammary artery (LIMA) to LAD led to a complete recovery. Postoperative electrophysiological examination, mainly programmed ventricular stimulation, failed to excite any rhythm disturbances. Cathet. Cardiovasc.

4/191. A case for routine screening of coronary artery origins during echocardiography: fortuitous discovery of a life-threatening coronary anomaly.Anomalous origin of the left main coronary artery from the right sinus of valsalva with retropulmonary course is a rare congenital abnormality. It is associated with a high incidence of sudden cardiac death, particularly among young, athletic individuals. Many of these individuals do not have symptoms before sudden death, and the diagnosis is usually made at postmortem examination. We present a case of a 15-year-old boy who was evaluated for a systolic click with routine 2-dimensional echocardiography. The anomalous coronary artery was serendipitously identified, allowing surgical intervention. Coronary artery origin and proximal course should be visualized on routine echocardiography in the pediatric population.- - - - - - - - - - ranking = 0.54994327961068keywords = sudden cardiac death, sudden cardiac, cardiac death, sudden death, sudden, death (Clic here for more details about this article) |
5/191. myocardial bridging.Human myocardial bridging is a normal anatomic variation in which a coronary artery is bridged by a short segment of myocardium. It can cause variable degrees of systolic obstruction. The majority of patients are asymptomatic. A wide variety of syndromes can occur, including myocardial infarction and sudden death. All patients with myocardial bridges have systolic artery compression, but it is postulated that ischemia develops only in those who have a concomitant decrease in diastolic coronary artery blood flow. Surgical removal of the myocardial bridge can be curative, and various other treatments can alleviate symptoms. The overall prognosis is good.- - - - - - - - - - ranking = 0.049943279610677keywords = sudden death, sudden, death (Clic here for more details about this article) |
6/191. A 72 year old woman with ALCAPA.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.- - - - - - - - - - ranking = 0.0034070216307775keywords = death (Clic here for more details about this article) |
7/191. Left coronary artery anomaly: an often unsuspected cause of sudden death in the military athlete.More than 300,000 cases of sudden cardiac death (SCD) occur in the united states each year. Left coronary artery anomaly (LCAA), although rare, is second only to hypertrophic cardiomyopathy as the most common cause of SCD associated with structural cardiovascular abnormalities. This case illustrates SCD secondary to LCAA in a military athlete. A 19-year-old soldier collapsed after an 8-km run. On arrival at the emergency room, he was unresponsive and in asystole. Despite successful resuscitation and aggressive management, the patient died the next morning. autopsy revealed an anomalous left coronary artery. LCAA-associated SCD is rare and usually seen in young individuals who collapse (and/or die) while exercising. A substantial proportion of these individuals experience prodromal symptoms of exertional chest pain, syncope, and/or sudden collapse. Early recognition and intervention are key to survival. Rapid, early imaging and invasive therapeutic measures leading to surgical correction may be the difference between life and death.- - - - - - - - - - ranking = 0.71392209707564keywords = sudden cardiac death, sudden cardiac, cardiac death, sudden death, sudden, death (Clic here for more details about this article) |
8/191. Acute myocardial infarction in a patient with anomalous left coronary artery origin and primary antiphospholipid syndrome.Anomalous left main coronary artery (LMCA) originating from the right coronary sinus and running between the aorta and pulmonary trunk is a rare congenital condition. Although this disease is known to be associated with myocardial infarction and sudden death, the precise mechanism is uncertain. A 14-year-old male with this anomaly developed myocardial infarction during exercise complicated by primary antiphospholipid syndrome. He was admitted to hospital with persistent chest pain and sudden cardiac collapse that occurred while he was running. cardiac catheterization demonstrated a narrowed segment in the LMCA and impaired blood flow, prompting a diagnosis of extensive anterior myocardial infarction. Emergency bypass surgery was performed using a single saphenous vein graft to the left anterior descending artery. Postoperative angiography showed the presence of an anomalous LMCA arising from the right sinus of valsalva and running between the great vessels. The aortic samples were pathologically normal. He was discovered to also have primary antiphospholipid syndrome and was discharged without symptoms after warfarin therapy. Complicated primary antiphospholipid syndrome may trigger myocardial infarction in asymptomatic patients with this type of coronary anomaly.- - - - - - - - - - ranking = 0.21285747009047keywords = sudden cardiac, sudden death, sudden, death (Clic here for more details about this article) |
9/191. Anomalous origin of the main stem of the left coronary artery from the non-facing sinus of valsalva associated with sudden death in a young athlete.A young female athlete is described with anomalous origin of the main stem of the left coronary artery from the non-facing sinus of valsalva who sustained myocardial infarction and died suddenly after physical exertion. autopsy findings illustrated the mechanistic importance of acute angle take-off of the left main coronary artery and a slit-like orifice, which was likely compressed and obstructed by acute expansion of the aortic wall. This rare type of coronary anomaly has been regarded as having little clinical significance, but it can lead to sudden cardiac death under physical exertion.- - - - - - - - - - ranking = 0.71051507544487keywords = sudden cardiac death, sudden cardiac, cardiac death, sudden death, sudden, death (Clic here for more details about this article) |
10/191. adult type anomalous origin of the left coronary artery from the main pulmonary artery: report of one case.Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA syndrome) is a rare disease. Most of the cases suffer from myocardial infarction, congestive heart failure or even death during the early infantile period, and thus are called "infantile type". We present one five-year-old girl with ALCAPA syndrome, adult type, who was initially suspected to be a case of atypical Kawasaki disease (KD) complicated with coronary arterial aneurysms. Due to persistent dilatation of the coronary artery after medical treatment for one year and a turbulent flow noticed between the left coronary artery (LCA) and the main pulmonary artery (MPA), cardiac catheterization was arranged. The diagnosis was established from the coronary cineangiography in spite of a direct connection between the aorta and LCA revealed from the echocardiogram. Thereafter open heart surgery was undertaken. diagnosis of ALCAPA syndrome can be made by echocardiogram, but this is not fully satisfactory. Selective coronary cineangiography remains the definitive diagnosis. Although the patients of adult type are more asymptomatic, surgical correction should be undertaken as soon as the diagnosis is established since a substantial risk is still present.- - - - - - - - - - ranking = 0.0034070216307775keywords = death (Clic here for more details about this article) |
