introduction: although coronary endarterectomy is not an ideal procedure, it is the only available option for cardiac surgeons in some patients with diffuse coronary artery disease. based on the majority of conducted studies, the results of coronary endarterectomy (including survival, graft patency, and recurrence of the symptoms of myocardial ischemia) are less prevalent than standard coronary...

origination of the right coronary artery (rca) from the left anterior descending (lad) artery is a case of single coronary artery. it is an extremely rare coronary artery abnormality and usually an incidental finding during coronary angiography. a 73-year-old man with a medical history of hypertension arrived with chest pain. medical therapy started for st elevated myocardial ischemia. during h...

Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

coronary artery disease is one of the leading causes of morbidity and mortality especially in the indusirialzcd societies. this retrospective study was carried out on 385 patients who were referred to shariati and jamaran hospitals from 1992 till 1997 and who underwent coronaty artery bypass grafting. the objective was to obtain a descriptive analysis of the important factors in this population...

myocardial bridging with systolic compression of the left anterior descending coronary artery (lad) may be associated with myocardial ischemia. in symptomatic myocardial bridging unresponsive to medical treatment, surgical unroofing of the left lad can be performed. little information is available about the long-term prognosis of patients with this coronary anomaly after the surgical unroofing,...

background: more diagnostic techniques require a better understanding of the forces and stresses developed in the wall of the left ventricle. the aim of this study was to differentiate significant coronary artery disease (cad) patients using a non-invasive quantification of myocardial wall stress in the diastole phase. methods: sixty male subjects with sinus rhythm (30 patients with significant...

OBJECTIVE Minimally invasive multiple vessel revascularization has been accomplished using all arterial graft concepts and aortocoronary vein grafts. The aim of the present study was to determine the technical feasibility of minimally invasive axillary artery to coronary artery vein grafting in the human cadaver. METHODS In seven human cadavers the axillary artery was approached bilaterally v...

Several types of left anterior descending artery anomalies have been detected. In these anomalies, left anterior descending artery usually originates from the right coronary artery or right sinus of Valsalva. A case of left anterior descending artery arising as a terminal extension of posterior descending artery presented. This anomaly seems rather rare.

traumatic coronary artery-cameral fistulas (tcaf) are rare and may present secondary to penetrating injuries (80%) or iatrogenic traumas. early operative intervention remains the recommended treatment modality for accidental traumatic coronary artery fistulas. we report the case of a 17-year-old man who presented with left anterior descending coronary artery-right ventricle fistula following pe...

cor triatriatum   sinistrum is a rare congenital cardiac malformation, accounting for about 0.1-0.4% of all congenital heart diseases and characterized by the presence of a fibromuscular membrane that subdivides the left atrium into two chambers in the classical form. while classic cor triatriatum in most patients can be observed during the neonatal period or early infancy, it is very rare in a...
