coronary-cameral fistulas (ccfs) constitute a rare anomaly that can be incidentally detected during angiography. ccfs are solitary, large or small assemblies that originate from coronary arteries and enter one of the cardiac chambers. we describe a 29-year-old woman, who referred to our clinic with the chief complaints of palpitation, atypical chest pain, and dyspnea on exertion (functional cla...

Introduction: Coronary artery anomalies are rare clinical entities reported in 0.6% to 5.6% of diagnostic coronary angiographies. Anomalous origins of coronary arteries from distal segments are rarely reported. Presented herein is a coronary anomaly in which the circumflex artery (CX) originated as a continuation of the posterolateral branch of the right coronary artery (RCA) w...

large intercoronary communications in the absence of obstructive coronary artery disease constitute a very rare coronary artery anomaly in which there is a readily visible connection between the 2 coronary arteries with a unidirectional or bidirectional blood flow; consequently, this anomaly may be misinterpreted as a functioning collateral vessel, indicative of an unrecognized proximal coronar...

background coronary artery anomalies are not common, but could be very serious. objectives this study determines the frequency of coronary anomalies and normal variants by multi-detector-row computed tomography (mdct). patients and methods the results of cardiac mdct study in 2697 consecutive patients were analyzed retrospectively. acquisition was performed by a 64-detector row ct machine. imag...

Congenital absence of left circumflex artery is a rare congenital anomaly of the coronary arteries. The prevalence of the anomaly in different studies ranges from 0.6% to 1.3%. Of these, 80% are benign and asymptomatic and 20% are clinically important. We report a 56-year-old man presented with acute resting chest pain who was diagnosed as having acute anterolateral infarction accompanied by el...

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...

BACKGROUND A normal anatomy of coronary arteries is important to have adequate cardiac muscle blood supply especially during extraneous physical activities. This case report describes a rare coronary anomaly in which the accessory coronary artery arose from the right coronary artery, reentered the left anterior descending coronary artery, and then ran as a single vessel. CASE PRESENTATION We ...

the majority of coronary artery fistulas (cafs) are congenital. the anomaly accounts for 0.4% of congenital heart defects and approximately 50% of pediatric coronary vasculature anomalies. twenty percent of people with congenital cafs have other concomitant cardiac anomalies, most frequently aortic and pulmonary atresia and patent ductus arteriosus. it is worthy of note that caf with the tetral...
