Herein we report the diagnostic potential of cardiac computed tomography (cCT) to delineate the origin and course of an anomalous right coronary artery (RCA) originating from the midpart of the left anterior descended artery (LAD) in an adult with no other form of congenital heart disease. The patient was referred to our institution due to exertional dyspnea and suspected coronary artery diseas...

Coronary artery anomalies are a diverse group of congenital disorders whose manifestations and pathophysiological mechanisms are highly variable, with a global incidence of 5.64% [1]. The classification of coronary anomalies is based on the abnormalities seen in one or more site of origin, course, termination and branches of the major coronary arteries. Some of these anomalies are common, while...

OBJECTIVE To assess the patency of the pedicled right internal thoracic artery with an anteroaortic course and compare it to the patency of the left internal thoracic artery , in anastomosis to the left anterior descending artery in coronary artery bypass grafting by using coronary CT angiography at 6 months postoperatively. METHODS Between December 2008 and December 2011, 100 patients were s...

To determine whether compensatory enlargement of atherosclerotic coronary arteries occurs and to what degree it affects the angiographic assessment of coronary artery disease, we performed postmortem coronary angiography of 30 human hearts with suspected coronary artery disease and studied 70 histologic cross sections of the proximal left anterior descending artery and proximal right coronary a...

Recent evidence suggests an association between vasospastic angina and Brugada syndrome. Here we present two cases of coronary artery disease who presented with ECG abnormalities which might have been provoked or enhanced by ischemia of the conus branch of the right coronary artery. The 12-lead ECGs demonstrated normal sinus rhythm in these two cases. Interestingly, a saddle back or coved type ...

Coronary artery fistula (CAF) is an abnormal communication between an epicardial coronary artery and a single or multiple cardiac chambers, large vessels or other vascular structures (1). Although it is a rare condition, it is the most frequent congenital coronary anomaly (2), and it accounts for 0.2-0.4% of congenital cardiac anomalies. Approximately 50% of pediatric coronary vasculature anoma...

Congenital abnormalities of coronary arteries may predispose to life-threatening sudden cardiac events. We present a case of aborted sudden cardiac death in a patient who was diagnosed as having single coronary artery originating from right coronary sinus. The vessell divided into critically stenosed left main trunk and significantly narrowed right coronary artery. The patient was successfully ...

We report a 72-year-old woman with severe congenital stenosis of the left coronary artery orifice and clinically significant atherosclerotic changes in both the right and left coronary arteries. The stenotic ostium was located at the point at which the left and posterior aortic valve leaflets joined to form the left commissure, just at the distal vertex of the left interleaflet triangle, betwee...

We report a case of a patient in whom collateral flow originating from the left anterior descending coronary artery was initially associated with a right coronary artery stenosis; seven months after successful angioplasty of the right coronary artery lesion, a severe left anterior descending stenosis developed and induced reversed collateral flow from the right coronary artery through the same ...

A 65-year-old man was admitted to his local hospital with troponin-positive acute coronary syndrome. The patient developed signs of acute heart failure and was immediately transferred to our center. Echocardiography demonstrated a pericardial mass (8 5 cm) with compression of the right atrium (Figure 1 and online-only Data Supplement Movie I) and a reduced contractility of the posterior left ve...
