In this study, we describe a very rare case of anomalous left coronary artery arising from the right pulmonary artery in association with coarctation of the aorta. A 3-month-old boy presented with refractory congestive heart failure since 20 days after birth. The initial echocardiography suggested the diagnosis of left coronary artery-to-right pulmonary artery fistula associated with coarctatio...

Anomalous coronary arteries are rare but can lead to serious complications during cardiac operations if not recognized. We report a 55-year-old woman with anomalous origin of the right coronary artery from the left ventricle, and bicuspid aortic valve stenosis. Coronary angiography and computerized tomographic angiography indicated the diagnosis preoperatively. She underwent aortic valve replac...

Coronary artery anomalies are uncommon, with a reported prevalence ranging from 0.2% to 1.6%. It is important that those who undertake coronary angiographic procedures are aware of the spectrum of these anomalies. Interventional percutaneous coronary revascularisation procedures are widely used in the management of patients with symptomatic coronary atherosclerosis. The presence of a coronary a...

Congenital absence of the left circumflex artery is a rare coronary anomaly with few reported cases in the literature. These patients are usually diagnosed incidentally when they undergo coronary angiography or coronary CT to rule out underlying coronary artery disease. In this article, we report a case of a 46-year-old man who was incidentally found to have a congenitally absent left circumfle...

The first case of successful slow pathway modulation is reported in a patient with Ebstein anomaly and recurrent atrioventricular nodal re-entrant tachycardia. Typical signals were recorded during electrophysiological study at the slow pathway region between the His bundle and the coronary sinus where ablation was performed successfully. Thus, slow pathway modulation seems to be a safe procedur...

Anomalies of the left coronary artery are very rare, with an incidence range between .3% and 1.64%. The diagnosis is generally incidental during coronary angiogram, coronary artery bypass operation, or autopsy. However, sometimes this anomaly is not recognized during CABG operation and can be responsible for the recurrence of angina after CABG operation and even compromise the outcome. We prese...

Myocardial bridging (MB) is an anatomical variation characterized by narrowing during systole of some of the epicardial coronary arterial segments running in the myocardium. It can be encountered in 0.5% to 16% of routine coronary angiographies [1]. Although it is considered as a benign anomaly, it may lead to such complications as myocardial ischemia, acute coronary syndromes, coronary spasm, ...

BACKGROUND Complications concerning the coronary arteries that are directly related to radiofrequency catheter ablation procedures have not been reported in children. Coronary artery lesions, however, have been demonstrated after the endocardial application of radiofrequency current in young animals. METHODS AND RESULTS Two boys with Ebstein's anomaly of the tricuspid valve developed clinical...

Cases in which an anomalous single coronary trunk arises from the ascending aorta are extremely rare. In percutaneous coronary intervention for the lesion of a coronary artery anomaly, several problems may occur, including selection of a guide catheter, insufficient backup force, and difficulties of stent delivery. The GuideLiner catheter, which is a coaxial guide extension having the advantage...

Anomalous origin of left main coronary artery from pulmonary artery (ALCAPA) is a very rare congenital anomaly, reported in less than 0.5% of all the congenital heart diseases. Left untreated, majority of the patients die in infancy of myocardial ischemia. We report a case with this anomaly, presented in early infancy with progressive dyspnoea, feeding difficulty and cardiomagaly on X-ray. The ...
