A previously unknown coronary artery anomaly is reported: origin of the left coronary artery from the right pulmonary artery. This unusual anomaly can probably be explained by the theory of dual embryonic development of the coronary arteries from angioblastic buds in the truncus arteriosus. It is thought that these buds anastomose with a capillary network that is developing on the surface of th...

Abstract : Intercoronary communication or coronary arcade is a rare congenital coronary artery anomaly in which there is an open-ended circulation with unidirectional or bidirectional blood flow between two coronary arteries. A 85-year-old woman was admitted to the emergency service with typical chest pain. There was no evidence of transmural myocardial infarction in the results of electrocardo...

At birth an infant was found to have an unusual series of abnormalities with a coronary sinus type atrial septal defect complicating pulmonary atresia with an intact ventricular septum and Ebstein's anomaly. The functionally important anomalies were diagnosed by echocardiography and cardiac catheterisation. The coronary sinus defect and Ebstein's anomaly were detected only at necropsy. Although...

The left coronary artery originating from the pulmonary trunk is a rare congenital anomaly, known as Bland-White-Garland syndrome (BWGS). Most patients with this anomaly of the coronary artery system die during early childhood (Wesslhoeft et al., 1968). In this case report, we describe an adult patient with nonviable myocardium most likely due to chronic ischemia. To the best of our knowledge, ...

Coronary artery fistula is a rare congenital anomaly. Most patients with this anomaly are asymptomatic, but some may develop heart failure, myocardial ischemia or arrhythmias. We report a case of a patient who presented with myocardial ischemia secondary to persistent Thebesian veins. Coronary angiography demonstrated a marked capillary blush draining into the left ventricular cavity through mu...

BACKGROUND Left coronary artery arising from the right sinus of Valsalva is an uncommon congenital coronary anomaly that seems to be associated with sudden death in young patients. CASE PRESENTATION We report a case of cardiac arrest in a 59-year-old patient after sexual intercourse and Sildenafil ingestion. A coronary arteriography and an angiographic computed tomography scan subsequently re...

Spontaneous coronary artery dissection (SCAD) and woven coronary artery anomaly (WCAA) are relatively rare. A few of the previously reported woven coronary artery cases have involved in a single coronary artery. We present an unusual woven case involving all coronary arteries and two patient with SCAD. We have also reviewed the literature related to these disease, as they resemble one another.

Coronary arteriovenous fistula (CAVF) is a rarely encountered congenital coronary anomaly, in which coronary artery blood flow bypasses the myocardial capillary network and usually drains to a heart chamber or great vessel. It is usually asymptomatic. However, the risk of symptoms and complications increases with age. High output heart failure, pulmonary hypertension, myocardial ischemia and in...

Communication between the coronary arteries and the cardiac chambers is a rare event. In the 22,500 post-mortems performed at the General Hospital, Singapore, over the past decade, there were some 520 cases of congenital heart disease. In this material there were three examples of this unusual anomaly, all occurring in infants of Chinese race. As about 30 cases of this anomaly have now been des...
