RECENT reports have indicated that anomalous coronary arteries originating from the pulmonary artery may act as a channel for left-to-right shunt.1-4 Thus a large portion of the coronary blood flow may bypass the coronary capillary bed, pass through arterial anastomoses, and enter directly into the pulmonary artery by retrograde flow through the anomalous coronary with resultant myocardial isch...

BACKGROUND The aim of this study was to investigate the incidence, origins and courses of coronary artery anomalies using a combination of angiographic and surgical methods in Turkish children with tetralogy of Fallot (ToF). METHODS Seventy-seven patients in whom coronary artery anomalies had been identified by angiography and/or at operation out of 549 ToF and 58 Fallot-type double outlet ri...

A case of aortopulmonary window associated with an anomalous origin of the right coronary artery from the pulmonary artery in a 3-month-old boy is reported. Angiographic diagnosis could be difficult because of the simultaneous filling of both great arteries that obscure the origin of the anomalous vessel; however, a careful evaluation of the angiogram may contribute to an accurate diagnosis. Th...

Aorto-pulmonary septal defects and anomalous origins of left coronary artery from pulmonary artery are briefly discussed. The difficulties of diagnosis and surgical correction are put forward in a situation when the left coronary artery arises from a site of high pressure and saturation, such as the pulmonary artery in the presence of an aorto-pulmonary septal defect, as in the case described.

Coronary artery fistulas are rare anomalies of the coronary arteries that may sometimes cause symptoms by shunting blood flow away from the myocardial capillary network. We report the case of a 46-year old lady which shows the right coronary cusp giving rise to left main coronary artery called anomalous origin of a coronary artery (AOCA), and also a fistula between the left coronary artery and ...

Coronary artery fistula (CAF) is described as an anomalous connection between a coronary artery and a major vessel or cardiac chamber. It can result in myocardial ischemia, heart failure, pulmonary hypertension, bacterial endocarditis, and rupture of aneurysmal vessels [1]. The majority of these fistulae originate from the left anterior descending artery or from the right coronary artery [2]. S...

BACKGROUND Coronary arteries originating from the right coronary ostium in the ascending aorta represent a very rare anatomic presentation. Also, the presence of a single coronary ostium is an extremely rare finding. CASE PRESENTATION We present the case of a 74-year-old Albanian man from Kosovo. He had unstable angina due to critical triple vessel disease and a single coronary artery origina...

A 45-year-old woman with angina pectoris, beginning at the age of 16 and progressing to produce incapacitation, was found to have an anomalous left coronary artery arising from the pulmonary artery. Because of the severity of symptoms and progression' of disability, the anomalous artery was ligated at its origin from the pulmonary artery. Pressure in the left coronary system increased from 35/1...
