OBJECTIVES The aim of the present study was to investigate whether right coronary artery chronic total occlusion (CTO) carries prognostic implications in patients undergoing drug-eluting stent-supported percutaneous coronary intervention (PCI) for unprotected left main disease (ULMD). BACKGROUND No data exist on the prognostic implication of CTO in patients undergoing PCI for ULMD. METHODS ...

BACKGROUND Right ventricular hypoplasia (RVH) is often caused by tricuspid valve atresia and pulmonary valve atresia. this condition leads to low right ventricular blood volume and right ventricular maldevelopment. But, in adults, the main cause of RVH may also be associated with alloplasia of the right coronary artery, which results in an insufficient blood supply to the right ventricular myoc...

Introduction: Coronary endarterectomy is not a perfect procedure. However, it is sometimes the only available alternative for cardiac surgeons in patients suffering from diffuse coronary artery disease. According to a large volume of studies, coronary endarterectomy results (such as survival, recurrence of the symptoms of myocardial ischemia, and graft patency) are not as satisfactory as standa...

Right Coronary Artery (RCA) originating from left anterior descending artery is a very rare congenital coronary artery anomaly. A 66-year-old man presented with hypertension and complaints of exertional chest pain. The angiography was performed. Aortic root angiography showed no coronary ostium originating from the right sinus of valsalva. Right coronary artery was visualized as anomalously ori...

Coronary artery anomalies represent a disease spectrum from incidental to life-threatening. Anomalies of coronary artery origin and course are well-recognized in human medicine, but have received limited attention in veterinary medicine. Coronary artery anomalies are best described in the dog, hamster, and cow though reports also exist in the horse and pig. The most well-known anomaly in veteri...

Single right coronary artery with congenital absence of left coronary artery is one of the rarest coronary artery anomalies. Most coronary anomalies are asymptomatic and incidental findings. We report a case of single right coronary artery with congenital absence of left coronary artery detected by coronary CT angiography. Physical examination revealed a well-nourished female with a blood press...

BACKGROUND Most coronary artery anomalies are congenital in origin. This study angiographically determined the prevalence of different forms of anomalous aortic origins of coronary anomalies and their anatomic variation in a selected adult Lebanese population. Correlation between these anomalies and stenotic coronary atherosclerotic disease was also investigated. METHODS 4650 coronary angiogr...

Single coronary artery is a rare coronary artery anomaly. Very few previous reports of this anatomical malformation in swine have been found. A 22 kg Yorkshire X Landrace F1 crossbred castrated male swine was presented for enrollment in a coronary stent implantion study. Coronary angiography revealed a single coronary artery arising from the right aortic sinus. The right coronary artery and ano...
