Τransradial artery access has recently gained widespread acceptance as the preferred approach for coronary angiography and interventions, due to its lower incidence of bleeding vascular complications compared transfemoral access. However, thrombotic occlusion radial emerged most common complication this method, impeding use in future creation arteriovenous fistulae hemodialysis patients, or a g...

Despite the remarkable advances in revascularization strategies made during the last decade, a significant proportion of patients are excluded from either percutaneous coronary intervention or coronary artery bypass grafting because of unsuitable coronary anatomy. Diffuse severe coronary artery disease, small vessel caliber, chronic total occlusions, or extremely calcified vessels are frequent ...

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...

Coronary artery anomalies may involve the origin, course, and structure of epicardial coronary arteries and occur in less than 1% of the general population. Clinical presentation ranges from being completely asymptomatic to sudden death. Multi-detector computed tomography has come a long way in the diagnosis of coronary artery anomalies since the introduction of 4 rows of detectors in scanners,...

In humans, the physiologic relation between myocardial blood flow and epicardial coronary artery anatomy remains poorly defined. With the recent development of sonicated microbubble contrast agents, it is now possible to use contrast echocardiography to assess myocardial perfusion and to correlate blood flow with angiographically identified coronary artery anatomy. The purpose of the current st...

We report a case of an anomalous origin of a right coronary artery from the left coronary sinus with an inter-arterial course, between the aorta and the main pulmonary artery. This variant has been called malignant because of its association with sudden death, especially in young asymptomatic athletes. Although these variants are rare, knowledge of cross sectional anatomy of the coronary arteri...

Three patients with angina pectoris are reported in whom occlusion of the left main coronary artery was found at coronary arteriography. In these three patients left ventricular function was well preserved. In all three the right coronary artery was dominant and there were prominent epicardial and septal collateral vessels to the territories normally supplied by the left anterior descending and...

The arterial switch operation (ASO) has evolved into the treatment of the choice for most forms of transposition of the great arteries (TGA). Despite advancement in the technical aspects of the procedure, certain anatomical variations of the coronary arteries are still considered as surgical risks. We have recently employed a novel technique for coronary artery reconstruction in ASO to achieve ...

Coronary anomalies are less frequent than acquired coronary diseases, such as atherosclerosis, and have been implicated a cause of cardiovascular events. This case report describes an incidental finding on angiography anomalous right artery with origin in the left sinus intra-arterial course, after episode aborted sudden death. The Heart Team analysis indicated percutaneous approach drug-elutin...
