Anomalous origin of the right coronary artery from the left sinus of Valsalva is a rare but clinically significant congenital abnormality, difficult to diagnose angiographically. We describe a patient in whom magnetic resonance imaging was used to delineate the anomalous course of the right coronary artery following angiographic demonstration limited by technical considerations.

This is the first presentation of anomalous origin of right coronary artery (RCA) from mid-left anterior descending (LAD) coronary artery. A 77-year-old male was catheterized because of recent onset of fatigue during exertion. The LAD demonstrated 50-60% narrowing just proximal to the anomalous origin of the RCA. The patient was maintained on oral medication.

Anomalous origin of the left coronary artery from the right sinus of Valsalva is an anatomical abnormality that is usually associated with myocardial ischemia and sudden death. Although this abnormality may coexist with obstructive atherosclerotic coronary disease, disease is not usually found in the anomalous course of the artery. When this coronary anomaly and obstructive coronary disease are...

BACKGROUND Coronary artery anomalies are rare, accounting for about 0.3-1.3% of patients undergoing diagnostic coronary angiography. Interventions in these cases are still rare, and therefore pose technical challenges during intervention. CT Angiography provides a non-invasive means of assessment of coronary artery disease and also shows the anatomy of the coronary tree. This helps in knowing t...

Anomalous origin of the right coronary artery from the left sinus of Valsalva is a rare congenital anomaly but a relatively frequent cause of sudden death in the young. The medical records of 4 consecutive patients with this anomaly were retrospectively reviewed. The first 2 patients underwent coronary artery bypass and had early graft failure. The next 2 patients underwent coronary reimplantat...

Anomalous origination of a coronary artery from the opposite sinus of Valsalva is an uncommon congenital anomaly. Intervention for concurrent coronary artery disease is challenging due to the location of the ostia, the takeoff of the vessel as well as the course of the artery in question. It is also important, where possible, to exclude a "malignant" course as the most common adverse outcome fr...

BACKGROUND AND OBJECTIVES It has been demonstrated that the anomalous origin of coronary arteries (AOCA) are generally asymptomatic and rare diseases. However, some cases can cause severe life threatening events. To detect these anomalies, coronary angiographies and autopsies were used to detect coronary artery anomalies, but these procedures have limitations because of their invasiveness. The ...

Coronary artery fistula (CAF) is defined as a rare anomalous connection between a coronary artery and a major vessel or a cardiac chamber. We report a case of a left anterior descending coronary (LAD) stenosis and coronary artery fistula between the LAD coronary artery and the pulmonary artery (PA). CAF is often diagnosed by coronary angiogram. We describe our diagnostic approach and review the...

Coronary artery anomalous course is rare, reported incidence is approximately 0.3-1.3% of patients undergoing coronary angiography and approximately 1% of routine autopsy examinations. A single coronary artery is an unusual congenital anomaly where only one coronary artery arises from the aortic trunk from a single coronary ostium, supplying the entire heart. We describe here a rare case with a...
