RESUMEN
Origin of the right coronary artery from the main pulmonary artery is an anomaly that can cause formation of a left-to-right coronary shunt, leading to myocardial ischemia and early onset of congestive heart failure. We describe a case in which magnetic resonance imaging was able to show the anomalous origin of the right coronary artery, and magnetic resonance phase velocity mapping was able to demonstrate the presence of a left-to-right shunt through the coronary artery by showing retrograde flow in the right coronary artery.

An intrapericardial left atrial appendage aneurysm is described in a 36 year old female. She was asymptomatic except for intermittent palpitations. The aneurysm was initially diagnosed by 2D-echocardiogram and confirmed by pulmonary cineangiogram. In addition to compression and indentation of the anterolateral wall of the left ventricle, hypokinesis was noted, which we believe has not been reported previously, in association with the left atrial appendage aneurysm, and which improved after surgical resection. The patient is symptom-free at a 5 year follow-up. A review of the literature is presented.
