A 4-month-old girl presented with 2 weeks of symptoms and physical signs of heart failure. Echocardiography demonstrated marked left ventricular dilation, thinning of the myocardium with anterolateral akinesis, mitral regurgitation, a moderate pericardial collection, and an anomalous left coronary artery from the pulmonary artery. At operation there was a tense hemopericardium and a site of imminent rupture through a transmural anterior infarction. The anomalous artery was reimplanted in the ascending aorta, and an extensive infarct resection and ventricular repair performed. Support with a left ventricular assist device was required for 3 days, but the infant subsequently made a satisfactory recovery. Left ventricular rupture is a very rare complication of this lesion, but should be considered if there is evidence of a pericardial collection.
Anomalous origin of the right coronary artery from the left sinus of Valsalva is a rare congenital defect that can be difficult to diagnose by echocardiography. We describe an infant with a ventricular septal defect that was diagnosed prospectively by transthoracic echocardiography as an anomalous origin of the right coronary artery from the left sinus of Valsalva. Subcostal imaging and Doppler color flow mapping were instrumental in the echocardiographic diagnosis of this unusual coronary abnormality.
