RESUMO
Anomalous left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart disease that may present isolated or may be associated with other cardiac malformations. Most of the patients develop symptoms during infancy but some may remain asymptomatic up to adulthood. Symptoms range from mild distress to severe irritability and feed intolerance. We report a case of a five-month-old male child who presented with congestive heart failure and was diagnosed as a case of ALCAPA with left atrial and left ventricular dilation based on two-dimensional echocardiography and computed tomography (CT) coronary angiogram. Left main coronary artery was shown to be arising from the posteroinferior wall of main pulmonary artery. Various surgical approaches have been suggested in the repair but the Takeuchi technique was preferred owing to its origin from the non-facing sinus of the pulmonary artery and co-existing dilatation of left atria and ventricle. The surgery was uneventful and there were no postoperative complications. A cardiac CT dynamic study was also done on the follow-up visit five months later and no signs of abnormality or complications were reported. Early intervention is necessary to prevent irreversible cardiac complications and early mortality.
