Abstract
Aortopulmonary window (APW) seen in association with anomalous origin of left coronary artery from pulmonary artery (ALCAPA) is extremely uncommon. When faced with this combination, ALCAPA usually goes undetected since most of the clinical and echocardiographic features of ALCAPA, including ventricular dysfunction are absent due to co-existent pulmonary hypertension. Herein we report a 5-month-old child with a large APW in whom a preoperative computed tomography angiogram facilitated the diagnosis of ALCAPA. The case is described for its rarity and the challenges faced during management. Also, it is extremely crucial that this coronary anomaly is identified and corrected during surgery, since failure to do so results in unforeseen postoperative ventricular dysfunction.
