Abstract

Anomalous origin of the left anterior descending coronary artery from the pulmonary artery is a rare variant of anomalous origin of the left main coronary artery from the pulmonary artery. We report on a seemingly asymptomatic patient with ALADCAPA and a small restrictive muscular ventricular septal defect diagnosed by echocardiogram in the neonatal period. Our patient underwent elective repair at 3.5 months of age after which feeding and growth improved dramatically. Multimodality imaging is helpful to confirm this rare anomaly; however, echocardiographic clues including lack of left coronary branching or an abnormal coronary course should raise suspicion for ALADCAPA. This case provides support for early repair in children with an incidental finding of this anomaly as subclinical ischemia may be under-recognized by available testing but may lead to symptoms later in life.
