Repair of anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) by sinus pouch technique

Abstract

A 5-month-old girl, weighing 5.3 kg, diagnosed ALCAPA underwent emergency surgery. The left coronary artery (LCA) originated from the posterior pulmonary artery (PA), and the left main trunk (LMT) was very short (1.5 mm), with moderate level of mitral valve regurgitation (MR). The distance from the origin to the pulmonary valve (Pv) was also short. A free extension conduit was created using adjacent sinus Valsalva flaps and implanted in the ascending aorta to avoid distortion of the coronary artery and the Pv.
