Excellent functional result in children after correction of anomalous origin of left coronary artery from the pulmonary artery – a population-based complete follow-up study☆

Abstract

Surgical strategy to construct a two-coronary system for a patient with anomalous origin of left coronary artery from pulmonary artery (ALCAPA) has evolved with time. Limited long-term follow-up data are available on these children. We report population-based follow-up in children operated on for ALCAPA. In total, 29 patients underwent aortic reimplantation of ALCAPA between 1979 and 2006. Twenty (69%) children were repaired with direct aortic implantation, five (17%) with a modified tubular extension technique, and four (14%) patients with an intrapulmonary baffling technique. Early postoperative mortality (<30 days) was 17%. No late mortality (>30 days) was detected. The median length of follow-up was 11 years (range 10 months-27 years). Global left ventricular function by echocardiography (M-mode) was within normal limits (>30%) in all patients one year after operation. Functionally, 80% of patients were classified in NYHA class I, 20% in NYHA II, and 0% in NYHA classes III/IV at the time of the last examination. Excellent results with good long-term outcome can be achieved in infants with ALCAPA using reimplantation techniques. Normalization of cardiac function is expected within the first year in all operative survivors with a patent coronary system.
