Reconstruction of left main coronary artery with subclavian artery free graft in an infant.

We report the case of a 3-month-old infant with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) with absent left main coronary artery (LMCA). She underwent repair by reimplantation technique with the construction of a short LMCA using two opposite flaps. Two months later she was re-admitted in cardiac failure. Occlusion of the reconstructed LMCA was found by angiogram. At reoperation the right subclavian artery was used as a free interposition graft to reconstruct the LMCA. The post-operative course was uneventful. At 8 months she was asymptomatic and LMCA patency was demonstrated by angiogram.
