[Surgical treatment of anomalous origin of the left coronary artery from the pulmonary artery].
OBJECTIVE
To introduce the experience in surgical correction of anomalous origin of the left coronary artery from the pulmonary artery in 8 patients.


METHODS
From 1991 August to 1999 March, 8 patients underwent surgery. Intrapulmonary tunnel procedure was performed in 7 patients, and coronary artery bypass grafting using the saphenous vein in 1. Mitral valve incompetence was repaired in 1 patient. ECG, echocardiographic and angiographic studies were made in all patients. 7 patients were followed up for 327 months (mean 46.8 +/- 10.7) months.


RESULTS
No hospital deaths and later deaths occurred nor major complications during hospitalization. Because of suture of intrapulmonary tunnel loose, artery-pulmonary artery leakage 1 patient was reoperated on successfully. Follow-up showed cardiac function New York Heart Association function class I, mean LVMD (46.4 +/- 3.7) mm, vs mean (54.4 +/- 2.8) mm before the operation (P < 0.01), and mean EF (69.4 +/- 2.3)% vs mean 59.6% +/- 2.8% before the operation (P < 0.05).


CONCLUSIONS
Anomalous origin of the left coronary artery from the pulmonary artery is a very rare congenital malformation. To correct the anomalous origin of the left coronary artery from the pulmonary artery is to reconstruct the normal two-coronary system and to treat the other associated diseases. Intrapulmonary tunnel operation is easy to perform satisfactorily.
