Severe Tricuspid Insufficiency after Correction of Anomalous Origin of the Left Coronary Artery from the Pulmonary Artery(ALCAPA) / 대한흉부외과학회지

ABSTRACT

We report a case of an 8 years and 11 month-old male patient who had developed severe tricuspid insufficiency(TI) after correction of anomalous origin of the left coronary artery from the pulmonary artery(ALCAPA). Transthoracic echocardiogram and coronary angiography confirmed ALCAPA, ischemic mitral regurgitation and trivial TI. He underwent direct reimplantation of the left coronary artery to the aortic root by using additional cannulation at the main pulmonary artery for arterial inflow and cardioplegia delivery to the left coronary artery. After the correction of ALCAPA, transesophageal echocardiogram(TEE) revealed good antegrade flow at the aortic implantation site of the left coronary artery and severe TI(Gr III-IV/IV). Cardiopulmonary bypass was reestablished and tricuspid valve was repaired with Kay-type annuloplasty, artificial chordae formation and chordal shortening plasty. The postrepair TEE revealed trivial to mild TI.
