BACKGROUND: Double outlet right ventricle with L-malposition of the great arteries is a rare type of double outlet right ventricle. This article reviews our experience in treating this disease surgically.

METHODS: Between September 1995 and May 1999, 9 patients with double outlet right ventricle [S, D, L] underwent modified Rastelli procedure at Fu Wai Hospital. In all patients, the two great arteries originated completely from the right ventricle. The malformation was associated with subaortic conus and L-transposition of the great arteries. The ventricular septal defect (VSD) was subpulmonary in 3 patients, and non-committed in 6. All but one patient had either pulmonary valvular stenosis or subpulmonary stenosis. No patient had any type of palliative operation before. A right ventriculotomy was made to repair the VSD with a Dacron or vascular prosthesitic patch, and an intraventricular tunnel was made between the left ventricle and the aorta. The main pulmonary artery was divided and the proximal end was closed. A homograft conduit was implanted between the inlet of the right ventricle and the main pulmonary artery. In the Rastelli procedure, the conduit is usually positioned between the right ventricular outflow tract and the pulmonary artery.

RESULTS: All patients survived and recovered uneventfully. Echocardiography demonstrated that all intraventricular tunnels and valved conduits were functioning well. The results were satisfactory.

CONCLUSIONS: Modified Rastelli procedure is an optimal method for surgically treating double outlet right ventricle with left-malposition of the great arteries. It can completely correct the right ventricular outflow tract stenosis, and right to left shunt, and avoid injuring the right coronary artery.
