title: [Right ventricular outflow tract reconstruction for pulmonary atresia with ventricular septal defect: the possibility of ventriculo-arterial direct anastomosis].
abstract: Between September 1997 and December 2000, 29 patients with pulmonary atresia associated with ventricular septal defect were undergone corrective surgery. The age at operation ranged from 24 days to 14.7 years. The 5 patients were younger than 3 months. The body weight at operation ranged from 1.5 kg to 35.8 kg. 10 patients had MAPCAs. 21 patients had been undergone modified Blolock-Taussig shunt and/or uniforcalization of pulmonary artery (PA). We could perform right ventricular outflow tract reconstruction with ventriculo-arterial direct anastomosis in 19 patients (65%) (4/10; patients with MAPCAs, 3/5; younger than 3 months). We performed pulmonary angioplasty on stenotic and/or underdeveloped leasions as a concomitant procedure in 13/19 cases. Our technique is composed of 4 points, (1) fully mobilizing central and distal pulmonary artery (PA), (2) dissecting the PA with connective tissue together, (3) pulmonary arterial wall flap, (4) right ventricular outflow tract reconstruction during cardiac arrest.
