Unifocalization of Major Aorto‐Pulmonary Collateral Arteries in Pulmonary Atresia and Ventricular Septal Defect Using Antibiotic Sterilized Pulmonary Homograft: A Case Report

A unifocalization procedure in a 9-year-old girl with pulmonary atresia, ventricular septal defect, and major aortopulmonary collateral arteries (MAPCAs) was performed using an antibiotic sterilized pulmonary homograft. A tailored pulmonary homograft was used as an interposition graft to anastomose the pulmonary artery to the larger MAPCA after a side-to-side anastomosis had been done between the two MAPCAs. The pulmonary homograft was connected to the right subclavian artery with a 6-mm Gore-Tex shunt. Postoperative oxygen saturation (SaO2) levels were satisfactory and a postoperative angiogram showed good unifocalization of the pulmonary vasculature. (J Card Surg 1994;9:115–119)
