Abstract:
A patient with pulmonary atresia with ventricular septal defect and major aortopulmonary collateral arteries without an intrapericardial pulmonary artery (PA) underwent a one-stage total correction, including both branch PA reconstructions, with a bovine pericardial roll at the age of 42 months. She was readmitted 54 months after the operation because of extracardiac conduit bacterial endocarditis and pulmonary infarction. The bovine pericardial roll between the right and left PAs was enucleated, and the surrounding fibrotic tissue (peel) was used as a new branch PA vascular conduit. A cardiac catheterization performed 86 months after the peel operation showed no aneurysmal dilatation, stenosis, or thrombotic occlusion.
