title: Autologous pericardium patch aneurysm after ventricular septal defect closure and arterial switch operation.
abstract: A neonate with L-transposition of the great arteries with ventricular septal defect underwent complete repair using fresh autologous pericardium to close the ventricular septal defect as well as to reconstruct the neo pulmonary artery sinuses. Four months later, the child came back with right ventricular inflow obstruction related to aneurysmal pericardial patch, severe tricuspid regurgitation, and severe supra-valvular pulmonic stenosis. At reoperation, there was a redundant, aneurysmal pericardial patch densely adherent to the septal and posterior leaflets of the tricuspid valve, which was damaged. The pericardial patch was replaced, the pulmonary artery enlarged, and tricuspid valve repaired. Postoperative course was uneventful, but residual moderate tricuspid regurgitation required intensive medical treatment.
