Abstract

Tetralogy of Fallot was repaired previously in a preschooler through right ventriculotomy, providing excellent exposure for ventricular septal defect closure and right ventricular outflow tract obstruction relief. Herein, we describe the preschooler as a 50-year-old man with untreated atrial septal defect found at pulmonary valve replacement in the remote period after tetralogy of Fallot repair. It was inferred intraoperatively that the previous tetralogy of Fallot was repaired only through right ventriculotomy, and atrial septal defect closure was performed together with pulmonary valve replacement.

Abstract

A 5-year-old girl has a history of epicardial VVI-pacemaker implantation due to congenital heart block at the age of 2 months. Five years later, she developed heart failure at the same time of battery depletion. The chest X-ray indicated the loop formation of the epicardial leads and the echocardiogram demonstrated paradoxical movement of ventricles. The 3-dimensional computed tomography finally revealed strangulation of biventricular apex caused by loop of the leads. She underwent reoperation. Cardiac strangulation was relieved by total removal of the loop and repositioning of right atrial and ventricular electrodes in a gentle curve of the leads. She was discharged and doing well. Cardiac strangulation is a rare, but it can be lethal. Therefore epicardial pacemaker leads should not be positioned around the ventricle with excessive redundancy.
