Removal of a constricting epicardial pacemaker lead in a single-ventricle patient improved ventricular function by relieving mechanical compression and restoring AV synchrony.
Epicardial pacemaker leads can cause mechanical cardiac strangulation and ventricular dysfunction, which may be reversible upon lead removal and restoration of atrioventricular synchrony.

Abstract We report a 24-year-old male with functional single ventricle who developed ventricular dysfunction associated with strangulation by a previous epicardial pacemaker lead. During conversion to dual-chamber pacing, the constricting ventricular lead was removed, with intraoperative echocardiography demonstrating improvement in apical contraction. Relief of mechanical compression, together with restoration of atrioventricular synchrony, likely contributed to the recovery of ventricular function.
