Coronary Vein Rupture during Venoplasty for LV Lead Placement

Abstract

Coronary vein rupture is a potential complication of venoplasty for LV lead placement. Vein rupture in a patient with a virgin pericardium would be anticipated to have a profound hemodynamic impact from bleeding into the pericardial space. This report describes an elderly woman with a virgin pericardial space who underwent cardiac resynchronization therapy (CRT). Venoplasty of a lead limiting venous stenosis was performed on the lateral coronary vein. The stenosis was unresponsive to a standard noncompliant balloon with side wire. When the inflation pressure was increased beyond the rated burst pressure the balloon ruptured, perforating the vein. We describe our experience in successfully placing the left ventricular lead safely despite the problems arising from these circumstances.
