Transvenous Implantation of a Coronary Sinus Lead for Left Ventricular Pacing After Cutting Balloon Angioplasty

Abstract

We describe a patient in whom a localized proximal vein stenosis at the only possible target vein precluded placement of a coronary sinus lead for left ventricular (LV) pacing. After multiple attempts to perform venoplasty with both compliant and noncompliant balloons, a cutting balloon relieved the obstruction, and an LV pacing lead was successfully placed in the midportion of this lateral vein.
