Right Ventricular Defibrillation Lead Select Site Study

October 30, 2007 updated by: Associates in Cardiology, PA
This study will compare single coil right ventricular defibrillation leads for implanted cardioverter/defibrillators (ICDs) in the apical and high septal locations. It is hypothesized that RV septal positions are at least as good as apical positions using formally measured defibrillation thresholds(DFTs), and that they may have long term advantages in reducing left ventricular dysfunction.

Detailed Description

The new studies "Right Ventricular Lead/Select Site Registry" and "Right Ventricular Lead/Select Site Registry: Acute Study" are studies designed to look at alternate lead locations for defibrillation leads for ICDs. The registry is designed to capture data from patients who have already undergone implant, so as to be able to publish long term data on defibrillation thresholds, pacing thresholds and left ventricular function. This will include both patients from the acute study, and those patients in whom leads have already been placed, and the exact lead location is known. The acute study is designed to directly compare defibrillation thresholds in the apical location versus the interventricular septal location for defibrillation leads. This study involves a direct comparison of two different sites in the same patient; using defined criteria for implant location (see protocol). The acute study is anticipated to enroll 34 patients, but the registry to collect ongoing data will be larger, encompassing previously implanted patients, with an expected sample size of 61 total in the registry for data collection.
