Summary

Impact of intraventricular electrical activation in resynchronization therapy. We seek to evaluate the impact of Cardiac Resynchronization Therapy (CRT) on electrical activation of the Left Ventricle (LV). The first goal of the study is to evaluate if CRT is able to decrease the heterogeneity of LV activation in heart failure patients. A second goal is to evaluate the electrical determinant of clinical response to CRT using invasive and non-invasive mapping technology.

Conditions

Interventions

DEVICE

Invasive mapping with CARTO3 system and Non-Invasive mapping with CardioInsight Atlas EC Mapping system

Day 1: CRT device is implanted under general anesthesia in a conventional fashion. The coronary sinus leads will be implanted guided by the acute hemodynamic response (+(dP/dt)max) using a RADI guide wire. After device implantation, a steerable mapping catheter will be inserted in the Left Ventricle (LV) cavity to build a tridimensional activation map of the LV. This map will be obtained with and without CRT. From these maps different parameters describing LV activation will be measured and compared between patients with and without CRT. Day 5±2: A non-invasive map of the LV will be recorded with the CardioInsight ® system with and without CRT. The same parameters will be measured and compared with those obtained with invasive mapping.
