Background. Cardiac resynchronization therapy has been shown to be effective in reducing symptoms and mortality in heart failure patients. However, very few is known about the importance of the left ventricular pacing site.
Design. Single-blind, monocentric, randomized cross-over study comparing 11 left ventricular pacing sites in a random order.
Intervention. Left ventricular DDD pacing on 11 ventricular sites, prior to the implantation. At each pacing site, a control hemodynamics will be obtained in AAI pacing at the same pacing rate. At each pacing site, 2 AV delays, a short and a long one, will be assessed.
Eligibility criteria. Patients referred for cardiac resynchronization therapy for heart failure
Outcomes. Hemodynamic measures using pressure-volume catheters.
