Abstract

Purpose of review

To describe the growing evidence that a maximal biventricular pacing is needed to gain the maximal benefits from cardiac resynchronization therapy (CRT).

Recent findings

Even small gains in the biventricular (BIV) pacing percentage are clinically important both to prevent acute heart failure and, more importantly, to improve survival.

Summary

Every effort should be made in all patients receiving CRT to approach 100% BIV pacing by a correct device programming, a correct pharmacologic regimen and atrioventricular nodal ablation in atrial fibrillation patients.
