What does this research mean for the field?

In heart failure patients, the correlation between intraventricular mechanical and electrical dyssynchrony is weak, and the absence of intraventricular dyssynchrony in a subset of patients with prolonged QRS duration may explain non-response to cardiac resynchronization therapy. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

Overview

Weak QRS-mechanical dyssynchrony correlation may underlie CRT nonresponse; leaves open whether mechanical assessment improves selection beyond QRS criteria.

Population

123 consecutive patients with severe heart failure (LVEF < 35% and NYHA class III-IV)

Outcome

Prevalence of interventricular and intraventricular dyssynchronysurrogate

The weak correlation between electrical (QRS duration) and mechanical (intraventricular) dyssynchrony may explain why a significant fraction of patients with standard CRT indications are nonresponders.
