Summary

AVA CONDUCT is a prospective, multicenter, randomized study with single blinding, comparing left bundle branch area (LBBA) pacing with right ventricular (RV) pacing following AV node ablation in terms of clinical, functional, and electrophysiological outcomes. The primary hypothesis is that pacing-induced cardiomyopathy, defined as a decrease in LVEF by 10% or more from baseline to an absolute value below 50%, occurs significantly more frequently in patients receiving RV pacing compared with LBBA pacing. Secondarily, LBBA pacing is expected to maintain comparable procedural safety while providing better cardiac function, resulting in improved quality of life and functional capacity compared with conventional RV pacing.

Conditions
