Abstract

Cardiac resynchronization therapy (CRT) is an established option for select patients with systolic heart failure. Nonresponse to CRT remains a significant problem. We present five patients who were CRT nonresponders and discuss the conventional and nonconventional approaches employed to achieve CRT benefit.

Keywords: Cardiac resynchronization therapy; catheter ablation to enhance CRT; multipoint pacing; multisite pacing; permanent His-bundle pacing.
