Cardiac strains as a tool for optimization of cardiac resynchronization therapy in non-responders: a pilot study

Abstract

Approximately 30% of patients do not respond to implantation of Cardiac Resynchronization Therapy – Defibrillators (CRT-D). The aim of this study was to investigate the potential for cardiac strain speckle tracking to optimize the performance of CRT-D in non-responding patients.
