Positive Response to Cardiac Resynchronization Therapy Reduces Arrhythmic Events After Elective Generator Change in Patients with Primary Prevention CRT-D

摘要

Arrhythmic Outcome After CRT-D Device Replacement. Introduction: Cardiac resynchronization therapy (CRT) and implantable cardioverter-defibrillators (ICD) are effective therapies for heart failure (HF) patients with cardiac dyssynchrony. Patients receiving primary prevention CRT-defibrillator that positively remodel might no longer qualify for ICD indication due to CRT-induced left ventricular ejection fraction (LVEF) improvement. We aimed to evaluate the outcome of CRT-D patients at the time of device replacement (DR).
