Upgrade to cardiac resynchronization therapy benefits heart failure patients with pacing

Upgrade to cardiac resynchronization therapy with a defibrillator (CRT-D) reduces morbidity and mortality and improves left ventricular (LV) reverse remodeling compared to an implantable cardioverter-defibrillator (ICD) in select patients with heart failure and reduced ejection fraction (HFrEF) and intermittent or permanent right ventricular (RV) pacing, according to late breaking research presented in a Hot Line session August 26 at ESC Congress 2023.
