Conduction System Vs Surgical Left Ventricular Epicardial Pacing For Coronary Sinus Lead Failure
Kansas City Heart Rhythm Research Foundation
Summary
This a single-center, retrospective, observational study of patients that undergo coronary sinus(CS) lead revision, comparing epicardial lead placement to coronary sinus pacing(CSP) in those that had lead failure.
Description
Cardiac resynchronization therapy with defibrillator(CRT-D) improves quality of life, functionality, and even mortality for select patients with severe heart failure with reduced ejection fraction (HFrEF). It traditionally consists of three leads placed endovascularly into the right atrium, right ventricle, and left ventricle (LV) \[typically placed into the CS\], known as biventricular pacing resynchronization (BVP-CRT), respectively, from which electrical stimulation enables improved cardiac synchrony. Nonetheless, the placement of a CRT-D is not without risks. Lead-related complication is h…
