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.
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…
Inclusion Criteria: * All patients older than 18 years of age * Patients with HFrEF that underwent BVP-CRT * Experienced CS lead failure, whether initial or recurrent, subsequently replaced with transthoracic epicardial lead placement or CSP * Underwent Medtronic, Boston Scientific, or Abbott lead placement Exclusion Criteria: * Patients younger than 18 years of age * Transthoracic epicardial lead placement or CSP performed as the initial approach or for other reasons than lead replacement * Those for which CRT no longer provides symptom relief or mortality benefit.
