Key result
Epicardial left ventricular leads demonstrated a 5-year lead revision rate of 1.9% compared to 10.2% for transvenous leads, with both types showing significant improvements in heart failure symptoms.
Why the study?
Data comparing the durability and performance of transvenous coronary sinus leads versus epicardial left ventricular leads in cardiac resynchronization therapy are limited.
Do epicardial left ventricular leads provide comparable durability and efficacy to transvenous coronary sinus leads in patients receiving cardiac resynchronization therapy?

Do epicardial left ventricular leads provide comparable durability and efficacy to transvenous coronary sinus leads in patients receiving cardiac resynchronization therapy?
Absolute Event Rate: 1.9% vs 10.2%
Epicardial LV leads demonstrate excellent long-term durability with lower revision rates compared to transvenous leads, while providing comparable functional efficacy for CRT.
Bürger et al. (2019) conducted a cohort in Heart failure requiring cardiac resynchronization therapy (n=1,053). Epicardial left ventricular leads vs. Transvenous coronary sinus leads was evaluated on Lead revision rate at 5 years. Epicardial left ventricular leads demonstrated a 5-year lead revision rate of 1.9% compared to 10.2% for transvenous leads, with both types showing significant improvements in heart failure symptoms.
