Key result
Minimally invasive surgical LV lead placement is linked to ~35 ms shorter QRS duration.
Why the study?
Transvenous insertion of left ventricular pacing leads via the coronary sinus is unsuccessful in 8-10% of patients requiring CRT, necessitating alternative approaches.
Does minimally invasive surgical LV lead placement safely and effectively accomplish cardiac resynchronization in patients with heart failure and failed transvenous lead insertion?
Observational (n=54)

Absolute Event Rate: 146% vs 181%
p-value: p=<0.001
Minimally invasive surgical LV lead placement is a safe and effective alternative for cardiac resynchronization therapy in patients with failed transvenous insertion.
No takes yet. Share an insight, caveat, or question.
May support surgical LV lead placement after failed transvenous CRT; hypothesis-generating and warrants randomized trials before practice change.
Corvera et al. (2007) conducted an observational in Congestive heart failure with interventricular conduction delay (n=54). Minimally invasive surgical left ventricular lead placement was evaluated on QRS duration (p=<0.001). Minimally invasive surgical left ventricular lead placement safely achieved cardiac resynchronization, significantly reducing QRS duration from 181 to 146 milliseconds (P<0.001).
