Key result
The Quartet quadripolar left ventricular lead was successfully implanted in 96% of patients, with additional pacing vectors averting lead repositioning in 72% of cases with phrenic nerve stimulation.
Why the study?
Does a quadripolar left ventricular pacing lead provide stable pacing parameters and help overcome phrenic nerve stimulation in patients undergoing cardiac resynchronization therapy?

Does a quadripolar left ventricular pacing lead provide stable pacing parameters and help overcome phrenic nerve stimulation in patients undergoing cardiac resynchronization therapy?
The use of a quadripolar LV lead for CRT is associated with high implant success and allows for electronic reprogramming to overcome phrenic nerve stimulation without requiring physical lead revision.
Shetty et al. (2011) conducted an observational in Cardiac resynchronization therapy (n=28). Quartet model 1458Q quadripolar left ventricular lead was evaluated on Implant success rate. The Quartet quadripolar left ventricular lead was successfully implanted in 96% of patients, with additional pacing vectors averting lead repositioning in 72% of cases with phrenic nerve stimulation.
