Key result
The Quartet LV lead demonstrated stable electrical performance, a 95.5% implant success rate, a 3.5% dislodgement rate, and enabled noninvasive elimination of phrenic nerve stimulation in all cases.
Why the study?
Does the Quartet quadripolar LV lead provide stable electrical performance and allow noninvasive resolution of phrenic nerve stimulation in patients requiring CRT-D?

May facilitate CRT-D implantation with PNS resolution; leaves open randomized confirmation of long-term outcomes.
Does the Quartet quadripolar LV lead provide stable electrical performance and allow noninvasive resolution of phrenic nerve stimulation in patients requiring CRT-D?
The quadripolar Quartet LV lead demonstrates stable electrical performance and allows for noninvasive resolution of phrenic nerve stimulation through multiple pacing vectors.
Tomassoni et al. (2013) studied Standard indications for CRT-D (n=170). Quartet left ventricular (LV) lead was evaluated on Electrical performance and presence of phrenic nerve stimulation (PNS). The Quartet LV lead demonstrated stable electrical performance, a 95.5% implant success rate, a 3.5% dislodgement rate, and enabled noninvasive elimination of phrenic nerve stimulation in all cases.
