Novel quadripolar LV lead allows 10 pacing configurations to optimize vectors and avoid phrenic stimulation.
Case Report (n=1)
The use of a quadripolar LV lead in cardiac resynchronization therapy provides programming flexibility to optimize pacing around myocardial scars and avoid phrenic nerve stimulation without repositioning.
May offer CRT programming flexibility around scar; hypothesis-generating and should not yet change practice.
We present a case of a 76-year-old man with ischemic cardiomyopathy. Cardiac magnetic resonance imaging demonstrated severe left ventricular (LV) impairment with possibility of scar formation. Cardiac resynchronization therapy was employed with the aid of a novel quadripolar LV lead. The quadripolar LV lead can be programmed for 10 different pacing configurations, allowing the electrophysiologist freedom to optimize the vector around scar and also avoid phrenic nerve stimulation without the requirement of LV lead repositioning.

Hussain et al. (2011) conducted a case report in Ischemic cardiomyopathy (n=1). Cardiac resynchronization therapy with a quadripolar left ventricular lead was evaluated. A novel quadripolar left ventricular lead allowed for 10 different pacing configurations in a 76-year-old man with ischemic cardiomyopathy, optimizing the vector around scar and avoiding phrenic nerve stimulation.
