Clinical and procedural outcome of patients implanted with a quadripolar left ventricular lead: early results of a prospective multicenter study

Recent studies suggest that cardiac resynchronization therapy (CRT) with a quadripolar left ventricular (LV) lead results in low rates of dislocation and phrenic nerve stimulation (PNS) acutely and at short-term follow-up. Confirmation of these results by long-term observational studies is needed
