Long‐term follow‐up of patients with a quadripolar active fixation left ventricular lead: An Italian multicenter experience

摘要

Abstract Introduction Left ventricular (LV) lead optimal positioning is one of the most important determinants of cardiac resynchronization therapy (CRT) success. LV quadripolar active fixation (QAF) leads have been designed to ensure stable LV pacing in the target area and reduce the likelihood of phrenic nerve stimulation (PNS). The aim of this analysis is to compare performances, safety, and clinical outcomes of QAF with those of quadripolar passive fixation leads?(QPL) and bipolar active fixation (BAF) leads in a real‐world cohort of CRT patients. Methods and Results This retrospective analysis compared the procedure and follow‐up data of 117 QAF included in the One Hospital ClinicalService project from nine?Italian hospitals with two historical cohorts of 261 BAF and 124 QPL.?QAF enabled basal pacing more frequently than QPL (24.1 vs. 6.5, p?
