His bundle pacing: 10-years follow-up

Abstract Funding Acknowledgements Type of funding sources: None. Background His bundle pacing (HBP) ensures a physiologic ventricular activation and can prevent pacing-induced cardiomyopathy. Published experiences confirm good clinical results on short-term follow-up. Data long-term follow-up are still lacking Objective analyze technical HBP in an unselected population during very Methods We retrospectively analyzed 370 patients (mean age 75±8 years; 221 males) with standard indication for implanted from 2003 to 2012. In all cases the implant was performed by lumenless fixed screw 3830 Medtronic deflectable sheath C304. 52% selective-HBP obtained while 48% non selective-HBP. The indications were AV block 51%, sinus node disease 22%, atrial fibrillation slow rate 25%, heart failure 2%. Ischemic cardiopathy found 84 (29%); hypertension 317 (86%) diabetes 108 (29%).
