Feasibility study for echocardiography‐guided lead insertion for permanent cardiac implantable electronic devices

Background Permanent cardiac implantable electronic devices (CIEDs) are traditionally implanted with the assistance of fluoroscopy. While clinically effective, this technique exposes both patients and providers to radiation which is associated with adverse health effects and represents an occupational hazard. In this study, we investigate the safety and feasibility of permanent CIED placement under the guidance of transthoracic echocardiography (TTE). There is also increasing interest in use of non‐fluoroscopic options for noninvasive cardiac electrophysiologic procedures. Methods Fifteen patients consecutively consented for initial implant of CIEDs, specifically dual chamber pacemakers (DCPM) and dual chamber implantable cardioverter defibrillators (DCICDs). Patients were excluded if they had previous implants, abandoned leads, or anatomic anomalies including congenital and known persistent left superior vena cava (PLSVC). We used TTE to guide and implant atrial and ventricular leads. Results Eleven patients received DCPMs and four patients received DCICDs. The procedure duration was 49.3 min for DCICD and 52.3 min for DCPM, p = .807. The average number of right atrial lead attempts was 1.6 for DCPMs and 1.8 for DCICD, p = .860. The average number of right ventricular lead attempts for DCPMs was 2.2 and 1.0 attempt for DCICDs, p = .044. There were no complications at 90‐day follow‐up. Conclusion We demonstrate the feasibility of TTE‐guided DCPM/DCICD implantation without use of fluoroscopy. We present this method as a safe alternative for permanent CIED placement that may reduce risk of radiation exposure and cost while maintaining safety and efficacy. No operators wore lead aprons during the procedure.
