New S-ICD defibrillator a safety net for cardiac patients
The purpose of this study was to describe the technical feasibility of combining single chamber icd pacing S-ICD with other cardiac implantable electronic devices CIEDsincluding pacemakers with transvenous or epicardial electrodes.
We also provide the first experience of combining an S-ICD with catheter-based therapies, including cardiac contractility modulation CCM and vagus nerve stimulation. In all patients, intraoperative S-ICD testing, crosstalk tests, and postoperative ergometric testing were performed.
In all 10 patients, device implantations were successfully performed without complications. Mean follow-up was nearly 17 months. S-ICD testing and crosstalk testing before and during exercise enabled device programming across a single chamber icd pacing range of test conditions and was associated with no subsequent evidence of adverse device interaction.
None of the devices required permanent inactivation or removal, and no patient received an inappropriate shock. In suitable patients, combining an S-ICD with CCM or pacemaker may provide an acceptable means to reduce the number of transvascular leads.
