| Περιγραφή: | BACKGROUND: The Subcutaneous implantable cardioverter-defibrillator (S-ICD) has shown favorable outcomes in large registries with broad inclusion criteria. The cohorts reported had less heart disease and fewer co-morbidities than standard ICD populations. OBJECTIVE: The purpose of this study is to characterize acute performance for primary prevention patients with an ejection fraction (LVEF) ≤35% (primary prevention≤35%). METHODS: Primary prevention ≤35% patients with no prior documented sustained ventricular tachycardia (VT), pacing indication, end-stage heart failure, and/or advanced renal failure were prospectively enrolled. Analyses included descriptive statistics, Kaplan-Meier time to event, and multivariable logistic regression. RESULTS: In 1112 of 1116 patients, an S-ICD was successfully implanted (99.6%). Predictors for longer procedure time included three-incision technique, higher body mass index (BMI), performing defibrillation testing (DFT), imaging, younger age, black race, and European vs North American centers. Patients undergoing DFT (82%) were successfully converted 99.2% (94.3% converting at ≤65J). Higher BMI was predictive of failing DFT at ≤65J. The rate of 30-day freedom from complications was 95.8%. Most complications involved post-op healing (45%) or interventions after DFT or impedance check (19%). CONCLUSIONS: The procedural outcome data of UNTOUCHED reinforce that S-ICD therapy has low perioperative complication rates and high conversion efficacy of induced ventricular fibrillation, even in a higher risk cohort with low LVEF and more co-morbidities than previous S-ICD studies. Higher BMI warrants more careful attention to implant technique. |
