研究概览
简要总结
This prospective, multicenter, open-label, randomized-controlled trial compares two treatment strategies in high-risk ischemic cardiomyopathy (ICM) patients referred for primary ICD implantation. Participants will be randomized to receive either prophylactic VT ablation within three months of ICD implantation or continued medical management. The primary objective is to assess the efficacy of preventive VT ablation versus medical management in reducing VT arrhythmia burden.
详细描述
This study aims to assess the impact of prophylactic catheter-based ventricular tachycardia (VT) ablation compared to medical management in high-risk patients with ischemic cardiomyopathy (ICM) undergoing primary implantable cardioverter defibrillator (ICD) implantation. The primary outcome measure is the burden of VT arrhythmias (VTA), defined as the total number of VT events, one year post-ICD implantation. The hypothesis suggests that employing VT ablation with high-density electroanatomic mapping (EnsiteTM) will significantly reduce both treated and monitored VT episodes. The study will randomize 62 participants in a 1:1 ratio across 20 experienced sites in Europe.
