About this study
Official title: Primary Preventive Ventricular Tachycardia Ablation In High-Risk Patients Who Receive A Prophylactic Implantable Cardioverter Defibrillator (PRIMARY PREVENT-VT TRIAL)
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.
Read the detailed description
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Prophylactic Catheter-based VT AblationProcedure or surgery
Prophylactic Catheter-based VT Ablation refers to a treatment strategy where participants undergo a procedure known as catheter-based ventricular tachycardia (VT) ablation shortly after receiving their primary implantable cardioverter defibrillator (ICD).
| Study group | Role | What they receive |
|---|---|---|
| Prophylactic Catheter-based VT Ablation | Experimental | Subjects receive catheter-based ventricular tachycardia (VT) ablation within 3 months of primary ICD implantation. Receives: Procedure: Prophylactic Catheter-based VT Ablation |
| Continued Medical Management | No intervention | Subjects undergo continued medical management after primary ICD implantation without prophylactic VT ablation. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Total Number of VT Arrhythmia Events in High-Risk Patients with Ischemic Cardiomyopathy (ICM) After Primary ICD Implantation: Comparison of Preventive Catheter-Based VT Ablation Versus Medical Management.
Evaluating the impact of preventive catheter-based VT ablation versus medical management on the total number of VT arrhythmia events in high-risk patients with ischemic cardiomyopathy (ICM) after primary ICD implantation.
Measured: One year following ICD implantation.
Secondary outcomes (1)
Impact of Preventive VT Ablation on Healthcare Utilization, assessed using the mean rate of events per arm.
Assessing whether preventive VT ablation compared to medical management reduces healthcare resource utilization in high-risk patients with ICM after primary ICD implantation. Healthcare resource utilization will be quantified by averaging planned and unplanned in-office visits, urgent care or emergency room visits, hospitalizations, repeat ablations, or mortality per arm. Data on healthcare utilization will be collected at all follow-up visits (months 3, 6, and 9) and at the end-of-study visit. Analysis will be conducted using a t-test for comparison.
Measured: One year following ICD implantation.
