AI summary: who the study is looking for
From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.
The trial is looking for adults with heart failure from ischemic cardiomyopathy who are due to get a preventive ICD. It compares a catheter ablation for fast heart rhythms with medicines alone.
- Age
- 18 years or older, no upper age limit.
- Sex
- All sexes can join.
- Disease stage
- Ischemic cardiomyopathy with left ventricular ejection fraction (LVEF) of 35% or lower, and a candidate for a preventive ICD/CRT-D by ESC guidelines. They also need one or more of: MADIT-ICD Benefit Score above 75, past nonsustained ventricular tachycardia (NSVT), or PVCs of 10% or more.
- Earlier treatment
- Cannot already have an ICD or CRT-D. Cannot have had coronary revascularization or an ST-elevation heart attack in the past 3 months.
Main reasons for not taking part
- Already has an ICD or CRT-D
- History of sustained VT or VF
- Chronic kidney failure needing hemodialysis
- Heart attack (ST-elevation) or coronary revascularization in the past 3 months
- Currently pregnant or planning pregnancy soon

- Original description
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 full original descriptionShow less
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.

Exclusion: Participation in concurrent clinical trials without approval from the Coordination Center (observational registries are allowed with approval); History of sustained VT or VF; Chronic renal failure requiring hemodialysis; Existing ICD or CRT-D; Coronary revascularization within the past 3 months; ST-Elevation MI within the past 3 months; Currently pregnant or planning to become pregnant in the near future; Inability or unwillingness to adhere to the study protocol; Inability or unwillingness to provide informed consent for participation; Life expectancy < 1 year.
