Ablation Index-guided treatment for ventricular tachycardia in heart disease patients
Official title: Ablation-Index Guided Scar-Mediated Ventricular Tachycardia Ablation in Patients With Ischemic Cardiomyopathy (AIM-VT) - a Prospective Single-Blinded, Multicenter Randomized Controlled Trial
Run by Rush University Medical Center · NCT06138873 · Data updated 2026-11-12
This study tests whether using a new technology to guide heart procedures can help people with heart disease and fast heartbeats feel better and have fewer problems later on compared to standard methods.

Is this trial a fit for you?
✓Likely a good fit
Ideal candidates for this study are adults aged 18 and older with ischemic cardiomyopathy and documented sustained scar-related monomorphic ventricular tachycardia.
✕Probably not a fit
Patients with predominantly PVCs, recent myocardial infarction, severe mitral regurgitation, or those with non-ischemic VT substrate may not benefit from this study.

What this trial studies
This clinical trial investigates the effectiveness of Ablation Index (AI)-guided catheter ablation for treating ventricular tachycardia in patients with ischemic cardiomyopathy. The study compares outcomes of AI-guided ablation to traditional methods without AI guidance. By utilizing advanced technology to monitor lesion quality and depth during the procedure, the trial aims to improve patient outcomes and reduce the recurrence of arrhythmias. The research is particularly focused on patients with structural heart disease and prior myocardial infarction.
Why it matters
Potential benefit: If successful, this approach could lead to better management of ventricular tachycardia, reducing the risk of arrhythmia recurrence and improving quality of life for patients.
How similar studies have gone: Previous studies have shown success with AI-guided approaches in other types of arrhythmias, but this specific application for ventricular tachycardia in patients with structural heart disease is novel.
