Mapping the causes of ventricular tachycardia

Outcomes of Functional Substrate Mapping of Ventricular Tachycardia (Func-VT) - an International Propensity-matched Prospective Registry

Observational Mid and South Essex NHS Foundation Trust · NCT05708131

This study is testing a new ablation technique for ventricular tachycardia in people with heart disease to see if it is safer and more effective than the standard method.

What this trial studies

This international multicentre registry aims to evaluate the safety and effectiveness of a specific ablation technique for ventricular tachycardia (VT) in patients with ischaemic heart disease. Participants will be monitored before, during, and after the procedure, with follow-up assessments at 6 and 12 months to compare outcomes with a control group receiving standard ablation methods. The study will focus on mortality rates and the need for implantable cardioverter-defibrillator (ICD) therapies post-ablation.

Who should consider this trial

Good fit: Ideal candidates include patients with a history of ventricular tachycardia events and an ejection fraction of less than 40%.

Not a fit: Patients with contraindications to VT ablation or severe comorbidities may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved treatment outcomes and reduced mortality for patients with ventricular tachycardia.

How similar studies have performed: Previous studies have shown promise in similar ablation techniques, suggesting potential for success in this approach.
