Who could benefit from this research

Could help

Adults with ventricular tachycardia undergoing catheter ablation who have implantable cardioverter-defibrillators.

Less likely to help

Patients not undergoing VT ablation or without suspected scar-related VT may not benefit.

What this research studies

This project aims to improve VT ablation by using advanced 3D imaging techniques to better visualize heart tissue and guide catheter therapy. It focuses on identifying epicardial and intramural scars that conventional mapping tools may miss, potentially reducing procedure time and increasing success. Patients with VT and ICDs could benefit from more accurate planning and safer ablation with reduced radiation exposure. The study builds on prior imaging work with CMR and CT to create clearer, actionable maps for clinicians.

Why it matters

Potential benefit: If successful, patients could experience higher VT ablation success, fewer ICD shocks, and improved quality of life.

How similar studies have gone: Prior imaging-guided ablation work shows promise but wideband 3D integration for planning is still being tested.
