Understanding Scar Evolution: How Post-Ablation Cardiac MRI Predicts Long-Term Outcomes in Ventricular Tachycardia

By MedXY 03/07/2026

The PAM-VT 2 study reveals that cardiac MRI (LGE-CMR) performed 3 to 6 months after ventricular tachycardia ablation can accurately predict long-term recurrence risks by analyzing scar stability and conducting channels.

High-Voltage Focal Pulsed Field Ablation Achieves Transmurality and 98% Reduction in Scar-Related Ventricular Tachycardia

By MedXY 01/18/2026

The first-in-human VCAS trial demonstrates that high-voltage focal pulsed field ablation (PFA) safely delivers transmural lesions in thick ventricular scar tissue, significantly reducing ventricular tachycardia burden by 98% in high-risk patients with ischemic and non-ischemic substrates.
