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.

Refining ARVC Risk Stratification: Does Left Ventricular Late Gadolinium Enhancement Add Incremental Value to Clinical Risk Calculators?

By MedXY 03/03/2026

A multi-center study of 385 ARVC patients reveals that while Left Ventricular Late Gadolinium Enhancement (LV LGE) correlates with ventricular arrhythmias, it fails to provide incremental prognostic value beyond the established ARVC risk calculator, reinforcing the calculator's role as the primary tool for clinical decision-making.

Low-Dose Rivaroxaban Fails to Significantly Reduce Left Ventricular Thrombosis in Anterior STEMI: Results of the APERITIF Trial

By MedXY 02/27/2026

The APERITIF randomized clinical trial found that adding low-dose rivaroxaban to dual antiplatelet therapy (DAPT) did not significantly reduce the incidence of left ventricular thrombus at one month in anterior STEMI patients, while significantly increasing the risk of minor bleeding events.

Redefining Severity in Tricuspid Regurgitation: Why CMR-Derived Regurgitant Fraction and Liver Mapping Are the New Prognostic Gold Standards

By MedXY 12/25/2025

A landmark study in Circulation reveals that CMR-quantified tricuspid regurgitant fraction (TRF) ≥20% significantly increases mortality risk, while liver extracellular volume (L-ECV) mapping provides a novel, potent biomarker for systemic congestion and right heart failure outcomes.
