Ring-Like Scar Architecture and Arrhythmic Outcomes of Patients With Nondilated Left Ventricular Cardiomyopathy Treated With Ventricular Tachycardia Ablation.
BACKGROUND Nondilated left ventricular cardiomyopathy (NDLVC) is characterized by an elevated arrhythmic burden and frequent presence of ring-like late gadolinium enhancement (RL-LGE) pattern. However, the arrhythmic substrate and outcomes after ventricular tachycardia (VT) ablations remain undefined. OBJECTIVES This...
