Epicardial Ventricular Tachycardia Ablation (original) (raw)

The paper discusses the evolution of catheter ablation procedures from endocardial to epicardial approaches for treating ventricular tachycardia (VT). It emphasizes the importance of understanding epicardial substrates and highlights the challenges associated with identifying the epicardial arrhythmia focus. The findings suggest that epicardial ablation may improve treatment outcomes in selected patients, particularly those with nonischoric cardiomyopathy, despite the necessity for careful pre-operative evaluations and experienced operators due to potential complications.
