Bear track hypothesis in outcomes of ventricular tachycardia ablation: Risk factor or risk marker or both for heart failure?

Abstract

We read the article with great interest by Sharma et al 1 about ventricular tachycardia (VT) and heart failure (HF) that are the most common cause of 30-day readmission after initial VT ablation. Authors noted a high readmission 30-day rate as 16.3%, 1 and these represent a high-risk VT patient population with advanced HF, and also limitations in current technologies, ablation techniques, and understanding of pathophysiological mechanisms. 2,3 Furthermore, VT ablation patients seem likely to be at a higher risk of complications due to underlying advanced HF and comorbidities. 1 We want to address some points that
