Identification of Circuits in Ventricular Tachycardia Ablation inHypertrophic Cardiomyopathy: A Case Report

Abstract

Catheter ablation of ventricular tachycardia (VT) in structural heart disease is a useful strategy to reduce the discharges of implantable cardioverter-defibrillators (ICDs) and improve patient survival.

We present the case of a 30-year-old female, with hypertrophic cardiomyopathy, carrier of ICD as primary prevention, who presented to the emergency department with an electrical storm and multiple shocks (Figure 1), which is why she was taken to catheter ablation. In the procedure, two tachycardia circuits were identified, and radiofrequency was applied.
