Key result
Catheter ablation successfully treats two tachycardia circuits in an HCM patient with electrical storm.
Why the study?
Catheter ablation of VT in structural heart disease reduces ICD discharges and improves survival, motivating case description in hypertrophic cardiomyopathy.
Case Report (n=1)
Catheter ablation successfully identified and targeted two tachycardia circuits in a patient with hypertrophic cardiomyopathy presenting with an electrical storm.
Highlights ablation feasibility in refractory HCM storm; leaves open need for prospective validation.
Catheter ablation of ventricular tachycardia (VT) in structural heart disease is a useful strategy to reduce the discharges of implantable cardioverterdefibrillators (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.

Jorge Gómez-Flores (2023) conducted a case report in Hypertrophic cardiomyopathy with ventricular tachycardia electrical storm (n=1). Catheter ablation (radiofrequency) was evaluated on Identification of tachycardia circuits and application of radiofrequency. Catheter ablation successfully identified and treated two tachycardia circuits using radiofrequency in a 30-year-old female with hypertrophic cardiomyopathy presenting with an electrical storm.
