Why the study?
Monomorphic VT is rare and challenging to manage in patients with HCM, with limited data on the utility of catheter ablation.
Does radiofrequency catheter ablation improve acute procedural success and freedom from recurrent VT in drug-refractory HCM patients?
Comparison
Radiofrequency catheter ablation for VT
Follow-up
18.3 ± 11.7 months

May support ablation for refractory monomorphic VT in HCM; extends sparse observational data but leaves practice implications open.

Does radiofrequency catheter ablation improve acute procedural success and freedom from recurrent VT in drug-refractory HCM patients?
Radiofrequency catheter ablation for ventricular tachycardia in patients with hypertrophic cardiomyopathy is associated with high acute procedural success and freedom from recurrent VT.
Garg et al. (2022) conducted a meta-analysis in Hypertrophic cardiomyopathy with ventricular tachycardia (n=68). Radiofrequency catheter ablation was evaluated on Acute procedure success (defined as noninducible for clinical VT) (95% CI 70.6-95.2). Radiofrequency catheter ablation for ventricular tachycardia in hypertrophic cardiomyopathy achieved an acute procedural success rate of 84.5% (95% CI 70.6-95.2%).
