Key result
Dual-energy contact force-sensing catheter ablation successfully treats refractory VT in a patient with LVAD.
Why the study?
Patients with LVAD therapy for advanced HF remain at high risk for ventricular arrhythmias, and catheter ablation of VT may be a reasonable strategy when antiarrhythmic drugs fail.

May offer ablation option for refractory VT in LVAD patients after drug failure; leaves open need for prospective trials before wider adoption.
Left ventricular assist device(LVAD) therapy is an established treatment for patients with advanced heart failure(HF)1. This population remains at high risk for ventricular arrhythmias, which are associated with considerable morbidity and mortality2. Catheter ablation (CA) of ventricular tachycardia(VT) in these high-risk patients may be a reasonable strategy, when antiarrhythmic drugs(AADs) fail3.

Lyan et al. (2026) conducted a case report in Ventricular tachycardia in a patient with a left ventricular assist device and advanced heart failure (n=1). Ventricular tachycardia ablation using a novel dual-energy contact force-sensing catheter was evaluated. Catheter ablation using a novel dual-energy contact force-sensing catheter was described in 1 patient with a left ventricular assist device and drug-refractory ventricular tachycardia.
