Summary

This is a prospective, randomized, controlled trial to investigate the efficacy of radiofrequency catheter ablation (RFCA) combined with guideline-directed medical therapy (GDMT) compared to GDMT alone in patients with polymorphic ventricular tachycardia (PMVT) and coexisting heart failure (HF). The study aims to evaluate whether the addition of RFCA can lead to superior improvements in cardiac function, clinical outcomes, and serum biomarkers at a 6-month follow-up.

Conditions

Interventions

DEVICE

Radiofrequency Catheter Ablation

An invasive procedure performed under local anesthesia. An electroanatomic mapping system (CARTO 3) was used to identify the arrhythmogenic substrate of the PMVT. Radiofrequency energy was delivered via an irrigated-tip catheter (30-35 W, 43°C, 17 mL/min saline irrigation) to ablate the target sites. The procedural endpoint was the non-inducibility of the clinical arrhythmia. Post-procedure, patients were prescribed amiodarone.

DRUG

Guideline-Directed Medical Therapy (GDMT)

Standard medical therapy for heart failure, including spironolactone (20 mg once daily), metoprolol succinate (25 mg twice daily), and sacubitril/valsartan (50 mg twice daily). Doses were titrated according to patient tolerance and clinical guidelines.
