Radiofrequency ablation achieved 84.9% acute success and 6.6% 6-month recurrence in idiopathic PVC patients, with age predicting acute success and low complication rates.
Does radiofrequency ablation provide acute procedural success and safety in patients with idiopathic premature ventricular contractions?
Radiofrequency ablation is a highly effective and safe treatment for idiopathic PVCs, achieving nearly 85% acute success with low short-term recurrence.
Absolute Event Rate: 0% vs 0%
Premature ventricular contractions (PVCs) are common arrhythmias that may impair quality of life and lead to PVC-induced cardiomyopathy. Radiofrequency ablation (RFA) has emerged as an effective treatment option for symptomatic and drug-refractory idiopathic PVCs, yet real-world data remain limited. This retrospective single-center study included 53 patients who underwent RFA for idiopathic PVCs between December 2022 and June 2024. Demographic, clinical, and procedural data were analyzed. Acute procedural success, 6-month recurrence, and complications were evaluated according to PVC localization. The mean age of the cohort was 52.1 ± 12.9 years, and 62.3% were female. Acute procedural success was achieved in 84.9% of patients. The most frequent origin was the right ventricular outflow tract (60.4%), followed by the left ventricle (26.4%), coronary cusp (11.3%), and para-Hisian region (1.9%). At 6-month follow-up, recurrence occurred in 6.6% of patients. Complications included 2 cases of steam pop with mild pericardial effusion and 2 cerebrovascular events, both with complete recovery. Age was identified as an independent predictor of acute procedural success ( P < .05). RFA is a safe and effective treatment for idiopathic PVCs, providing high acute success and low recurrence rates. Early intervention in symptomatic or drug-refractory patients may improve outcomes and help prevent PVC-induced cardiomyopathy.
