Key result
Catheter ablation for frequent premature ventricular contractions yields response rates of 60-88% and improves left ventricular ejection fraction in 47-100% of successful cases.

Supports ablation consideration in PVC cardiomyopathy; extends observational data but leaves open RCT confirmation of LVEF benefit.
Does catheter ablation improve left ventricular function in patients with PVC-induced cardiomyopathy?
Frequent PVCs can cause left ventricular dysfunction, and catheter ablation is an effective therapy that can improve left ventricular ejection fraction.
Lee et al. (2015) conducted a review in Premature ventricular contraction-induced cardiomyopathy. Catheter ablation was evaluated. Catheter ablation for frequent premature ventricular contractions yields response rates of 60-88% and improves left ventricular ejection fraction in 47-100% of successful cases.
