Does radiofrequency ablation of frequent isolated PVCs improve left ventricular dysfunction in patients with PVC-induced cardiomyopathy?
This case provides the first evidence that frequent isolated PVCs can induce a reversible form of cardiomyopathy that resolves with radiofrequency ablation.
Tachycardia-induced cardiomyopathy is a well-recognized and reversible condition, but left ventricular dysfunction due to frequent isolated premature ventricular complexes (PVCs) has not been reported. We observed resolution of dilated cardiomyopathy in a patient after a focal source of PVCs was eliminated by radiofrequency ablation. In a subset of patients with heart failure, PVC-induced cardiomyopathy may be a potentially reversible cause of left ventricular dysfunction.
