Why the study?
Does radiofrequency catheter ablation improve LV dysfunction in a patient with PVC-induced cardiomyopathy?
Does radiofrequency catheter ablation improve LV dysfunction in a patient with PVC-induced cardiomyopathy?
Radiofrequency catheter ablation can successfully reverse PVC-induced cardiomyopathy in patients with a high burden of monomorphic PVCs.

Supports ablation for PVC-induced cardiomyopathy; hypothesis-generating from single case and requires prospective confirmation.
Premature ventricular complex (PVC)-induced cardiomyopathy is an underappreciated cause of left-ventricular (LV) dysfunction. The present report describes the case of an elderly man with a very high burden of monomorphic PVCs and LV dysfunction. Elimination of the left ventricular focus following radiofrequency catheter ablation resulted in reversal of cardiomyopathy.
