Key result
Late gadolinium enhancement cardiac magnetic resonance is a potentially useful technique for discriminating between reversible PVC-induced cardiomyopathy and primary left ventricular cardiomyopathy with irreversible scar.
LGE CMR is a valuable tool to differentiate reversible PVC-induced cardiomyopathy from primary structural cardiomyopathy with irreversible scar, which impacts the choice between catheter ablation and ICD implantation.
May inform PVC-cardiomyopathy etiology assessment; leaves open prospective validation before clinical use.
Premature ventricular contractions (PVCs) are usually regarded as benign in the absence of structural heart disease. However, frequent PVCs can lead to depressed LV function, called PVC-induced cardiomyopathy and can be reversible after suppression of PVCs. On the other hand, PVCs can be a part of underlying structural heart disease and may be linked to increased risk of sudden death. In this work, we reviewed the current literature on PVC-induced cardiomyopathy based on a case presentation.

Yalın et al. (2017) conducted a review in Premature ventricular contractions and cardiomyopathy (n=1). Late gadolinium enhancement cardiac magnetic resonance (LGE CMR) and catheter ablation was evaluated. Late gadolinium enhancement cardiac magnetic resonance is a potentially useful technique for discriminating between reversible PVC-induced cardiomyopathy and primary left ventricular cardiomyopathy with irreversible scar.
