PVC-induced cardiomyopathy is a distinct, treatable condition where early detection and suppression of ectopic burden can lead to complete functional recovery and prevention of heart failure progression.
Premature Ventricular Complexes (PVCs) are among the most frequent ventricular arrhythmias observed in daily cardiology practice. Although often benign, sustained high ectopic activity can result in left ventricular dysfunction known as PVC-induced Cardiomyopathy (PVC-CMP), a condition that is frequently reversible when the arrhythmia is effectively suppressed. The underlying mechanisms are multifaceted, involving electromechanical dyssynchrony, contractile inefficiency, abnormal calcium cycling, neurohormonal activation, and progressive structural remodeling. The likelihood of developing PVC-CMP varies among individuals and is influenced by electrophysiological and structural factors. Diagnosis relies on prolonged rhythm monitoring, comprehensive multimodality imaging, and demonstration of ventricular recovery after reducing the ectopic burden, which, in turn, confirms causality. Over the past decade, major advances in electrocardiographic mapping, cardiac imaging, and ablation therapy have transformed this field, demonstrating excellent efficacy and safety profiles. In parallel, artificial intelligence and computational mapping are emerging as powerful tools for prediction and procedural guidance. Recognition of PVC-CMP as a distinct, treatable cardiomyopathy highlights the importance of early detection and individualized therapy, offering the prospect of complete functional recovery and the prevention of heart failure progression.
