Treatment of Premature Ventricular Contractions: A Review of Medical Therapy, Catheter Ablation, and Emerging Treatments.

Premature ventricular contractions (PVCs) are common arrhythmia encountered in patients with and without structural heart disease. Although often benign and asymptomatic, they may also cause palpitations, exercise intolerance, presyncope, and reduced quality of life, and in some patients can contribute to PVC-induced cardiomyopathy or trigger malignant ventricular arrhythmias. Their clinical significance depends on symptom burden, PVC frequency, ventricular function, and the presence of underlying myocardial disease. Diagnostic evaluation includes electrocardiography, ambulatory rhythm monitoring, echocardiography, exercise testing, and cardiac magnetic resonance imaging for tissue characterization and risk stratification. Management ranges from reassurance and lifestyle modification to pharmacologic therapy and catheter ablation. Beta-blockers and nondihydropyridine calcium channel blockers remain common first-line options, whereas antiarrhythmic drugs may be considered in carefully selected patients. Catheter ablation is an effective treatment for symptomatic PVCs, high PVC burden, and PVC-induced cardiomyopathy, with high procedural success rates and favorable effects on arrhythmic burden and ventricular function. Novel approaches, including electrocardiographic imaging-guided planning, pulsed field ablation, stereotactic radioablation, neuromodulation, and renal denervation, may further expand future therapeutic options. This review summarizes the pathophysiology, clinical implications, diagnostic evaluation, and contemporary management of PVCs, with emphasis on medical therapy, catheter ablation, and emerging treatments.
