Background: To investigate the effect of successful RFCA in patients with idiopathic outflow tract PVCs (OT-PVC) on left heart functions, neurohormonal activation, functional status, and heart failure-related quality of life (HFQoL), with an integrated approach.
Methods: Patients with frequent OT-PVCs, determined by 12-lead surface ECG who underwent radiofrequency catheter ablation (RFCA) with an acute success, were prospectivelly enrolled. Left heart functions were evaluated with the use of transthoracic echocardiography, neurohormonal activation with N-terminal Pro-brain natriuretic peptide (BNP), functional class with New York Heart Association (NYHA) and 6-min walking distance (6MWD), and HFQoL with Minnesota Living with Heart Failure Questionnaire (MLHFQ), at baseline and at 6 months.
