Atrial ectopy after pulmonary vein isolation and left heart reverse remodeling in patients with atrial fibrillation

Abstract: Background Maintenance of sinus rhythm after pulmonary vein isolation (PVI) for atrial fibrillation (AF) is associated with left atrial (LA) and ventricular (LV) reverse remodeling, although the degree varies among individuals. We hypothesized that frequent premature atrial complex (PAC) after PVI may attenuate the left heart reverse remodeling benefited from maintenance of sinus rhythm. Methods We included 82 AF patients who underwent first‐time PVI and 24‐h Holter recordings at 6 months after PVI. All patien… Show more

“…PAC occurrence is associated with LA dilation and risk factors for atrial cardiomyopathy in an ESUS population ( Pinho et al, 2015 ; Vinther et al, 2017 ; Cha et al, 2020 ), suggesting that PACs are a clinical marker of atrial cardiomyopathy ( Sajeev et al, 2019 ). Furthermore, the presence of PACs after AF ablation results in a significant decrease in left atrial reverse remodeling ( Hasegawa et al, 2019 ), highlighting a direct role of PACs in atrial cardiomyopathy.…”
