Region-specific gene expression profiles in the left atria of patients with valvular atrial fibrillation.


BACKGROUND Previous studies have demonstrated that atrial regions contribute differently to atrial fibrillation (AF) substrate. Pulmonary vein and the surrounding left atrial junction (LA-PV junction) are crucial areas in AF substrates and important ablation targets. OBJECTIVE To identify regional differences in the left atria of patients with AF by using… (More)
