Clinical outcomes of upgrades in patients with permanent AF
Twenty-one patients were permanent AF. These improvements of cardiac function and remodeling also were observed in patients with permanent AF after upgrades (Table 2). To note, left atrium (LA) size also slightly decreased from 59.29±7.74mm at baseline to 56.44±6.46 after HPSP (P=0.010). No significant difference was found in mitral (10/6, P=0.219) or tricuspid regurgitation (10/8, P=0.727) before and after HPSP.
There was no significant difference in the improvement of the LVEF between the patients with or without AF (P=0.424). The improvements of LVEDD, QRSd also had no significant difference between the two subgroups.
