ABSTRACT
Objective To evaluate the effectiveness of transcatheter aortic valve replacement (TAVR) using domestic valves for treating aortic valve stenosis or regurgitation, and to explore the incidence of cardiac conduction block after surgery and its influence on the prognosis of the patients. Methods The patients with severe aortic valve stenosis or regurgitation receiving TAVR surgery in our department from Sep. 2017 to Jan. 2018 were enrolled in this study. The TAVR surgery was performed with domestic valves (J-Valve or Venus-A), and the outcomes and incidence of complications were assessed after surgery. The patients were observed for the incidence of new-onset cardiac conduction block during and after TAVR and the recovery of arrhythmia during hospitalization. According to the presence of cardiac conduction block at discharge, the patients were divided into normal rhythm group and conduction block group. The baseline and postoperative characteristics, and left ventricular structure and function were compared between the two groups. Results Sixteen patients were enrolled in this study, including 12 in the normal rhythm group and 4 in the conduction block group. Brain natriuretic peptide ([1 114.87±802.32] pg/mL vs [530.39±276.26] pg/mL, P=0.026), aortic transvalvular pressure difference ([83.06±37.76] mmHg vs [24.14±9.73] mmHg, P0.05). Conclusion TAVR with domestic valves can effectively reduce the aortic transvalvular pressure difference with fewer complications. It may cause complete left bundle branch block, which has no significant influence on the short-term adverse cardiac events and cardiac function after operation.
