Comparison of 1-year clinical results of transcatheter aortic valve replacement (TAVR) using prostheses with two different frame designs in 124 patients in a single center / 中国胸心血管外科临床杂志

ABSTRACT

@#Objective    To compare and analyze the clinical effects of two kinds of frame design valves after transcatheter aortic valve replacement (TAVR). Methods    We retrospectively reviewed 124 patients who underwent TAVR and were followed up for 1 year. There were 71 males and 53 females aged 75.57±6.21 years. These patients were treated with Venus-A or Edwards Sapien aortic valves. The hemodynamics and cardiac function of these two kinds of transcatheter aortic valves (THV) were evaluated by echocardiography. The 30-day mortality and 1-year clinical effect of the patients were calculated. Results    Eight-one patients used Venus-A valve and 43 patients used Edwards Sapien valve. The aortic valve transaortic pressure gradient was reduced and the rate of perivalvular leakage was low (both 2.6%) in both groups, and there was no statistical difference between the two groups. The implantation rate of permanent pacemaker was 17.3% and 11.6%, respectively. The 1-month survival (94.0% and 93.0%) and 1-year survival (94.0% and 91.0%) rates were not statistically different. Conclusion    The two groups of THV with different stent structures have good short-term clinical effect and low implantation rate of permanent pacemaker.
