Abstract:
Objective To evaluate the safety and early-stage efficacy of transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS) using a new generation balloon-expandable (BE) valve by collecting the baseline and follow-up data. Methods We retrospectively reviewed the clinical data of severe AS patients who received TAVR with BE valve (Sapien 3) in Fuwai Hospital from September 2020 to June 2022. We collected the echocardiographic data as well as follow-up results at post-procedure, 1, 3, 6 and 12 months. According to the Sievers classification criteria, the patients were divided into a normal group and a bicuspid aortic valve group. Results Finally 62 patients were collected, including 31 females and 31 males with an average age of 71.44±9.17 years. There was 61 patients implanted successfully with BE valve and only 1 was transferred to surgical replacement. There was no mortality or severe complications. Echocardiographic assessment showed significant reduction of the pressure gradient (P＜0.001) and the effect was consistent to postoperative 12 months. After the treatment of patients with different aortic valve morphology using balloon dilation, the condition of valve stenosis improved. Conclusion The use of BE valves has good safety and early efficacy in patients with severe AS of different valve morphology.
