Objective To investigate the early safety and efficacy of transapical transcatheter aortic valve implantation (TAVI) for high-risk elderly patients with pure aortic valve insufficiency. Methods A prospective multicenter clinical study of domestic J-valveTM TAVI for high-risk native non-calcified aortic valve insufficiency was conducted from April 2014 to May 2018, and the early postoperative results were analyzed. A total of 82 patients were enrolled, including 62 patients from West China Hospital, Sichuan University, 16 patients from Zhongshan Hospital, Fudan University, and 4 patients from Beijing Fuwai Hospital, National Center for Cardiovascular Diseases. There were 55 males and 27 females. The age was 61-90 (73.8±6.3) years. The logistic EuroSCORE was 10.0%-44.4% (17.5%±8.1%). All patients underwent TAVI using J-ValveTM system. Clinical evaluation and echocardiography were performed preoperatively and 1 month postoperatively. Multislice spiral CT was reviewed before discharge. Results Three patients were transferred to thoracotomy for cardiopulmonary bypass operation, and 1 patient had decreased cardiac function due to leakage of the valve 1 week after surgery. The overall technical and procedural success rate was 95.1% and 93.9%, respectively. During hospitalization, 1 patient died of moderate pericyclosis complicated with multiple organ failure, and 1 patient died of pulmonary infection. Six (7.6%) patients received pacemaker implantation due to new onset Ⅲ° atrioventricular block. Echocardiographic follow-up showed paravalvular leak was observed in the few of patients, mild paravalvular leak was in 13 patients on the 30th day. Two patients showed moderate paravalvular leak. Left ventricular end-diastolic volume decreased from 197.7±66.8 mL (pre-TAVI) to 147.2±53.3 mL (30-day post-TAVI) (P<0.05). Mean pressure gradient was 9.5±4.1 mm Hg (30-day post-TAVI). Conclusion This multicenter study demonstrates that TAVI with the J-Valve system for the treatment of pure aortic regurgitation is associated with sustained clinical and functional cardiovascular benefits in high-risk patients with symptomatic aortic regurgitation early-term follow-up. Our results further support that TAVI with the specific designed J-Valve system is an acceptable alternative therapy for high-risk patients with pure AR. Our result demonstrates good early-term durability and preserved hemodynamic function. The procedure appears to offer an adequate and lasting resolution for selected patients with pure aortic regurgitation.
