Objective To evaluate the efficiency and safety of intraprocedural valve-in-valve deployment for treatment of aortic regurgitation following transcatheter aortic valve replacement (TAVR).Methods Consecutive patients (n=333) who diagnosed with severe aortic stenosis and underwent TAVR in Zhongshan Hospital affiliated to Fudan University from October 3rd, 2010 to April 21st, 2021 were included. There were 208 males and 125 females aged 76.0±7.0 years. There were 316 patients underwent simple TAVR (simple TAVR group) and 17 patients underwent intraprocedural valve-in-valve deployment following TAVR (valve-in-valve group). Their clinical and echocardiographic outcomes were evaluated and compared.Results There was no significant difference between the two groups of patients at postoperative 30 d and 1 year in all-cause mortality (4.4% vs. 0, P=1.000; 6.3% vs. 0, P=1.000), incidence of pacemaker implantation (10.4% vs. 17.6%, P=1.000; 11.8% vs. 17.6%, P=1.000), incidence of ischemic stroke (1.3% vs. 0, P=1.000; 1.3% vs. 0, P=1.000), mean trans-aortic pressure gradient (11.4±6.4 mm Hg vs. 8.9±4.9 mm Hg, P=0.099; 10.5±7.6 mm Hg vs. 11.2±5.2 mm Hg, P=0.432), left ventricular ejection fraction (62.0%±9.0% vs. 57.0%±12.0%, P=0.189; 63.0%±7.0% vs. 60.0%±8.0%, P=0.170), and incidence of mitral valve dysfunction (0.6% vs. 5.9%, P=1.000; 0.6% vs. 5.9%, P=1.000).Conclusion It is feasible to treat perivalvular leakage with valve-in-valve technology in the procedure of TAVR, and the short and medium-term effects are satisfied.
