Abstract:
Objective To summarize the short-term results of valve-in-valve transcatheter aortic valve implantation (ViV-TAVI) in the treatment of bioprosthetic valve failure after aortic valve replacement. Methods We reviewed the clinical data of patients who underwent ViV-TAVI from 2021 to 2022 in the First Affiliated Hospital of Zhengzhou University. The valve function was evaluated by echocardiography before operation, immediately after operation and 3 months after operation. The all-cause death and main complications during hospitalization were analyzed. Results A total of 13 patients were enrolled, including 8 males and 5 females with a mean age of (65.9±8.5) years, and the interval time between aortic valve replacement and ViV-TAVI was (8.5±3.4) years. The Society of Thoracic Surgeons mortality risk score was 10.3%±3.2%. None of the 13 patients had abnormal valve function after operation. The mean transvalvular pressure gradient of aortic valve was decreased (P<0.001), the peak flow velocity of aortic valve was decreased (P<0.001), and the left ventricular ejection fraction was not changed significantly (P=0.480). There were slight perivalvular leakage in 2 patients and slight valve regurgitation in 3 patients. Three months after operation, the mean transvalvular pressure difference and peak flow velocity of aortic valve in 12 patients were significantly decreased compared with those before operation (P≤0.001). Conclusion This study demonstrates that ViV-TAVI for the treatment of bioprosthetic valve failure after aortic valve replacement is associated with favorable clinical and functional cardiovascular benefits, the short-term results are satisfactory.
