Abstract:
Objective:To summarize the experience and early outcomes of transapical mitral valve-in-valve procedure with J-Valve in patients with bioprostheses degeneration.Methods:The clinical data of 29 patients who underwent mitral transcatheter valve-in-valve implantation with J-Valve from April 2020 to March 2021 were retrospectively analyzed. There were male 16 and female 13 patients with average age (72.0±11.6) years. Patients underwent previous mitral valve replacement with bioprostheses of Hancock Ⅱ in 17, Edwards SAV in 7, Edwards Perimount in 3, Balmedic in 1, Mosaic in 1. The size of mitral bioprostheses included 25 # for 8 patients, 27 # for 17 patients, and 29 # for other 4 patients. The operations were performed in the hybrid operation room. Under X-ray fluoroscopy and TEE monitoring, the retro-preseted J-valve was implanted into the mitral bioprosthetic valve via the intercostal space and apical puncture. Results:One patient was converted urgently to mediate sternotomy, and the transcatheter mitral valve was reset after opening left atrium on cardiopulmonary bypass due to the migration of transcatheter valve. twenty eight patients were successfully completed transcatheter mitral valve-in-valve procedure with technical success achieving in 96.6% . Among the 28 patients who successfully were completed valve-in-valve procedure, 1 died and 27 were discharged in well condition. The mean mitral transvalvular gradient was (7.6±2.2)mmHg(1 mmHg=0.133 kPa), no death or other major complications occurred during the follow-up.Conclusion:The application of J-Valve interventional valve in patients with bioprosthesis degeneration can achieve favourable early outcomes, even if the patient was replaced with a small bioprosthesis in the previous operation, the hemodynamic effect was still satisfactory.
