Abstract:
Objective To summarize the early results and clinical experience of using the J-Valve for transcatheter valve-in-valve implantation in patients with degenerated bioprosthesis at different anatomic positions. Methods A retrospective analysis was conducted to evaluate the short-term outcomes of 39 consecutive patients who underwent transcatheter valve-in-valve implantation using the J-Valve System in the Department of Cardiac Surgery of Guangdong Provincial People’s Hospital from April 2020 to August 2021 due to bioprosthetic degeneration at different anatomic positions. Among them, 35 patients underwent transcatheter mitral valve-in-valve (TMViV) implantation, 1 transcatheter aortic valve-in-valve (TAViV) implantation, 1 transcatheter tricuspid valve-in-valve (TTViV) implantation, 1 TMViV implantation with simultaneous TAViV implantation, and another one TMViV implantation with simultaneous transcatheter aortic valve replacement (TAVR) and perivalvular leakage (PVL) closure. Results Among the 35 patients who underwent isolated TMViV implantation, 17 were male and 18 were female with a mean age of 72.6±10.8 years. Mean duration between two operations was 10.5±2.7 years. The mean Society of Thoracic Surgeons and EuroSCORE Ⅱ scores were 12.95%±9.61% and 13.91%±8.94%, respectively. The device success rate was 97.1% and no death occured during the operation. One patient was transferred to thoracotomy due to device displacement, 1 was re-opened for uncontrolled bleeding, and 1 presented left ventricular outflow tract obstruction. One patient underwent craniotomy due to intracranial hemorrhage within 30 days after surgery, and no other complications occurred including death, stroke, permanent pacemaker implantation, cardiac tamponade, or re-hospitalization. The mean follow-up time was 6.0±4.4 months, the mean mitral valve gradient was significantly improved (10.4±2.0 mm Hg vs. 5.5±1.2 mm Hg, P<0.05), and the New York Heart Association class≤Ⅱ in all the patients at the last follow-up. Among the other 4 patients who did not undergo isolated TMViV implantation, the transapical TAViV implantation and the trans-right atrium TTViV implantation were successful without intra- or post-operative complications. The patient who underwent TMViV and TAViV implantation simultaneously via transapical approach died of severe pulmonary hemorrhage and multiple organ failure 16 days after surgery. The other patient who underwent transapical TMViV combined with TAVR and PVL closure died of septic shock 10 days after the surgery. Conclusion Transcatheter valve-in-valve implantation using the J-Valve system is shown to be a safe and effective procedure to treat mitral, aortic and tricuspid bioprosthetic valve dysfunction in high-risk patients, providing a new alternative to surgical surgery for degenerated bioprosthesis at different anatomic positions. However, simultaneous different valves intervention should be very cautious.
