%X <B>UNASSIGNED: </B>Patients with tricuspid bioprosthetic structural valve degeneration (SVD) often present with right ventricular enlargement and severe dysfunction, which cause a higher risk for redo cardiac surgery. In 2019, our center innovated using the J-valve system for valve-in-valve (ViV) implantation to treat tricuspid bioprosthetic SVD. The purpose of this study was to summarize the clinical effect after 1-year follow-up.<BR><B>UNASSIGNED: </B>From April 2019 to October 2019, two cases of tricuspid bioprosthetic dysfunction were treated with the J-valve system. Both patients were male, aged 46 and 67 years, respectively. The preoperative evaluation showed that the risk of conventional redo open heart surgery was high. The J-valve implantation was successful in both cases. One patient had slight valve displacement when the transporter was withdrawn during the operation, and a second J-valve was implanted in an ideal position. There was no death, no delayed valve displacement, and no readmission during the follow-up period of 12 months. In both cases, there was an absence of trace tricuspid regurgitation. After 6 months of anticoagulation with warfarin, the patients were converted to long-term aspirin treatment.<BR><B>UNASSIGNED: </B>The ViV technique with J-valve is feasible and effective in treating tricuspid bioprosthetic SVD in high-risk patients, avoiding cardiopulmonary bypass and conventional thoracotomy injury.
