Transcatheter valve-in-valve implantation treatment with the J-valve system for tricuspid bioprosthesis deterioration: a report of two cases.

ABSTRACT:

Background

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.

Case description

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 p
