Abstract:
Objective To discuss the operation skill and clinical effects of using domestic balloon-expandable Prizvalve® transcatheter "valve-in-valve" to treat the degenerated bioprosthesis in the tricuspid position. Methods All the admitted surgical tricuspid valve bioprosthetic valve replacement patients were evaluated by computerized tomography angiography (CTA), ultrasound, and 3D printing technology, and 2 patients with a degenerated bioprosthesis were selected for tricuspid valve "valve-in-valve" operation. Under general anesthesia, the retro-preset Prizvalve® system was implanted into degenerated tricuspid bioprosthesis via the femoral vein approach under the guidance of transesophageal echocardiographic and fluoroscopic guidance. Results Transcatheter tricuspid valve implantation was successfully performed in both high-risk patients, and tricuspid regurgitation disappeared immediately. The operation time was 1.25 h and 2.43 h, respectively. There was no serious complication in both patients, and they were discharged from the hospital 7 days after the operation. Conclusion The clinical effect of the degenerated tricuspid bioprosthetic valve implantation with domestic balloon-expandable valve via femoral vein approach "valve-in-valve" is good. Multimodality imaging and 3D printing technology can safely and effectively guide the implementation of this innovative technique.
