CTICasesTendyne Transcatheter Mitral Valve Replacement
Imaging findings
Chest radiographs show a prosthetic mitral valve device consisting of a self-expanding double-frame nitinol stent positioned across the mitral annulus. A distinguishing radiopaque feature is the anchoring pad positioned at the left ventricular apex, connected to an internal tether.
Key takeaways
The Tendyne system is a specialized transcatheter mitral valve replacement (TMVR) device deployed via a transapical approach. Recognizing its characteristic radiographic markers—specifically the apical anchoring pad and the double-frame stent—is essential to prevent misinterpreting the hardware as a foreign body or displaced catheter.
