Abstract Background Functional mitral regurgitation (MR) in patients with heart failure can be treated medically or by transcatheter edge-to-edge repair (TEER) if medical therapy fails. Patients who are not suitable for TEER or surgical intervention might benefit from transcatheter mitral valve implantation using the TENDYNE valve. Case summary A 58-year-old male with a history of heart failure was admitted frequently with acute heart failure and functional MR, treated medically without significant improvement. He underwent mitral TEER therapy using MitraClip. A few months later, he was admitted with acute decompensated heart failure. Echocardiography showed severe MR with a detached clip from the posterior leaflet. He underwent redo mitral TEER using MitraClip as an option for treating single leaflet device detachment. He was readmitted with the same symptoms and his echocardiography showed detachment of both clips from the posterior leaflet. The patient underwent TMVI using the TENDYNE valve being not suitable for another attempt of mitral TEER. On follow-up, he was asymptomatic and echocardiography showed normal functioning mitral bioprosthesis with a mean gradient of 4 mm/Hg and no paravalvular leak. Discussion Transcatheter mitral valve implantation using TENDYNE valve is an option for treating patients with functional MR and detached MitraClips.
