Why the study?
Percutaneous transcatheter edge-to-edge mitral valve repair may be unsuccessful, resulting in significant residual or recurrent MR.
Demonstrates the feasibility of minimally invasive mitral valve replacement as a treatment option for patients with residual or recurrent MR after failed transcatheter edge-to-edge repair.
Answers are grounded in this paper and cite their sources.
May support minimally invasive mitral valve replacement after failed TEER in select patients; hypothesis-generating and requires larger studies before broader adoption.
Percutaneous transcatheter edge-to-edge mitral valve repair is available for treatment of both functional and degenerative mitral regurgitation (MR). This technique may be unsuccessful resulting in significant residual or recurrent MR. We described a successful minimally invasive mitral valve replacement in a patient with severe functional MR due to left ventricular dysfunction who previously underwent a transcatheter edge-to-edge repair.
