From April 2018 to February 2021, 150 patients underwent MitraClip implantation for severe functional mitral regurgitation (MR) at our hospital. Two of our patients, an 85-year-old man and an 84-year-old woman, developed a single leaflet device attachment in the acute phase after the implantation and had severe residual MR requiring surgical correction. The recurrent MR was first pointed out on day 5 and day 4, and the duration between MitraClip implantation and surgery was 13 and 55 days, respectively. Due to strong adhesions with the clips and severe valve damage after MitraClip implantation, both cases underwent mitral valve replacement with a good postoperative course. In patients with a high-risk baseline profile, surgical mitral valve replacement after failed MitraClip implantation should be considered at an optimal timing, and a detailed echocardiographic follow-up is required.
