In recent years, the number of MitraClip procedures has increased among high-risk patients for open-heart surgery with mitral regurgitation. However, surgical re-intervention is sometimes required after a MitraClip procedure, and this re-intervention carries high risks considering the patients' backgrounds. We report on two cases of surgical re-intervention after MitraClip procedures. Case 1: An 82-year-old man experienced repeated heart failure due to severe mitral regurgitation (MR) caused by chronic atrial fibrillation. He underwent the MitraClip procedure because of his advanced age and frailty. However, his heart failure became uncontrollable due to an acute exacerbation of MR caused by Clip detachment. He underwent mitral valve replacement (MVR) 10 days after the MitraClip procedure. Case 2: A 72-year-old man experienced heart failure due to severe ischemic MR. The MitraClip procedure was performed because of hemorrhagic cerebral infarction and emphysema. However, two years after the MitraClip procedure, his condition was worsened due to MR and mitral stenosis. He eventually underwent MVR. If surgical re-intervention is required after a MitraClip procedure, open-heart surgery such as valve replacement is essential. When performing valve replacement surgery, it is considered important to preserve the subvalvular apparatus as much as possible to prevent complications.
