The rare case of a MitraClip device migrating into the left ventricular apex.

A 79-year-old man with atrial fibrillation and heart failure due to grade 4 + mitral valve regurgitation after coronary artery bypass underwent the MitraClip procedure using two clips. Three days after the procedure, chest radiographs indicated migration of one of the two clips into the left ventricle. He suffered from 3 + recurrent mitral regurgitation, tricuspid valve regurgitation. The echocardiogram and computed tomography scans indicated migration of the clip into the left ventricular apex; he underwent mitral valve replacement, removal of the migrated clip to prevent embolism, left atrial appendage closure, and tricuspid valve ring-annuloplasty. In the postoperative acute phase, embolism by detached and lost MitraClip device is possible, which can be difficult to remove.
