An unexpected complication of the MitraClip device: one of the arms gets stuck inside the guide catheter in the left atrium.

Percutaneous edge-to-edge mitral valve repair using the MitraClip (Abbot Vascular, USA) system is a promising technique for mitral regurgitation treatment in select high-risk surgical patients. Although the safety and efficacy of the technique have been demonstrated, a few complications of the MitraClip device have been reported. In this report, we present a rare complication that recently occurred during the performance of a MitraClip procedure in a patient with severe functional mitral regurgitation. One MitraClip arm got stuck inside the guide catheter in the left atrium and a decision was made to discontinue percutaneous intervention because the problem could not be resolved.
