Case Report of a Leaflet Tear Due to Dehiscence of Surgical Mitral Valve Ring Treated by Combining Edge‐Edge Repair With Paravalvar Leak Occluder

This describes a percutaneous repair in the context of a patient with failed surgical mitral valve repair, where the ring dehiscence caused a hole at the base of the posterior mitral valve leaflet. Redo surgery was considered too high risk, so we combined edge‐edge repair with device occlusion of the hole in the posterior leaflet, using a Nitinol wire device designed for paravalvar leak closure. Whilst mitral valve repair is usually a successful procedure, rare complications can occur, and percutaneous solutions can offer an alternative to high‐risk surgery, where medical treatment has failed. The patient was discharged and remains well under follow‐up.
