Three-dimensional transoesophageal echocardiography in a patient undergoing percutaneous mitral valve repair using the edge-to-edge clip technique

We report a case of percutaneous mitral valve repair, using the Mitraclip device, in which we show that application of real-time three-dimensional transoesophageal echocardiography (3D-TEE) is extremely helpful for the guidance of this procedure. Because of its excellent visualization capacities, 3D-TEE simplifies the transseptal puncture, the positioning of the clip above the mitral valve orifice, the grasping of the mitral valve leaflets, and the evaluation of the final result. Therefore, we conclude that 3D-TEE has the potential to increase the safety and efficacy of this new technique to treat mitral regurgitation in patients who cannot undergo conventional valve surgery.
