Usefulness of three-dimensional transesophageal echocardiography in retrieval of a dislodged vascular plug used to close paraprosthetic mitral regurgitation.

In this report, we describe a case of periprocedural dislodgement of an Amplatzer Vascular Plug II device during percutaneous closure of severe paraprosthetic mitral regurgitation. The free plug in the left atrium was successfully retrieved percutaneously using a snare inserted through a sheath under live/real time three-dimensional transesophageal echocardiographic guidance. This proved crucial not only in guiding device deployment but also in detecting and helping management of complications.
