Artifact Mimicking Mechanical Valve Dysfunction on Intraoperative Transesophageal Echocardiography Following Redo Mitral Valve Replacement
Intraoperative transesophageal echocardiography (TEE) is vital for assessing prosthetic valve function, but imaging artifacts can lead to misdiagnosis. We describe a case of a 54-year-old man who underwent redo mitral valve replacement with a mechanical prosthesis, in which intraoperative TEE suggested prosthetic leaflet immobility. This prompted surgical re-exploration, which revealed normal valve function.
