Transesophageal Echocardiographic Evaluation of a Double Orifice Mitral Valve

Abstract

Intraoperative transesophageal echocardiography currently is used routinely for many cardiothoracic surgical procedures. Although it is often used for intraoperative cardiac monitoring and to confirm preoperative echocardiographic findings, it may sometimes result in the discovery of unexpected pathology. In this e-challenge, a patient was found to have a mitral valve abnormality that was not previously detected on the preoperative transthoracic echocardiogram. The mitral valve anomaly subsequently was evaluated to characterize the anatomy, interrogate the valve, and provide a diagnosis.
