Mitral Valve Mass Detected on Preoperative Transesophageal EchocardiogramA 45-YEAR-OLD WOMAN with past medical history significant for hypertension, asthma, and anemia was admitted to the authors' institution with complaint of dyspnea on exertion.

The patient was scheduled for an aortic valve replacement and possible aortic root replacement.
