    The
    first patient is a 70 year old woman with a 2 month history of 
     | 
   
   
     | 
    shortness
    of breath and dyspnea on exertion. 
    She was known 
     | 
     | 
   
   
     | 
    to
    have mitral valve (MV) prolapse and mitral regurgitation (MR). 
     | 
     | 
   
   
     | 
   
   
    | • | 
    A
    pre operative transthoracic echocardiogram (TTE) showed 
     | 
     | 
   
   
     | 
    mitral
    valve prolapse with moderately severe (3+) MR.  Cardiac 
     | 
     | 
   
   
     | 
    catheterization
    showed only minimal luminal irregularities of the 
     | 
     | 
   
   
     | 
    coronary
    arteries. 
     | 
     | 
   
   
     | 
   
   
    | • | 
    She
    had no history of esophageal disease, dysphagia, or 
     | 
     | 
   
   
     | 
    hematemesis. 
     | 
     | 
   
   
     | 
   
   
    | • | 
    She
    came to surgery for MV repair. 
    After induction of 
     | 
     | 
   
   
     | 
    anesthesia
    and endotracheal intubation a transesophageal 
     | 
     | 
   
   
     | 
    echocardiography
    (TEE) probe was inserted into the esophagus 
     | 
     | 
   
   
     | 
    and
    a comprehensive examination performed.
