    | • | 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.
