title: Temporary division of the superior vena cava for exceptional mitral valve exposure.
abstract: Temporary division of the superior vena cava allows the performance of an extensive left atriotomy from anterior to the atrial appendage laterally, then inferiorly toward the inferior vena cava. Gentle retraction then gives exceptional exposure of the entire mitral valve area. This technique has been used effectively in three patients. Anticipated potential problems with division and reanastomosis of the superior vena cava have not occurred.
