Severe, transient aortic insufficiency after bovine pericardial aortic valve replacement: a cautionary note.

Author information

Department of Cardiac Surgery, North Shore Medical Center, Salem, Massachusetts 01970, USA.


Three patients demonstrated severe, central aortic insufficiency noted immediately upon removal of the aortic cross clamp after aortic valve replacement with a bovine pericardial Edwards Magna valve. After maintaining left ventricular decompression, the aortic insufficiency resolved in less than 1 hour. Knowledge of this phenomenon will prevent unnecessary prosthetic valve explantation and re-replacement.
