In this study, we sought to define the impact of intraoperative transesopha
geal echocardiography (IOTEE) among patients undergoing aortic valve replac
ement for severe aortic stenosis. We reviewed the clinical data and preoper
ative, intraoperative, and postoperative echocardiograms of all adults who
underwent aortic valve replacement for aortic stenosis and had IOTEE betwee
n January 1993 and December 1996. There were 383 patients (223 men, 160 wom
en; mean age, 69 years). Fifty-four (14%) of the 383 patients had mitral va
lve surgery at the time of aortic valve replacement. in 6 patients, mitral
valve surgery was not planned but was added because of findings on IOTEE. I
n 25 patients, mitral valve surgery was canceled on the basis of the IOTEE.
Additional information was found by IOTEE in 25 patients before and after
bypass, altering the surgical plan in IS of these 25 patients. Overall, IOT
EE altered the planned operation in 49 (13%) of the 383 patients. These dat
a support the routine use of IOTEE among patients undergoing aortic valve r
eplacement for aortic stenosis.
