Another Application of Transesophageal Echocardiography —Aortic Annulus Measurement
Transesophageal echocardiography has become a relatively common monitoring technique in recent years. It is valuable for the assessment of valve morphology and valve functional status. It also provides a means of evaluating wall motion abnormalities in patients with poor ventricular function, and of detecting ischemia perioperatively for better patients management. We have examined its application to the measurement of allograft aortic valves. With significant improvement in cryo-preservation of allografts, there has been renewed interest in free-hand aortic valve replacement with aortic allograft preserved in this way. Such replacement requires detailed knowledge of cardiac and aortic pathology and it demands technical excellence in sculpturing and free-hand insertion of an unstented human allograft valve.
