Is the Quantification of Mitral Stenosis and Aortic Stenosis by Transesophageal Echocardiography Feasible?

Abstract

The quantification of gradients in patients with mitral and aortic stenosis by conventional transthoracic Doppler echocardiography is well accepted in clinical diagnostic routine. Studies comparing it with angiography showed it produced excellent results in the determination of mean and maximum transmitral gradients. In patients with aortic stenosis, measurements of transaortic mean and maximum instantaneous gradients were highly reproducible and when mean aortic gradients were compared with those obtained by other methods, results were also quite satisfactory.
