Assessment of cyclic changes in the diameter of the aortic annulus using speckle-tracking trans-esophageal echocardiography.

Abstract

It is uncertain whether dynamic variation in the diameter of the aortic annulus occurs during the cardiac cycle in humans. The purpose of this study was to analyze cyclic changes of the aortic annulus using speckle-tracking trans-esophageal echocardiography. The subjects were 40 patients with aortic stenosis and 40 controls. Absolute and relative changes in… (More)
