Application research of three-dimensional transesophageal echocardiography in predicting prosthetic valve size for transcatheter aortic valve implantation.

ABSTRACT:

Background

Transcatheter aortic valve implantation (TAVI) is an alternative method to treat patients with severe aortic valve disease. Accurate measurement of the aortic valve annulus and selection of the appropriate artificial valve are critical to the success of TAVI. Multilayer spiral computed tomography (MSCT) is recommended as the "gold standard" for assessing the aortic valve annulus before TAVI. However, MSCT scanning may not be possible for patients with iodine allergy, renal failure, or pregnancy. The purpose of this study is to evaluate the aortic valve annulus by three-dimensional transesophageal echocardiography (3D-TEE) and compare the results with MSCT, exploring the feasibility of 3D-TEE to guide the selection of artificial valve implantation in TAVI.
