Significance of transesophageal echocardiography in the evaluation of aortic valve stenosis

Transesophageal echocardiography (TEE) is a relatively new diagnostic method offering better resolution of cardiac anatomy than the conventional transthoracal two-dimensional echocardiography (TTE). Clinical indications for TEE have been expanding, thus the technique as a diagnostic procedure is used in numerous cardiac diseases such as endocarditis, congenital heart defect, aortic dissection, prosthetic valves dysfunction, as well as in calculation of aortic valve surface in aortic stenosis. The aim of the study was to prove TEE as a more precise method in determination of the level of seriousness of aortic valve stenosis.
