Interventions

Group 1: Intraindividual comparison of 3D transesophageal echocardiography measurements and MSCT (multidetector computed tomography) measurements for the selection of the appropriate valve prosthesis

Eligibility

Age

18 Years to No maximum

Inclusion criteria

Inclusion criteria: Severe aortic stenosis and positive heartteam vote for TAVR

Exclusion criteria: <18 years; operational coronary heart disease; acute myocardial infarction; TIA, PRIND, Apoplex in the last 6 months, no patient consent

Design outcomes

Primary

Measure	Time frame
Non-inferiority of the annulus diameter measurement in the 3D TEE ultrasound vs MSCT (Multidetector computed tomography). The measurement of the diameter using 3D TEE and CT is performed before intervention.	—

Secondary

Measure	Time frame
Exploratory data analysis of the following parameters: - Height of the coronary arteries, sinus of valsalva diameter, sinutubular junction diameter, (the measurement of these parameters using CT and TEE are performed before intervention). - angulation angle (the angle is measured by using CT before intervention and by fusion periinterventionally).	—
