Transcatheter Aortic Valve Implantation in Western NORway
Transcatheter Aortic Valve Implantation in Western NORway
A prospective study of 600 patients with severe aortic stenosis (AS) and symptoms who
 underwent TAVI at the Haukeland university hospital, Bergen, Norway.
A prospective study of 600 patients with severe aortic stenosis (AS) and symptoms who
 underwent TAVI at the Haukeland university hospital, Bergen, Norway between January 2012 and
 July 2019.

 Demographics, clinical data including cardiovascular risk factors, arterial and
 echocardiographic parameters were prospectively collected. The data on all-cause mortality
 will be collected. Echocardiograms (immediate before TAVI, at discharge after TAVI and at
 6-12 months follow-up) will be analyzed. The main scientific objectives are:

 To assess survival benefits of TAVI according to baseline risk profile. To determine the
 echocardiographic predictors of left ventricular mass regression and left ventricular
 function recovery.

 To evaluate global LV load (Zva=valvular-arterial impedance) following TAVI. To assess the
 impact of various types of blood pressure responses immediately after TAVI on clinical
 outcomes.
Inclusion Criteria:

 1. Hemodynamically severe aortic stenosis and symptoms

 2. A decision of TAVI by Heart team

 3. Patients undergoing TAVI (transcatheter aortic valve implantation)

 4. Life expectancy > 1-2 years

 Exclusion Criteria:

 1. Sever frailty

 2. Severly reduced cognitive function

 3. Multiple comorbid conditions

 4. Technically not suited for TAVI
