Randomized Trial of TAVI vs. SAVR in Patients With Severe Aortic Valve Stenosis at Intermediate Risk of Mortality


Brief description of study

Randomized controlled, multi-center trial randomizing patients with symptomatic severe aortic stenosis at low to intermediate operative risk of mortality in a 1:1 fashion to transcatheter aortic valve implantation (TAVI) or surgical aortic valve replacement (SAVR) to test, whether TAVI is non-inferior to SAVR, as measured by all-cause mortality after 1 and 5 years.

Detailed Study Description

A paradigm-shift towards performing TAVI in intermediate- and low-risk patients has already begun, as procedural results of TAVI have improved significantly within the past years. Nevertheless, a prospective and independent comparison of surgical (SAVR) and interventional (TAVI) valve therapy in patients considered at low to intermediate risk that covers an "all-comers" patient population has not yet been performed.

The DEDICATE-trial is designed as a prospectively randomized (1:1), multi-center, comparator-controlled interventional trial to investigate whether transcatheter aortic valve implantation (TAVI) is non-inferior - as measured by all-cause mortality after 1 and 5 years

  • compared to surgical aortic valve replacement (SAVR) in the treatment of patients with symptomatic severe aortic stenosis at low to intermediate operative risk of mortality, as assessed by the Society of Thoracic Surgeons Predicted Risk of Mortality (STS-PROM)-Score.
