The German Aortic Valve Registry (GARY) includes information on a real-world, all comers basis for patients undergoing open conventional or transcatheter aortic valve interventions. There are 78 German centers enrolling data to GARY. A total of 13,860 patients are included since 2011.
- N=6253 patients underwent conventional aortic valve replacement, whereas n=2497 underwent transcatheter aortic valve implantation (n=1782 via transvascular and n=715 via transapical root). Follow-up at 1 year was known in 98% of patients.
- The 1-year mortality rate was 6.7% for isolated conventional, 11.0% for conventinal aortic valve replacement with concomitant coronary artery bypass grafting (CABG), 20.7% for transvascular and 28.0% for transapical approach.
- Stratified into risk groups by means of the EuroSCORE, the highest risk cohorts showed the same mortality at 1 year for different approaches to aortic valve intervention.
- Over 80% of patients were in the same or better state of health at 1 year after intervention.
GARY is a national registry including 55% of all aortic valve procedures performed in Germany. The number of included contemporary patients and 1-year quality of life follow-up are the main advantages of this registry. Mohr et al. showed that in the all-comer patient population, conventional surgery in operable patients yields excellent results in all risk groups. The author confirmed that transcatheter aortic valve implantation is a good alternative for high-risk patients.
We can expect now a number of important reports based on GARY. I think that GARY will help to develop new risk models to predict patient outcomes and even to design new valves. It may be also used as a platform for quality improvement in participating institutions.
