German Aortic Valve Score: a new scoring system for prediction of mortality related to aortic valve procedures in adults

Abstract

It is well known that a predictive model works best in the setting where it was developed; therefore, the German AV Score fits well to the patient population in Germany. It was designed for fair and reliable outcome evaluation. It allows comparison of predicted and observed mortality for conventional aortic valve surgery and transcatheter aortic valve implantation in low-, moderate- and high-risk groups. Thus, it enables primarily a risk-adjusted benchmark of outcome and fosters the efforts for continuous improvement of quality in aortic valve procedures.
