Validation of german aortic valve score in a multi-surgeon single center

Abstract OBJECTIVE: Risk assessment for operative mortality is mandatory for all cardiac operations. For some operation types such as aortic valve repair, EuroSCORE II overestimates the mortality rate and a new scoring system (German AV score) has been developed for a more accurate assessment of operati...
