Subgroup analysis of the proportion of patients undergoing AVR that included concomitant TAS for each time epoch. A, Patients aged less than 50 years or 50 or more years. A greater proportion of younger patients underwent aortic surgery, at an increasing frequency of the study duration. B, Gender. Men more frequently underwent aortic surgery, at an increasing frequency of the study duration. C, Type of hospital. Concomitant aortic surgery was performed more frequently at teaching hospitals, at an increasing frequency of the study duration. Nonteaching hospitals did not show a similar trend to perform concomitant aortic surgery over the study duration. There seemed to be a more consistent and prominent trend to a greater proportion of aortic surgeries in teaching hospitals.
