RV function declines similarly after autograft or homograft AVR; confirms equivalent RV impact and supports Ross procedure safety.
Does pulmonary autograft replacement of the aortic valve affect right ventricular function differently than aortic homograft replacement in patients undergoing aortic valve surgery?
Aortic valve replacement with either a pulmonary autograft or an aortic homograft leads to similar degrees of persistent right ventricular longitudinal dysfunction, indicating the Ross procedure does not cause more pronounced RV impairment.
Carr‐White et al. (1999) studied this question.
