RV systolic excursion declines equally after autograft or homograft AVR; confirms no unique RV impairment with the Ross procedure.
Does pulmonary autograft replacement of the aortic valve compared to aortic homograft replacement worsen right ventricular function in patients undergoing aortic valve replacement?
Aortic valve replacement with either a pulmonary autograft or an aortic homograft leads to a similar degree of persistent right ventricular longitudinal dysfunction, indicating the Ross procedure does not uniquely impair RV function.
