Key result
After the Ross operation, aortic valve hemodynamics remained stable up to 5 years, but the pulmonary valve showed significant deterioration, causing suboptimal hemodynamics in 19.3% of patients.
Population
132 consecutive patients with aortic valve disease, mean age 40±11 years, 62% male.
Design
Cohort
Follow-up
up to 5 years

May warrant pulmonary homograft surveillance after Ross; leaves open durability beyond 5 years and alternatives.
Cohort (n=132)
While the pulmonary autograft maintains excellent hemodynamics in the aortic position up to 5 years after the Ross operation, the pulmonary homograft frequently develops moderately high gradients and deterioration.
Briand et al. (2000) conducted a cohort in Aortic valve disease (n=132). Ross operation (pulmonary autograft) was evaluated on Valve effective orifice area (EOA) and mean transvalvular gradient. After the Ross operation, aortic valve hemodynamics remained stable up to 5 years, but the pulmonary valve showed significant deterioration, causing suboptimal hemodynamics in 19.3% of patients.
