Key result
Following the Ross operation, aortic valve hemodynamics remained stable up to 5 years, while pulmonary valve hemodynamics deteriorated, 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

Serial pulmonary surveillance may be prudent post-Ross; leaves open long-term durability and reintervention strategies.
Cohort (n=132)
The Ross operation provides excellent midterm hemodynamics for the aortic valve, but significant hemodynamic deterioration occurs in the pulmonary homograft in nearly 20% of patients.
Briand et al. (2000) conducted a cohort in Aortic valve disease (n=132). Ross operation (pulmonary autograft) was evaluated on Hemodynamic performance (valve effective orifice area and mean transvalvular gradient). Following the Ross operation, aortic valve hemodynamics remained stable up to 5 years, while pulmonary valve hemodynamics deteriorated, causing suboptimal hemodynamics in 19.3% of patients.
