Outcomes of stented bovine pericardial aortic valvular prostheses were evaluated over a 30 year experience. 48% had concomitant CABG and 26% had additional valve procedures at the time of implant. Explants were required in 1.9% at 10 years and in 15% by 20 years. Explant rates were 3-fold higher in patients younger than 60 years. Patient-prosthesis mismatch and high gradients were associated with a higher risk of explant.
