standard valve, and have mitigated patient-prosthesis mismatch in cases of
narrow aortic root.
Nicoloff et al. reported an early series of 232 bileafl et valve implants over
a three year period without any device failures. 49 A larger series was reported
by DeBakey's group, which retrospectively reviewed 815 implants. They
reported a freedom from valve-related death or reoperation at three years
at 96.4% for aortic and 98.3% for mitral implants. 50
