Why the study?
Does the Starr-Edwards silastic ball valve improve long-term survival and reduce complications compared to the St Jude Medical bi-leaflet valve in patients undergoing implantation for aortic stenosis?
Population
261 patients who were alive 30 days after implantation for aortic stenosis
Comparison
Starr-Edwards silastic ball (SESB) valve vs St Jude Medical bi-leaflet (SJMB) valve
Design
Cohort
Follow-up
Mean 3.0 years (0.1-7.9 years)

Comparable outcomes with SESB and SJMB valves should not yet alter selection; leaves open need for randomized comparisons.
Does the Starr-Edwards silastic ball valve improve long-term survival and reduce complications compared to the St Jude Medical bi-leaflet valve in patients undergoing implantation for aortic stenosis?
Starr-Edwards silastic ball and St Jude Medical bi-leaflet prostheses demonstrated comparable and acceptable long-term performance and survival in patients with aortic stenosis.
Lund et al. (1990) studied this question.
