Outlet strut fracture of Björk-Shiley convexo concave heart valves: the UK cohort study.
OBJECTIVE To investigate the risk of outlet strut fracture (OSF) in Björk-Shiley convexo concave (BSCC) valves in relation to patients' clinical and valve characteristics. DESIGN A cohort of 2977 patients with 3325 valves with a follow up of 18 years. SETTING 38 cardiac implantation centres in the UK.

متن کاملStrut fracture of Björk-Shiley convexo-concave valve in Japan--risk of small valve size--.
BACKGROUND The Björk-Shiley convexo-concave (BSCC) prosthetic valve was introduced in 1979. Between 1979 and 1986, approximately 86,000 BSCC valves were implanted. By December 31, 1994, 564 complete strut fractures had been reported to the manufacture.

متن کاملBjork-Shiley Convexo-concave Heart Valves A Clinical and Economic Evaluation
Background. Bjork-Shiley convexo-concave heart valves have an increased risk of mechanical failure. One might consider prophylactic rereplacement as a preventive measure to avert the disastrous consequences of these failures. We investigated the effect that prophylactic rereplacement has on survival of individual patients and on the medical costs. Methods and Results. Quantitative estimates for...

DESIGN Cross sectional study. PATIENTS 137 patients who received either a BScc valve or a Sorin Biomedical spherical valve during a randomised trial between 1982 and 1983 at St Antonius Hospital, Nieuw...
