Disc and strut embolisation after minor strut fracture in a Bjork-Shiley mitral valve prosthesis.

Disc embolisation after minor strut fracture in a Björk-Shiley mitral valve prosthesis.

We report the successful management of a patient who suffered embolisation of a Bjork-Shiley mitral prosthetic valve disc after fracture of the minor strut. Emergency surgical treatment was responsible for her survival. The disc was recovered through the abdominal aorta at a subsequent operation, performed once the condition of the patient had stabilised. This experience confirms previous repor...

Strut 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. We experienced a case of an outlet strut fracture and investigated the risk of BSCC prosthetic valve fractures in Japan. METHODS AND RESULTS T...

Haemolysis after mitral valve replacement with the Björk-Shiley and the Lillehei-Kaster disc valve prosthesis.

The present study reports on the incidence and degree of intravascular haemolysis in 33 patients with Björk-Shiley tilting disc prosthesis and in 34 patients with Lillehei-Kaster pivoting disc valve prosthesis in the mitral position examined 12 to 24 months after the operation. Serum haptoglobin, serum lactate dehydrogenase, serum bilirubin, and haemoglobin estimations were performed. Significa...

Experience with retrograde left heart catheterization through the Bjork-Shiley aortic valve prosthesis: a preliminary report.

Near fatal puerperal thrombosis on Björk-Shiley mitral valve prosthesis.

A 22-year-old woman required emergency mitral valve replacement three weeks post partum because of thrombotic obstruction of her prosthetic mitral valve. Low dose subcutaneous heparin was administered from the 17th week of pregnancy. Though there was a successful fetal outcome, heparin did not prevent thrombosis on the prosthesis and its continuation into the puerperium proved nearly fatal.
