Late thrombosis of the aortic Bjork-Shiley prosthesis. Its clinical recognition and management.
Seven cases of massive thrombosis of an aortic Bjork-Shiley prosthesis were encountered among 433 valvular implants. Four patients died before treatment could be instituted, and three underwent repeat surgery successfully. Anticoagulation therapy was probably well maintained in four, and poorly maintained in three patients. These cases illustrated the need for a high index of suspicion and prom...
متن کاملCARDIOVASCULAR MEDICINE Twenty year comparison of a Bjork-Shiley mechanical heart valve with porcine bioprostheses
Objective: To compare survival and outcome in patients receiving a mechanical or bioprosthetic heart valve prosthesis. Design: Randomised prospective trial. Setting: Tertiary cardiac centre. Patients: Between 1975 and 1979, patients were randomised to receive either a Bjork-Shiley or a porcine prostheses. The mitral valve was replaced in 261 patients, the aortic in 211, and both valves in 61 pa...
متن کاملTwelve-year comparison of a Bjork-Shiley mechanical heart valve with porcine bioprostheses.
BACKGROUND Patients undergoing heart-valve replacement may receive a mechanical prosthesis, necessitating lifelong anticoagulant treatment, or a porcine bioprosthesis, which involves no absolute need for anticoagulants. METHODS We carried out a randomized, prospective trial to compare the durability of the Bjork-Shiley mechanical prosthesis (spherical tilting-disk model) and the incidence of ...
متن کاملResults of use of the pyrolytic carbon tilting disc Bjork-Shiley aortic prosthesis.
Replacement of the aortic valve with a new BjorkShiley prosthesis was performed in 1 10 patients during the period from November, 1971 to July, 1973. The previously reported Delrin-disc Bjork-Shiley valve had a built-in valvular leak of up to 10 percent due to .003” clearance. The new pyrolite-disc prosthesis is machined to a clearance of .001”. Excellent clinical results have been achieved in ...

Haemolysis with Bjork-Shiley and Starr-Edwards prosthetic heart valves: a comparative study. A comparison was made of the haemolytic complications in 85 patients with two different types of Starr-Edwards cloth-covered ball and cage prosthesis with those in 44 patients with the Bjork-Shile...
متن کاملTwo-dimensional echocardiographic features of Björk-Shiley aortic prosthetic valve dehiscence.
Dehiscence of the valve is a serious complication of prosthetic heart valve replacement. It has grave consequences unless promptly diagnosed and corrected by surgery. We report the case of a symptomless patient with near-complete detachment of the aortic prosthesis, diagnosed by radiography and two-dimensional echocardiography. This was confirmed at surgery and the dehisced prosthetic valve was...
