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

Expulsion of the disk of a Bjork-Shiley aortic prosthesis after temporary removal.

A 42-year-old woman was diagnosed by cardiac catheterization as having severe mitral stenosis and grade-3/4 aortic regurgitation. The patient underwent mitral commissurotomy and replacement of the aortic valve with a No. 21 Bj#{246}rkShiley tilting-disk prosthesis. The prosthesis was fixed in place with 16 single sutures (Ethiflex). In the immediate postoperative period the clinical picture and...

Results 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 ...
