Strut fractures in De Bakey aortic valves.

ABSTRACT

In two of six patients with a De Bakey aortic valve prosthesis implanted in 1973, strut fractures occurred after 7.5 and 9 years, respectively. In one case the cage and ball embolized and the outcome was fatal. The second case was recognized before embolization had occurred, and the valve could be successfully replaced. Valve replacement is recommended in cases with a De Bakey aortic prosthesis of the described type.
