Ds. Kucukaksu et al., Thirty years survival without anticoagulation after aortic valve replacement with a Bjork-Shiley prosthesis, J HEART V D, 10(4), 2001, pp. 548-549
Anticoagulation is mandatory in all mechanical valve replacements and, when
well-managed, permits both embolism and valve thrombosis to be kept at low
levels. Here, we report the case of a male patient who has survived 30 yea
rs without anticoagulation following aortic valve replacement with the Bjor
k-Shiley prosthesis.
