AVR type may influence thromboembolic risk via platelet effects; hypothesis-generating and should not yet change practice.
Does the type of aortic valve replacement affect platelet survival time and correlate with thromboembolism in patients with aortic valve disease?
Insertion of Starr-Edwards valves and stented aortic homografts shortens platelet survival time, which correlates with the occurrence of thromboembolism.
Steele et al. (1975) studied this question.
