Does the disc in Björk-Shiley tilting disc valves rotate postoperatively in patients?
Radiographic evidence confirms that the delrin disc in Björk-Shiley tilting disc valves rotates postoperatively, which is expected to distribute wear and prolong valve lifetime.
Björk et al. (1971) studied this question.
