[Microcomputer-assisted system for photographing the movements of biological valve prostheses].
The aim of the study was to develop a clinically usable system of photographic imaging of the movements of biological valve transplants and of evaluating temporal and spatial relationships. The system has been established by means of a microcomputer and associated peripheral electronic equipment so that there is no need to use a high-speed camera. Functioning of the system was verified by testing 37 aortal valve allotransplants and the Björk Shiley mechanical valve prosthesis.
