Abstract
Numerous mechanical prostheses are currently utilized for heart valve replacement. Fluoroscopy is a useful technique to identify prosthetic valves, to evaluate their function and to follow-up the patients' condition. Scattered and contrasting data, however, have been reported about the radiographic appearance of Björk-Shiley heart valves. This study shows that each Björk-Shiley valve model has characteristic radiographic features that can be readily determined by fluoroscopic evaluation, leading to easy and accurate non-invasive identification.
Key Words: Björk-Shiley valve Sotin valve fluroscopy
