Fig. 1 Gross view of the explanted mitral prosthesis shows an excessive clearance between the occluder and the inner prosthetic ring, most likely caused by concentric wear of the Delrin disc. A, Atrial view; B, ventricular view. The Journal of Thoracic and Cardiovascular Surgery 1994 107, 318-319DOI: (10.5555/uri:pii:S0022522394704961) Copyright © 1994 Mosby, Inc. Terms and Conditions
