Patient – prosthesis mismatch Patient – prosthesis mismatch is often noted in aortic position, that too after surgery for aortic stenosis. In aortic stenosis the aortic root is

Bioprosthetic valve degeneration Bioprosthetic valve degeneration causes prosthetic valve failure like prosthetic valve thrombosis and pannus formation. Host related factors which predispose to bioprosthetic valve degeneration are: Younger

Etiological types of prosthetic valve dysfunction Different etiological types of prosthetic valve dysfunction are: Prosthetic valve thrombosis Pannus formation – growth of fibrotic tissue from the annulus region
