WebComplications include embolic events, bleeding, valve obstruction (due to thrombosis or pannus), infective endocarditis, structural deterioration (particularly for bioprosthetic valves), paravalvular regurgitation, hemolytic anemia, and prosthesis-patient mismatch. (See "Diagnosis of mechanical prosthetic valve thrombosis or obstruction" .) WebIn this condition, hemolysis is due to mechanical trauma caused by prosthetic cardiac valves. High blood flow around the prosthetic causes red blood cells to fragment leading to intravascular hemolysis. Any damaged cells that do not hemolyze in circulation are removed by the spleen via extravascular hemolysis. 1,2
