				        	We report a 69-year-old woman with transient mitral valve regurgitation and hemolysis following mitral valve replacement with a Carpentier-Edwards pericardial bioprosthesis. She had a history of congestive heart failure caused by mitral valve regurgitation so we performed mitral valve replacement with a Carpentier-Edwards pericardial bioprosthesis (Model 6900). Three days after surgery, a systolic murmur became clearly audible and the serum LDH level reached a maximum of 2, 018IU/l on postoperative day 10. Echocardiography showed regurgitant flow through the center of the bioprosthetic valve. It was thought that stent distortion of the implanted pericardial bioprosthesis had occurred and re-operation would be necessary, but the regurgitant flow disappeared suddenly on postoperative day 12. If mitral valve regurgitation occurs following mitral valve replacement with a pericardial bioprosthesis, stent distortion should be taken into consideration.
