A 44-year-old woman with over 20 years history of rheumatic heart disease developed progressive heart failure from aortic stenosis and mitral restenosis after open mitral commissurotomy. In December, 1986, she underwent aortic and mitral valve replacements with Medtronic Hall prosthesis (aortic: 21mm, mitral: 27mm). Following an eventful recovery, she was discharged from the hospital and continued on a regimen of Coumadin. In February, 1991, the patient developed chest and back pain, which necessitated her emergency admission to our clinic. During the coronary examination, the aortic prosthetic occluder was not moving, fixed in the opening position, lasting from one to several minutes. She underwent emergency operation for replacement of the defective valve. At operation, we noted the pannus formation into the valve orifice on the inflow side of aortic prosthesis. She made a satisfactory recovery and has enjoyed good health since that time.
