Key result
A patient with rheumatic mitral stenosis experienced rare complications including a papillary tumour of the mitral valve and thrombotic occlusion of a xenograft prosthesis.
Case Report (n=1)
Highlights a rare case of thrombotic occlusion of a xenograft prosthesis and a papillary tumor of the mitral valve, suggesting cross-sectional echocardiography for diagnosis.
May warrant consideration in complex mitral stenosis differentials; case report leaves diagnostic strategies open for validation.
A patient with rheumatic mitral stenosis and previous cerebral embolism had a myocardial infarction during cardiac catheterisation. She later developed severe mitral regurgitation one year after open valvotomy and at valve replacement was found to have a papillary tumour of the mitral valve. Unexplained low cardiac output occurred four days after operation. Postmortem examination showed thrombotic occlusion of the xenograft prosthesis, a complication not previously seen with tissue valves. Both of these rare events were suggested by the patient's clinical course and could have been diagnosed with cross sectional echocardiography.

James et al. (1985) conducted a case report in Rheumatic mitral stenosis and complicated mitral valve disease (n=1). Open valvotomy and valve replacement with a xenograft prosthesis was evaluated on Clinical complications (myocardial infarction, severe mitral regurgitation, papillary tumour, thrombotic occlusion). A patient with rheumatic mitral stenosis experienced rare complications including a papillary tumour of the mitral valve and thrombotic occlusion of a xenograft prosthesis.
