Mitral valve repair is the preferred treatment option in primary mitral valve disease especially degenerative mitral valve disease. Surgical results are quite successful with appropriate surgical techniques in suitable patients. But technically, surgery may result in any degree of narrowing of the orifice of the mitral valve. Also, surgical repair of rheumatic mitral valve disease is technically more demanding however, mitral repair is preferred over mechanical valve implantation if possible. İn this case report we presented the case of functional mitral stenosis after surgical mitral valve repair and annuloplasty ring implantation for rheumatic mitral regurgitation. Written and verbal consents of the patient were obtained prior to this case report.
