Although it is considered a benign pathology, it can also be associated with embolic events. We report 42-year-old woman who admitted to our clinic with the palpitation and dyspnea on exertion. Apical diastolic murmur was present in physical examination. On echocardiography mitral valve posterior leaflet had a typical 'domed' appearance in diastole while anterior leaflet was restricted in motion with a fibrocystic formation on the ventricular side, causing mild to moderate mitral stenosis. We decided medical follow-up with the patient choice and we have been following for two years without any complications.[No abstract available]en10.19127/mbsjohs.705462https://doi.org/10.19127/mbsjohs.705462info:eu-repo/semantics/openAccessmitralblood cystrheumatic valveCase Report62275273
