KROK 1 Stomatology 2015 – Question 177 · KROK (Dentistry)
Postmortem examination of a patient with a long history of rheumatism revealed thickening and shortening of the mitral valve leaflets with abundant thrombotic deposits. Histological examination of the valve leaflets confirmed sclerosis and revealed multiple foci of connective tissue disorganization in form of mucoid and fibrinoid swelling, as well as deendothelization foci. Endothelium defects were covered with thrombotic deposits of 1-2 mm. What type of valvular endocarditis is the case?
- A. Acute verrucous endocarditis
- B. Diffuse valvulitis
- C. Fibroplastic endocarditis
- D. Recurrent verrucous endocarditis
- E. Polypous-ulcerative endocarditis
Hint
Note that the valve shows both old sclerotic changes and fresh disorganization with small thrombi - think about what that combination means in a long rheumatic history.
