[Calcinosis and its meaning in heart surgery]

The paper presents the analysis of calcinosis frequency and expressivity of calcinosis revealed during surgical treatment of 598 patients with acquired heart defect. In operative interventions under EKG conditions calcinosis was observed in 25% cases, and in performance of closed mitral commissurotomy in 36.7%. Retrospective analysis of special features of the illness course in 346 patients with rheumatic mitral defect accompanied by predominant stenosis in dependence on presence and degree of stenosis expessivity. The role of calcinous conglomerates as chronic intracardiac infection reservoirs is noted.
