[Injuries to myocardium in infectious endocarditis].

Clinical and morphological characteristics of myocardium in infectious endocarditis (IE) are described as exemplified by pathological changes in the vascular bed, stroma, and myofibrils.

[Development of targeted indicators of quality in postmortem examination].

The indicators of quality for impartial quantitative assessment of postmortem examination have been suggested. These indicators were based on ratio of achievement and target indexes of pathologicoanatomic activity. The indicators are necessary for decision making for enhancement of pathologicoanatomic service quality in the health-care agencies.

[Primary (idiopathic) cardiomyopathies].

The lecture gives the clinical and morphological characteristics of different forms of primary (idiopathic) cardiomyopathies. It presents macroscopic, histological, and ultrastructural changes in primary cardiomyopathies.
