[Left ventricular dysfunctions after correction of aortic stenosis].

The purpose of the investigation was to study central hemodynamics and left ventricular function in low cardiac output after correction of aortic stenosis. The study included 34 patients (28 males and 6 females) aged 59. 7+/-1.

[The plasma level of an inactive moiety of B-type natriuretic peptide precursor as a predictor of cardiac function during operations under extracorporeal circulation].

Ventricular cardiomyocytes secrete brain natriuretuc peptide (BNP) and an inactive moiety of its precursor (nt-proBNP). It is recommended the blood level of the latter should be monitored to ascertain the severity of myocardial lesion. This investigation was undertaken to study the diagnostic and prognostic value of a substantial increase in blood nt-proBNP levels (600 pg/ml or more) in patients operated on under extracorporeal circulation.

[Anesthetic management of the surgical correction of heart valve defects combined with myocardial revascularization].

Thermodilution volumetry of the right ventricle (RV) in the course of combined operations has demonstrated significance of RV function and identified signs of its dysfunction when other parameters of hemodynamic monitoring were low informative. Of late, introduction of updated anesthetic modalities and intraoperative monitoring have noticeably improved surgical outcomes of combined lesions of the heart as shown by decreased hospital lethality.
