[Phenomenological Regularities of Assessment of Left Ventricle Function in Mitral Valve Insufficiency].

Objective: to examine relationship between anatomical changes of the left ventricle (LV), dynamics of velocity of its volume modification, and blood flows in the LV in patients with mitral regurgitation (MR) before and after surgical treatment.

Materials And Methods: We included into this study 58 patients with severe 3-4 degree MR (38 men, 20 women aged 24-69 [mean age 51±9] years) in sinus rhythm (96 %) or atrial fibrillation (4 %). The control group included 86 healthy volunteers, mean age 39±7 years.

[Modeling of hemodynamic changes in the aneurysm of the middle cerebral artery depending on the pathology of the parent artery].

Objective: To examine the influence of the parent artery pathology on the local hemodynamics on the level of aneurysm.

Material And Methods: Mathematical models of the arteriovenous malformation (AVM) were built on the CT-angiography data of real patients. To simulate the thrombosis, the parent artery and its branches were sequentially turned off in the model 1.

[PREDICTORS OF RISK OF SURGERIES IN PATIENTS WITH FAILURE OF THE CORONARY CIRCULATION].

The paper analyzes the study of the myocardium in patients with coronary artery disease to identify new predictors of reduction of myocardial contractility. Research carried out on the basis of transthoracic echocardiography and transesophageal on Vivid 7 unit and Vivid-E9 with multifrequency array sensor (3.5-5.

[ASSESSMENT OF EXTRAVASCULAR LUNG WATER BY QUANTITATIVE COMPUTER IMAGE ANALYSIS IN PATIENTS WITH ACUTE RESPIRATORY DISTRESS SYNDROME].

Purpose: To evaluate the possibility of quantitative computed tomography (CT) of the lungs in patients with acute respiratory distress syndrome (ARDS) for assessment of the severity of the condition and the effectiveness of treatment.

Materials And Methods: The study included 29 patients with ARDS and 22 with no signs of lung disease (control group). We measured extravascular lung water (EVLW) by transpulmonary thermodilution (TTD) and analysed CT of the lungs in patients with ARDS.
