Abstract

Objective - to assess the capabilities of intraoperative transesophageal echocardiography in patients with different forms of coronary heart disease (CHD), identify the echocardiographic predictors of early postoperative complications.

Material and methods . The study included 92 patients with CHD. Depending on the form of the disease the patients were divided into 2 groups: the first group included 23 patients with uncomplicated coronary heart disease, the second group of 69 patients with coronary artery disease complicated by postinfarction left ventricular aneurysm.

Results . Analysis of the obtained echocardiographic parameters were allowed to establish regularities and to identify the predictors that characterize the smooth and complicated course of early postoperative period. Patients on the background of a smooth flow, there is a trend towards normalization of the volume characteristics of the left ventricle (LV), improving the pumping function of the myocardium (increase of LVEF 7%), normal levels stroke and cardiac indexes, the absence of haemodynamically significant dysfunction of the atrioventricular valves. The General pattern of adverse flow included a decrease in the pumping function of the LV myocardium, cardiac and stroke indices of LV, increase of the degree of mitral and/or tricuspid insufficiency. On the basis of data obtained by intraoperative transesophageal echocardiography, in 10% of cases was changed tactics of surgical intervention. 8% of patients after the main phase of the operation was diagnosed dysfunction of the myocardium, determined by etiology of heart failure and in accordance with the adjusted tactic anesthesia and the hemodynamic management.

Conclusion . Thus, intraoperative transesophageal echocardiography in patients with various forms of CHD is a universal diagnostic tool which can modify the operations plan quickly diagnose myocardial dysfunction, and to analyze, allowing time to influence the way in surgical tactics and management of hemodynamics.
