MAGNETIC RESONANS IMAGING AS A MODERN METHOD IN PREDICTING THE OUTCOME OF REVASCULARIZATION PROCEDURES ON THE LEFT VENTRICLE OF HEART IN EARLY POSTOPERATIVE PERIOD

The purpose. Demonstrate the capabilities of magnetic resonance imaging (MRI) of heart as a modern imaging technique in the diagnosis of surgical treatments on the heart left ventricle (LV) in the early postoperative period.

Materials and methods. With the help of MRI in the dynamic («Cine») scan was an assessment of the functional parameters of the left ventricle of the heart: end-systolic, end-diastolic volume (ESV, EDV) and ejection fraction (EF) to revascularization and after 2–3 weeks after intervention interference. Then there were two groups of patients with increasing and decreasing LV EF in the early postoperative period, where by subsequently conducted a comparison of volume indices in patients before and after surgery.

Results. In the period up to 2–3 weeks after revascularization improvement of myocardial contractility was observed in 57 % of patients. The group with an increase in ejection fraction compared with the preoperative value LV EDV value decreased by 19 % and ESV LV – 22 %. The group of patients with a decrease in LV EF after surgery LV EDV decreased by 15 %, and the value of ESR by 8 %. In the postoperative period in patients with an increase in ejection fraction traced LV EDV values decrease by 1,3, and CSR LV by 2,8 in alignment with those parameters in a group of patients with reduced ejection fraction after revascularization surgery.

Conclusion. Due to data obtained by MRI heart doctor may have valuable information about the patient’s condition, which allows to predetermine in the early postoperative period, the severity of left ventricular improve the functional status, which gives an opportunity not only to assess the quality of the operation, but also allows us to predict a positive or negative result of revascularization in the late postoperative period.
