Abstract
A successful case of surgical treatment of a patient with low-flow, low-gradient severe aortic stenosis with significantly reduced contractility of the left ventricular myocardium (LV ejection fraction 17%) is presented. During the preoperative diagnosis, in addition to standard studies, dobutamine stress echocardiography was performed to confirm the presence of a flow reserve and to exclude pseudo-severe aortic stenosis. The patient underwent aortic valve replacement with a mechanical prosthesis Carbonix № 26 and ascending aorta repair using Robicsek procedure. Patient has uncomplicated postoperative period. The patient was discharged 10 days after surgery. At the time of discharge, an increased left ventricular contractility was noted (up to 28%). Changes in contractility parameters and the function of the implanted prosthesis in dynamics in the long-term period (more than 36 months) were also studied.
