The Specific Features of an Early Period after Minimally Invasive Cardiac Surgery

Objective: to comparatively evaluate the perioperative clinical period in patients operated on via miniinvasive access and median sternotomy.

Subjects and methods. A retrospective analysis included all patients who had undergone correction of mitral valve defect with or without tricuspid valve correction and atrial ablation. 121 and 112 patients were operated on through miniinvasive access (a study group) and median sternothomy (a control group), respectively.

Results. The duration (median [25; 75 percentiles] of aortic occlusion in the study group (89 [71; 120] min) was significantly longer than that in the control group (65 [52; 84] min); р<0.01. Acute heart failure complicated the clinical course in 28 (23.1%) and 15 (13.4%) cases in the study and control groups, respectively; р=0.06. In the miniinvasive
access group, two deaths were caused by intraoperative aortic dissection. There was no significant difference in the length of stay in the intensive care unit and in that of hospitalization between the groups.

Conclusion. The findings are generally correlated with the world data obtained while implementing the procedure. The frequency and pattern of complications due to miniinvasive correction of mitral valve defect require additional financial expenditures and human resources. It is necessary to analyze the longterm results of treatment for the reasonable evaluation of the efficiency and expediency of using this procedure.
