Brief summary
Investigators assume that surgical correction approach to functional mitral regurgitation during intervention for chronic aortic regurgitation in patients with severe enlargement of the left heart chambers influences reverse remodeling of the left ventricle (LV) in the postoperative period. It is suggested that functional mitral regurgitation (MR) provides supra-physiological left ventricle volume overload and this fact plays positive role in early-stage post-operative left ventricle volume and function recovery. LV volume, systolic and diastolic function will be monitored with echocardiography (EchoCG) along with life quality in patients with different grades of functional mitral regurgitation secondary to severe chronic aortic insufficiency after surgical treatment of aortic regurgitation.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| LV end-diastolic volume (EDV) decrease | 3 and 12 months after surgery | Change in end-diastolic volume of the left ventricle, assessed with EchoCG after surgical correction of aortic insufficiency |
| Freedom from readmission | 12 months after surgery | Freedom from readmission due to valvular problem or heart failure-related reason |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Life quality | Upon inclusion, 10 days post-surgery, 3 month and 12 month post-surgery | The patient's life quality according to the results of the EuroQol-5D-5L (EQ-5D-5L) questionnaire (0-100 points, the higher - the better). |
Other
| Measure | Time frame | Description |
|---|---|---|
| LV ejection fraction (EF) | 3 and 12 month post-surgery | Left ventricle ejection fraction, assessed with EchoCG |
| LV diastolic function | Upon inclusion, 3 month and 12 month post-surgery | Left ventricle diastolic function, assessed with EchoCG |
| Left atrium volume index (LAVI) | Upon inclusion, 3 month and 12 month post-surgery | Left atrium volume indexed to body surface area, assessed with EchoCG |
