Left Ventricular Reverse Remodeling Evaluation After Surgical Correction of Aortic Regurgitation

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.
