[The syndrome of mitral regurgitation in patients with chronic heart failure].
Functional mitral regurgitation is a frequent complication of severe course of ischemic heart disease and plays a role of no small importance in origin and progression of chronic heart failure (CHF). Severe degree of mitral regurgitation is found in 18.9%, moderate - in 29.7% of patients with systolic left ventricular dysfunction. A major precondition for origin of mitral regurgitation is the presence of the process of left ventricular remodeling which disturbs coordination between the ventricle and valvular apparatus. Changes of anatomo-functional state of the mitral valve occurring during its closure determine severity of mitral regurgitation in patients with CHF and left ventricular dysfunction.
