Prevalence and Severity of Mitral Valve Regurgitation in Patients with Systolic Left Ventricular Dysfunction

Abstract

background: Functional mitral regurgitation may develop in patients with congestive heart failure due to left ventricular systolic dysfunction, which is common, costly and lethal syndrome. Echo-Doppler is an extremely sensitive tool for the detection of mitral regurgitation.Objective: To determine theprevalence and severity of functional mitral regurgitation in patients with left ventricular systolic dysfunction using echocardiography.BSetting : Al-Hussain Hospital echocardiography clinic in Karbala city.Methods: One hundred sixty patients were divided into two groups: Group A: constituted of 80 consecutive patients who had a left ventricular ejection fraction <40% and group B: constituted of 80 consecutive patients who had a left ventricular ejection fraction >40%.The study patients underwent standard echocardiogram. Severity of mitral regurgitation was graded as mild, moderate and severe.Results: In patients with left ventricular systolic dysfunction (group A), mitral regurgitation was more common. It was mild in 22.5%, moderate in 52.5% and severe in 21.25%.Conclusion: The majority of patients with left ventricular systolic dysfunction had mitral regurgitation .Echo-Doppler should be included in the evaluation of these patients.
