Comparison of the assessment of left ventricular ejection fraction by Teichholz and Simpson’s method

Abstract

Introduction: Left ventricular ejection fraction (LVEF) has been used for many years to assess left ventricular systolic function. Over time, patients may have LVEF measurements performed with the use of different imaging modalities.Ejection fraction measurements obtained with both the Teichholz and Simpson's methods are directly comparable for evaluation of ejection fraction.This study is done to compare Teichholz method to simpson's method in patients with global hypokinesia of left ventricle. Methods: Prospective cross sectional study was done in 150 patients who underwent echocardiography at Chettinad Super Speciality hospital. Using conventional 2D echocardiography and Doppler Echocardiography left ventricular ejection fraction was assessed in various views (Apical four chamber, Apical two chambers and parasternal long axis) using VIVID S5 and Esaote.From the total subjects, 105 patients were male and 45 were females. In this study, we compare Teichholz method to Simpson's method in patients with global hypokinesia of left ventricle. Results: Out 150
