Abstract

Abstract

            The left ventricular ejection fraction (LVEF) is an important and influenced parameter to describe systolic function. The normal value of LVEF in a healthy population is above 55%, and based on magnetic resonance imaging(MRI) and transthoracic echocardiography (TTE). This study aimed to compare the different LVEF from both methods by a paired t-test and correlation. In 54 clinical stable patients, aged between 4 to 37 years of age, 54% were male, and 46% were female who underwent MRI and TTE for a duration of 10.7 + 8.2 months. The results showed that the LVEF from TTE (M-Mode) was greater at a statistically significant than the MRI, at 66.7 + 7.1% vs. 60.3 + 8.8% [95% CI=9.14 - 3.70] and showed weak positive correlation (r= 0.23, p-value< 0.05). Although the MRI is the gold standard to measure left ventricular ejection fraction, but the TTE is important in deprived areas because of the simplified method and the economic aspect of lower costs. TTE is one choice to measure LVEF, which users should know about, particularly the differences and the properties of both tools.
