Assessment of ventricular function is paramount for the diagnosis of heart failure. objective of this study was to evaluate the left ventricular function in Yaounde using the CT scan. Methods. We carried out a retropective cross sectional and describtive study on data collected from November 2016 to July 2019 at the medical imaging service of Centre Medical la Cathedrale of Yaounde. We included all cardiac CT scan patient files with at least one systolic and diastolic phase. We excluded all the files of patients with arrhythmias. Left ventricular function was evaluated using direct volume measurement. Results were presented with means and standard deviations. The Kappa coefficient of Cohen with confidence intervals for measurements of left ventricular ejection fraction by two observers evaluated inter-observer reproducibility. Results. The mean telediastolic volume of the left ventricle was 102,76 ± 33,48 ml/m2 and the mean telesystolic volume 38,09 ± 16,60 ml/m2. The mean left ventricular systolic ejection fraction 55,93 ± 14,36\%. Left ventricle dysfunction was found in 22\% of the patients. We found an inter-observer concordance regarding left ventricular ejection fraction measurement with a Kappa coefficient of 0.63. Conclusion. One quarter of the study population showed Left ventricular dysfunction. We observed a good concordance in the assessment of left ventricular ejection fraction.
