Abstract

Objective: To analyze the correlation between left ventricular parameters on 128-slice computed tomography images compared with 2D transthoracic echocardiography in patients undergoing coronary computed tomography.

Subjects and methods: retrospective descriptive study on 150 patients assigned to have coronary computed tomography scan at Military Hospital 175 on 128-slice computed tomography machine from September 2022 to May year 2023.

Results: There was a linear correlation between left ventricular end-diastolic volume, left ventricular end-systolic volume, ejection volume, left ventricular ejection fraction, diastolic diameter, and systolic diameter on micrographs. coronary artery and on echocardiography (rho = 0.836, p<0.001). Diastolic volume, systolic volume and ejection volume as measured by computed tomography were greater than those on echocardiography with the difference of 1.23 ± 14.4 ml, 2.46 ± 3.95 ml, -1.14 ± 12.98 ml, respectively. There was no difference in the results of left ventricular ejection fraction as assessed by computed tomography compared with echocardiography. Difference: -1.94 ± 4.99 ml, p= 0.302>0.05.

Conclusion: Estimation of left ventricular volume and left ventricular ejection fraction by coronary computed tomography imaging is feasible and correlates well when compared with echocardiography.
