Background and Aim：This study aimed to compare the results of 2D transthoracic echocardiography (TTE) and cardiac computed tomography (CT) in the evaluation of left ventricular function, and to determine the effectiveness of cardiac CT as well as whether it can serve as an alternative to TTE.
Materials and Methods：A total of 29 patients who underwent cardiac CT for suspected coronary artery disease between June and August 2016 and also had TTE examinations were retrospectively analyzed. Measurements including ejection fraction (EF), end-diastolic volume (EDV), and end-systolic volume (ESV) were obtained using the modified Simpson method with both modalities.
Results: The mean EF (67.48 ± 7.79%) and EDV (128.06 ± 28.34 mL) values obtained by CT were significantly higher than those measured by TTE (63.64 ± 3.86% and 98.45 ± 27.98 mL, respectively) (p=0.018 and p<0.001, respectively). No statistically significant difference was observed between the two methods in ESV measurements (TTE: 36.13 ± 12.90 mL; CT: 39.96 ± 14.57 mL; p=0.430).
Conclusion: Although TTE remains the primary method for the evaluation of left ventricular function due to its accessibility, cardiac CT provides a valuable alternative by offering functional data, particularly in patients with limited acoustic windows.
