Abstract:
Objective To evaluate the data of preoperative aortic root CT angiography (CTA), compare it with two-dimensional transthoracic echocardiography and investigate the correlation of the two measurements with the actual intraoperative measurement data. Methods Clinical data of 53 patients with aortic valve diseases who underwent aortic valve repair in our hospital from January 2018 to August 2020 were retrospectively analyzed, including 38 males and 15 females with an average age of 42.9±18.3 years ranging from 10 to 77 years. Preoperative two-dimensional transthoracic echocardiography (TTE) and aortic root CTA measurements were collected, including aortic valve annulus (AVA), aortic sinus (Sinus) and sino-tubular junction (STJ). In comparison with the intraoperative measurements during the aortic valve repair surgery, the consistency analysis was performed. Results Both the preoperative echocardiography AVA measurements and the CT AVA measurements were positively correlated with the intraoperative AVA measurements (P<0.001). Compared with the echocardiography AVA data [correlation coefficient (ρ)=0.74, mean squared error (MSE)=12.78], the CT AVA data were more accurate and consistent with the intraoperative AVA measurements (ρ=0.95, MSE=2.72). CT AVA data had a higher correlation coefficient with the intraoperative measurements, compared to that of the echocardiography AVA data (P<0.001). Conclusion In comparison with two-dimensional transthoracic echocardiography, preoperative morphological evaluation of aortic root CTA is more consistent with the actual intraoperative measurements during aortic valve repair surgery.
