The first aortic valve repair was performed in 1958, but the clinical outcome was limited. Since the invention of prosthetic valves, aortic valve replacement has become and still maintained the dominated surgical treatment option. As the impact of the prosthetic valve-related event to quality of life of the patients and the studies of the mechanism of aortic regurgitation and the functional anatomy of aortic root grow, the application of aortic valve repair gets more popular, and the short- and mid-term outcomes are good.
ObjectiveTo 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.MethodsClinical 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.ResultsBoth 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 squarederror (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).ConclusionIn 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.
