Figure 2 Postoperative color Doppler echocardiograms. A: Postoperative color Doppler echocardiogram, acquired on June 8, 2019, revealing mild aortic regurgitation (arrow). The lateral cystic echo of the aortic valve was narrower than that of the anterior aortic root, observed on May 20, 2019. The left ventricular systolic function was normal; B: Postoperative color Doppler echocardiogram, acquired on July 3, 2019, revealing mild aortic regurgitation (arrow). The lateral cystic echo of the aortic valve was enlarged compared with that of the previous echocardiogram (June 8, 2019). The left ventricular systolic function was normal.
