Figure 1. (A) Echocardiography showed moderate or severe aortic regurgitation at the time of the patient’s admission. (B) Two months later, echocardiography showed that the patient’s left ventricular ejection fraction had improved to 37% and aortic regurgitation had improved from moderate to mild status. (C) Transesophageal echocardiography revealed that the patient’s aortic regurgitation was stronger at the gap between the coronary cusp and the aorta rather than at the apex of the valve (arrow). (D) Aortic wall lesions similar to those seen on computed tomography were also observed on transesophageal echocardiography (arrow).
