Subacute aortic regurgitation due to traumatic tear in the aortic wall.

ABSTRACT: A 37-year-old man presented with heart failure caused by severe aortic regurgitation (AR). He had a history of being involved in a traffic accident 3 months earlier. Imaging tests at admission detected no abnormalities in the aortic valve or aortic wall; however, the left coronary cusp prolapsed slightly on transthoracic echocardiography. He underwent aortic valve replacement because of uncontrolled heart failure and severe AR. Intraoperatively, the intima of the aortic wall just above the commissure of the left and right coronary cusps was torn to the short axial direction. Local aortic tear was the final diagnosis for the subacute AR. <Learning objective: Acute or subacute aortic regurgitation (AR) is comparatively rare, and it is sometimes difficult to clinically recognize. The tear in the aortic wall just above the commissure caused by a traffic accident led to the gradual progression of AR, and the diagnosis of the cause of AR was difficult despite using transesophageal echocardiography and contrast-enhanced computed tomography. We should recognize that the detection of subacute AR caused by a local aortic tear can be challenging.>.
