Overview
Chest X-ray findings associated with aortic regurgitation may include left ventricular enlargement, cardiomegaly, prominent aortic root with valvular calcification, prosthetic valve dislodgement, or aortic dilation. If aortic regurgitation is severe, signs of pulmonary edema may also be present.[1]
Chest X-Ray
In patients with aortic regurgitation, chest radiograph may demonstrate any of the following findings:[1][2][3]
- Cardiomegaly
- Aortic dilation
- Increased cardiac silhouette (suggestive of aortic dissection)
- Widened mediastinum (suggestive of aortic root dilation)
- Pulmonary congestion (suggestive of pulmonary edema or pulmonary hypertension in severe AR)
- Prominent aortic root
- Aortic valve calcification
- Prosthetic valve dislodgement
Shown below is a chest radiograph demonstrating left ventricular enlargement secondary to chronic aortic regurgitation as a result of increased left ventricular systolic pressure and volume overload.
