Complicated aortic root enlargement in a patient who underwent aortic valve replacement

For patients with a small aorta, surgeons may use techniques such as the Manouguian method in addition to aortic valve replacement (AVR) to prevent patient prosthetic mismatch. These methods have been shown to have good outcomes and few complications. However, in this case presentation, a rare complication occurred in a 47-year-old woman who underwent AVR plus Manouguian surgery. After the surgery, her echocardiography revealed iatrogenic supra-aortic stenosis. The diagnosis was confirmed with computed tomography angiography, and the patient underwent surgery again at the site of the stenosis. Fortunately, the surgery was successful, and the stenosis was completely resolved.
