摘要

We present a case of a 9-year-old boy with severe aortic insufficiency and left ventricular dilatation. The patient underwent aortic valve replacement with annular enlargement using a modified Nicks technique. This approach successfully enlarged the aortic annulus, enabling the implantation of a larger prosthesis. The procedure was performed without any complications, offering a potential surgical strategy to prevent postoperative patient-prosthetic mismatch in pediatric patients with aortic valve disease.
