The Y-incision aortic annular enlargement allows implantation of prosthetic valves 3-4 sizes larger, improving effective orifice area to better match patient anatomy.
This review highlights common technical errors and early outcomes associated with the Y-incision aortic annular enlargement technique to accommodate larger prosthetic valves during surgical aortic valve replacement.

Studies have shown that the effective orifice diameter of surgical prosthetic valves is 5-7 mm smaller than the labeled valve size. To improve outcomes of surgical aortic valve replacements, the Y-incision aortic annular enlargement enlarges the surgical aortic annulus to accommodate a prosthetic valve 3-4 sizes larger with an effective orifice area that matches the patient's basal ring. This review described the common mistakes of performing the Y-incision aortic annular enlargement in surgical aortic valve replacement, with a detailed look at early outcomes.
