Key result
Y-incision aortic annular enlargement permits prosthetic valves 3-4 sizes larger to improve effective orifice area.
Why the study?
Surgical prosthetic valves have effective orifice diameters 5-7 mm smaller than labeled sizes, prompting the Y-incision annular enlargement to accommodate larger valves.
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.
May warrant consideration to prevent PPM in SAVR; extends literature by detailing common technical errors and associated early outcomes.
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.
