Key result
Y-incision aortic annular enlargement allows larger prostheses in small annuli without affecting mitral geometry.
Why the study?
The study describes the Y-incision aortic annular enlargement technique to enable implantation of significantly larger prostheses and avoid prosthesis-patient mismatch without affecting mitral geometry in patients with small aortic annuli.
The Y-incision aortic annular enlargement technique enables the implantation of larger prostheses during aortic valve replacement to avoid prosthesis-patient mismatch.
The Y-incision aortic annular enlargement technique offers a reliable solution for the aortic valve replacement in patients with small aortic annuli. By enlarging the annulus and root using a Y-incision and rectangular patch, this technique enables implantation of significantly larger prostheses to effectively avoid prosthesis-patient mismatch without affecting mitral geometry. Based on our experience using minimally invasive access, tailored patch design, modified closure of aortotomy, and integration with ascending aortic replacement when needed, the technique is reproducible and adaptable. Early outcomes are promising, though long-term follow-up and multicenter comparison are required to evaluate its benefits and potential risks.
