Aortic annular enlargement using the Y-incision technique-How I do it

Area of Science:

• Cardiovascular Surgery
• Cardiac Surgery Innovations
• Aortic Valve Repair

Background:

• Aortic valve replacement in patients with small aortic annuli presents challenges.
• Prosthesis-patient mismatch is a significant concern, potentially impacting long-term outcomes.
• Current techniques may have limitations in addressing small aortic root dimensions.

Purpose of the Study:

• To present the Y-incision aortic annular enlargement technique as a solution for aortic valve replacement in small aortic annuli.
• To evaluate the feasibility and early outcomes of this novel enlargement technique.
• To assess the impact of the technique on prosthesis size and prosthesis-patient mismatch.

Main Methods:

• The Y-incision technique involves enlarging the aortic annulus and root using a specific incision and a rectangular patch.
• Minimally invasive access, tailored patch design, and modified aortotomy closure were employed.
• Integration with ascending aortic replacement was performed when necessary.

Main Results:

• The Y-incision technique successfully enabled the implantation of significantly larger aortic prostheses.
• The technique effectively avoided prosthesis-patient mismatch.
• Mitral valve geometry was not adversely affected by the annular enlargement.
• Early outcomes were promising, demonstrating reproducibility and adaptability.

Conclusions:

• The Y-incision aortic annular enlargement technique is a reliable method for aortic valve replacement in patients with small aortic annuli.
• This technique facilitates the use of larger prostheses, mitigating prosthesis-patient mismatch.
• Further long-term follow-up and multicenter studies are warranted to fully establish the benefits and risks.
