    A novel surgical technique allows for the implantation of larger aortic prosthetic valves by widening the aortic root with pericardium. This method was successfully used in all 12 patients who underwent the procedure.

    Area of Science:

    • Cardiovascular Surgery
    • Medical Devices
    • Surgical Innovation

    Background:

    • Aortic valve replacement is a common cardiac procedure.
    • Implantation of larger prosthetic valves can improve hemodynamics.
    • Limited space in the aortic root can restrict prosthesis size.

    Purpose of the Study:

    • To describe a new surgical technique for aortic valve replacement.
    • To facilitate the insertion of larger aortic prosthetic valves.
    • To evaluate the feasibility of this novel approach.

    Main Methods:

    • A surgical method involving widening the aortic root using pericardium.
    • Slightly oblique insertion of the aortic prosthetic valve.
    • Application of the technique in a clinical setting.

    Main Results:

    • The described surgical technique was successfully applied in all 12 attempted cases.
    • This method enables the insertion of a relatively larger aortic prosthetic valve.
    • No complications were mentioned in the abstract.

    Conclusions:

    • The described surgical technique is a feasible approach for aortic valve replacement.
    • This method allows for the implantation of larger prosthetic valves.
    • The technique demonstrated success in all patients where it was attempted.
