Abstract

Background. The review traces the main successes and problems in reconstructive surgery of aortic valve defects with a narrow fibrous ring of the aortic valve. Objective: to study the problem of patient-prosthesis mismatch (PPM) in the surgical treatment of the aortic valve defect with a narrow fibrous ring and the ways to overcome this problem. Material and methods: literature sources on this subject by domestic and foreign authors were analyzed. Results. Patient-prosthesis mismatch is a risk factor for patients undergoing aortic valve replacement and is associated with poor hemodynamic and symptomatic status. Conclusion. Surgeons should make every effort to prevent the occurrence of PPM. However, it is possible to prevent PPM using new generation prostheses, frameless bioprostheses (for example, Perceval) or allografts while performing the Osaki operation or its modification, or expanding the aortic valve ring in order to implant a larger prosthesis.
