Area of Science:

Cardiovascular Surgery
Biomedical Engineering
Regenerative Medicine

Background:

Current aortic valve prostheses include bioprosthetic and mechanical options with distinct limitations.
Bioprosthetic valves face tissue deterioration, while mechanical valves require lifelong anticoagulation.
Tissue engineering presents a novel approach to heart valve replacement.

Purpose of the Study:

To provide an overview of the current development of tissue-engineered aortic heart valves.
To highlight the potential of regenerative tissue-engineered valves in cardiovascular applications.
To discuss the challenges and future directions for tissue-engineered aortic valves.

Main Methods:

Review of current literature on tissue-engineered heart valve development.
Analysis of existing studies on tissue-engineered valves in right ventricular outflow tract reconstruction.
Evaluation of limited experiences with tissue-engineered valves in the systemic circulation.

Main Results:

Tissue-engineered heart valves demonstrate potential for remodeling, regeneration, and growth.
Successful applications of tissue-engineered valves are documented in right ventricular outflow tract reconstruction.
Limited but emerging data exists on their use in the systemic aortic position.

Conclusions:

Tissue-engineered aortic heart valves represent a next-generation solution overcoming current prosthesis limitations.
Further research and clinical investigation are needed for widespread adoption in systemic circulation.
Regenerative capabilities offer a significant advantage over traditional prosthetic heart valves.
