    Area of Science:

    • Biomedical Engineering
    • Cardiovascular Science
    • Materials Science

    Background:

    • Biomedical engineering significantly influences the design, development, and testing of artificial heart valves.
    • It also plays a crucial role in the pre- and post-operative care of patients with cardiac valve disease.

    Purpose of the Study:

    • To review heart valve replacement procedures.
    • To enhance future contributions from bioengineering in this field.

    Main Methods:

    • Review of patient management approaches for valvular heart disease.
    • Analysis of early and late postoperative pathology, focusing on prosthetic complications.
    • Identification of key problem areas in cardiovascular function evaluation, device design, hemodynamics, and material science.

    Main Results:

    • Significant challenges exist in noninvasive cardiovascular function evaluation (pre- and post-surgery).
    • Device design and hemodynamic performance are critical areas for improvement.
    • The development of thromboresistant and durable materials remains a major concern.

    Conclusions:

    • Further bioengineering innovation is needed to address current limitations in heart valve replacement.
    • Focusing on material science, device design, and advanced diagnostic techniques will improve patient outcomes.
