[A mechanical heart valve prosthesis with a spherical shape and open center]

Area of Science:

• Biomedical Engineering
• Cardiovascular Devices
• Prosthetic Valve Technology

Context:

• Previous mechanical heart valve generations (I and II) caused blood flow obstruction and turbulence.
• These hemodynamic issues led to undesirable clinical consequences.
• The Simkovic-Bolf valve featured a central opening to improve flow, but further advancements are needed.

Purpose:

• To introduce a new generation III mechanical valve prosthesis.
• To improve upon existing designs by ensuring central blood flow.
• To reduce blood trauma and myocardial stress through optimized hemodynamics.

Summary:

• A novel mechanical valve prosthesis of generation III is described, featuring a central blood flow design.
• Unlike earlier generations that obstructed flow and caused turbulence, this valve maintains laminar flow.
• The design aims to minimize damage to blood components and reduce stress on the heart muscle (myocardium).

Impact:

• Potential to improve patient outcomes by reducing complications associated with mechanical heart valves.
• Offers a more hemodynamically efficient alternative to existing prosthetic valves.
• Contributes to the advancement of cardiovascular device technology.
