3D Printed Prosthetic Heart Valve

Heart valve replacements are life-saving procedures essential for patients with dysfunctional heart valves. The global market for prosthetic heart valves is valued at approximately USD 8.71 billion in 2024, with devices available in various forms, including mechanical, transcatheter, and biological valves used for both replacement and repair procedures. While traditional prosthetic valves have improved survival, they present several limitations that contribute to postoperative complications over time. These include limited durability, the need for long-term anticoagulation due to clot formation linked to immune responses, mechanical valve noise (often described as clicking or squishing sounds), the inability to accommodate growth in pediatric patients, and suboptimal anatomical fit for certain individuals with complex health conditions. Moreover, common complications associated with these valves include stroke, bleeding, and leakage around valve flaps following surgery. In contrast, emerging 3D printed heart valves, fabricated from advanced co-polymers, show promise in early laboratory studies, demonstrating excellent tissue compatibility and the potential to reduce or eliminate the need for lifelong blood-thinning medications
