The Evolution of Cardiac Prosthetic Devices: From Concept to Care

Key takeaways

• Introduction
• Integrating advanced materials to improve performance
• A wave of personalized devices
• Technological evolution in prosthetics
• Innovative products for advanced care

Cardiac prosthetic devices include various implants such as mechanical and bioprosthetic heart valves, annuloplasty rings, ventricular assist devices (VADs), and artificial hearts. These devices are surgically placed within the heart or blood vessels to replace or support damaged or diseased cardiac structures, ensuring proper circulation and cardiac function.

Patients with congenital heart defects often need cardiac prosthetic devices to address issues with heart valves, septa, or other structures. In severe cases of coronary artery disease, where the heart muscle is extensively damaged, devices like artificial hearts are considered as a treatment option. When the heart’s pumping ability is compromised, ventricular assist devices (VADs) are used to temporarily support or replace the heart’s function, potentially serving as a link to a heart transplant.

The growing prevalence of cardiovascular diseases, including heart valve disorders, coronary artery disease, and heart failure, is a key factor driving the cardiac prosthetic devices market. With the aging global population and the increasing prevalence of lifestyle factors such as obesity, physical inactivity, and poor diet, the demand for cardiac prosthetic devices is steadily rising.

Enhancing heart valve function with advanced polymers

Recent advancements in 3D printing technology have led to the use of both organic and synthetic polymers in the fabrication of heart valves. These materials are being refined to enhance biocompatibility and functional performance. Natural polymers such as collagen, fibrin, and chitosan are especially significant due to their potential to promote tissue regeneration, a key factor in developing durable and effective implants.

The potential of 3D bio-printed heart valves

The emergence of 3D bioprinting is a groundbreaking development, enabling the creation of functional heart valves that can seamlessly integrate with the body tissues. This technique involves printing scaffolds that are infused with patient-derived cells, potentially resulting in fully functional, biologically active valves that eliminate the need for artificial substitutes.

Improving device performance with myoelectric control systems

Myoelectric prostheses, associated with upper-limb prosthetics, are now being investigated for applications in cardiovascular devices. Electrical signals from muscle activity can control these devices, and they have the potential to enhance patient outcomes in cardiovascular care greatly.

These prostheses use electromyographic (EMG) signals produced by muscle contractions to control movement. This technology is applied to cardiovascular devices, such as ventricular assist devices (VADs), allowing for more intuitive control that reflects the patient's physiological condition. By incorporating myoelectric controls, these devices can adjust their operation in real time, responding to the user's needs and improving overall performance.

Furthermore, recent advancements have enabled the integration of myoelectric prostheses with wearable health monitoring systems. These systems are able to track vital signs and offer insights into heart function, improving the management of cardiovascular conditions. For example, a myoelectric-controlled pacemaker can adjust its pacing based on real-time muscle activity or physical exertion levels detected by wearable devices.

The advent of new devices with enhanced features

Healthcare device manufacturers are heavily investing in research and development to improve device performance, durability, and patient outcomes. They are also expanding globally through geographic growth and mergers and acquisitions. Meanwhile, emerging players targeting niche segments like tissue-engineered heart valves and minimally invasive delivery systems are promoting innovation, creating a dynamic landscape in the industry. For instance, in February 2023, Royal Philips, a leading company in health technology, revealed a long-term collaboration with TriHealth, an integrated healthcare system based in Cincinnati.

As part of this partnership, TriHealth implements Philips' comprehensive cardiology solutions at their new TriHealth Heart & Vascular Institute, situated at Bethesda North Hospital and the Harold and Eugenia Thomas Comprehensive Care Center.

In summary, advancements in cardiac prosthetic devices, such as better materials, customized implants, and muscle-controlled technology, are helping patients with heart diseases. These innovations are essential in addressing the increasing global demand for effective treatments for heart failure, valve disorders, and other cardiovascular conditions.
