PSN4 merits preclinical valve testing; leaves open translation to durable human implants.
Computational modeling suggests that the PSN4 nanocomposite is a highly suitable material for artificial heart valves due to its superior strength, flexibility, and low energy consumption.
Shaukat Ali (2023) studied Valvular heart disease. PSN4 nanocomposite material vs. Other synthetic materials (PETG, PLA, nylon, TPE, TPU, SIBSTAR103T) was evaluated on Biomechanical performance (equivalent stress, strain energy, total deformation, stress safety factor). The PSN4 nanocomposite material demonstrated the best biomechanical performance for manufacturing artificial heart valves, yielding the highest stress safety factors and lowest deformation rates.
