Bio-Artificial Heart and Tissue Engineering

Dr. Sean Wu discusses the history and future of heart prosthetics, focusing on the development of bioartificial hearts. He highlights the limitations of current devices like the left ventricular assist device and explores the potential of stem cells and 3D printing in creating functional heart tissues. The talk emphasizes the need for innovative solutions to address the growing demand for heart transplants.
