While engineered heart tissues can replicate muscle contraction and electrical activity in a dish, many aspects of heart disease can only adequately be captured in 3D. In a report published online yesterday by Nature Biomedical Engineering, researchers describe a scale model of a heart ventricle, built to replicate the chamber’s architecture, physiology and contractions. Cardiac researchers at Boston Children’s Hospital think it could help them find treatments for congenital heart diseases.
