In the human heart, the left ventricle is the one that pumps freshly oxygenated blood into the aorta, and from there into the rest of the body. The new lab-grown model could offer researchers a ...

University of Toronto researchers in the Faculty of Applied Science & Engineering have grown a small-scale model of a human left heart ventricle in the lab. The bioartificial tissue construct is made ...

Double inlet left ventricle (DILV) is a rare condition and its exact etiology is currently unknown. It occurs in 5 to 10 out of 100 000 births. It is suspected to be due to abnormal development of ...
