Heart valves allow blood to flow one way and prevent it from flowing in the wrong direction. The tricuspid valve controls blood flow between the right atrium and right ventricle. The bicuspid or ...

Through dissection of the gene expression changes in the right atrium, the study provides a snapshot into the molecular mechanisms underlying major cardiovascular diseases. These insights could pave ...
