👉 Dipleurule is a term used in medicine to describe a type of heart valve that allows blood flow from one ventricle (right atrium) to another ventricle (left atrium), but not to the other ventricle. This condition can cause a decrease in blood flow and, as a result, can lead to heart failure. The term "dipleurule" is derived from the Latin word "dipleurus," which means "double-ventricular valve."
