Overview
Pulmonary valve regurgitation is a condition where the pulmonary valve is not strong enough to prevent backflow into the right ventricle. Nearly all individuals have physiologic (trace-to-mild) pulmonic regurgitation, and the incidence increases with advancing age. Hence, there is a backward flow of blood from the pulmonary artery, through the pulmonary valve, and into the right ventricle of the heart during diastole.
Historical perspective
The pulmonary valve and its function of allowing blood to the lungs for nourishment was first described by Hippocrates. Erasistratus, mentioned the involvement of the pulmonary valve in the unidirectional flow. Realdo Colombo described the pulmonary circulation for the first time.[1]
