What is Pulmonary Regurgitation?

Also known as: PR, pulmonic regurgitation, pulmonary incompetence, pulmonary insufficiency

The pulmonary valve controls the flow of blood from the heart out to the lungs. When this valve leaks, it allows blood to flow backward into the heart before it can travel to the lungs. This leak is known as pulmonary regurgitation and it can be categorized as mild, moderate or severe.
