Pulmonary regurgitation (PR, also called pulmonic regurgitation) is a leaky pulmonary valve. This valve helps control the flow of blood passing from the heart to the lungs. A leaky pulmonary valve allows blood to flow back into the heart chamber before
it gets to the lungs for oxygen.

What are the symptoms of pulmonary regurgitation?
With this particular valve condition, there are usually no early symptoms that would be noticed by the patient. Signs that can be detected in a medical exam include a certain type of murmur heard when
the heart is between heart beats.
Eventually, whether due to the valve problem or the pulmonary hypertension that may have caused the valve problem, the lower right chamber of the heart can become enlarged. Rarely, these conditions can progress to heart failure which can create more noticeable symptoms such as chest pain or discomfort, fatigue, lightheadedness or fainting.
How is pulmonary regurgitation treated?
Treatment for PR is usually focused on the underlying cause that created the valve problem (i.e. pulmonary hypertension). The need to replace the pulmonary valve is very rare.
