What are the indications of pulmonary regurgitation?

When it comes to this valve condition, there are no early symptoms present. The indications that might be detected in a medical assessment usually include a certain form of murmur that can be heard once the heart is between heartbeats.

Over time, whether due to a valve issue or the pulmonary hypertension might be responsible for the valve condition, the lower right chamber of the heart can end up enlarged. In rare instances, these conditions can later develop to heart failure which triggers more evident symptoms such as chest pain or discomfort, lightheadedness, fatigue or fainting.

Management

The treatment for pulmonary regurgitation is generally aimed on the underlying cause responsible for the valve condition. There are instances where the pulmonary valve is replaced but this is considered rare.
