I37.1: Pulmonary valve insufficiency

Your pulmonary valve is leaking.

The heart pumps blood through the body. Inside the heart are 4 chambers. There are 2 heart atria and 2 ventricles. Both heart atria and both ventricles are separated from each other by a partition. There are 4 valves in the heart. These valves ensure that the blood flows in the right direction. So they have to close tightly. They also have to open up fully so that the blood can be properly pumped out of the heart.

The pulmonary valve is the valve between the right ventricle and the pulmonary arteries. Your pulmonary valve is no longer closing properly. If the pulmonary valve is not closing properly, blood can flow back through the valve each time the heart beats. The heart then has to work harder to pump enough blood to the lungs. You may have various symptoms as a result. The symptoms depend, for example, on how much blood is flowing back through the leaky valve. One may be short of breath, and feel weak or tired.
