If pulmonary edema continues, it can raise pressure in the pulmonary artery (pulmonary hypertension), and eventually the right ventricle in your heart becomes weak and begins to fail. The right ventricle has a much thinner wall of muscle than does the left side of your heart because it is under less pressure to pump blood into the lungs.
When the heart is not pumping well, it can cause a backup of blood. This backup of blood causes fluid to leak from the blood vessels into the tissues. This is called congestion.. In the lungs, congestion may lead to difficulty breathing. In the ankles and legs, the congestion or backup of fluid causes swelling.
