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.
1 Heart failure. 2  When the heart is unable to maintain adequate blood flow throughout the circulatory system, the excess fluid pressure within the blood vessels can cause shifts into the interstitial spaces. 3  Left-sided heart failure can cause pulmonary edema, as fluid shifts into the lungs.
