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 They have thicker walls than the atria, and they create higher blood pressures to pump blood out of the heart into circulation to the body and the lungs.  The right ventricle pumps deoxygenated blood into pulmonary circulation. The left ventricle pumps oxygenated blood into systemic circulation. The left ventricle is thicker because systemic circulation involves a much larger blood volume than pulmonary circulation.
