Cardiogenic pulmonary edema is primarily caused by left ventricular (LV) noncompliance. When the left ventricle is unable to properly fill or eject blood, pressure increases in the left atrium and pulmonary veins, leading to fluid leakage into the pulmonary interstitium and alveoli, causing pulmonary edema. Elevated PAOP readings, RV chamber enlargement, and pulmonary hypertension are not primary causes of cardiogenic pulmonary edema but can be related to other cardiac conditions.
