Congestive heart failure (CHF) is the result of insufficient output because of cardiac failure, high resistance in the circulation or fluid overload. Left ventricle (LV) failure is the most common and results in decreased cardiac output and increased pulmonary venous pressure. In the lungs LV failure will lead to dilatation of pulmonary vessels, leakage of fluid into the interstitium and the pleural space and finally into the alveoli resulting in pulmonary edema. Right ventricle (RV) failure is usually the result of long standing LV failure or pulmonary disease and causes increased systemic venous pressure resulting in edema in dependent tissues and abdominal viscera. In the illustration on the left some of the features, that can be seen on a chest-film in a patient with CHF. #Diagnosis #Radiology #CHF #CXR #Features #Findings #Diagram #RadiologyAssistant
