The liver and the heart are closely related organs connected by large vessels. Thus, the heart may be affected by liver diseases, leading to cardiac overload, pulmonary hypertension or high-output heart failure. Severe or chronic liver diseases may result in several heart or pulmonary complications independent of any other existing cardiac or lung diseases in the patient. The major causes are cirrhosis, non-cirrhotic portal hypertension, congenital portosystemic shunts, hereditary haemorrhagic telangiectasia and congenital liver hemangioma. These liver diseases lead to various degrees of cirrhotic cardiomyopathy, vasoactive imbalance or high-flow cardiopathy. High blood flow, shunts and cardiac dilatation predominate on imaging. In the presence of a vasoactive imbalance, the hepatopulmonary syndrome and portopulmonary hypertension must be differentiated. The aim of this review was to describe the diagnostic and imaging features of heart and lung complications from liver diseases.
