Right-sided heart failure
Results in congestion of abdominal organs causing hepatomegaly, splenomegally distended caudal
vena cava and jugular veins, pericardial effusions and ascites or intrathoracic
effusions. Peripheral oedema rarely occurs.
Tricuspid insufficiency, cor pulmonale and neoplasia of the right side of the heart are the geriatric diseases which would most likely cause right heart
failure in the UK, but the pulmonary hypertension that occurs with left-sided heart
failure may result eventually in right-sided failure as well. In enzootic areas
heartworm can also cause right heart failure at any age.
