Various disorders of the cardiovascular system include Dressler’s syndrome, uremia and endocrine diseases. Diagnosis is using radiology in which the shift in position and volume of blood in the aorta, pulmonary artery, vena cava, ventricles, auricles of the human heart is studied. Differential diagnosis of cardiovascular disorders includes pericardial effusion of pericardial fluid greater than 50ml. In cases of hypertension the pressure in the arteries is greater than 30mm Hg as in case of pulmonary arterial hypertension which is congenital in a few cases. Enlarged atrium leads to tricuspid regurgitation and enlarged ventricle to total or partial anomalous pulmonary venous return due to volume overload. Enlarged superior vena cava leads to supracardiac total anomalous pulmonary venous return due to high volume and bronchogenic carcinoma due to obstructive causes.
