Echocardiogram or Cardiac Ultrasound is also referred to as ECHO. A standard procedure employs ultrasound techniques to give 3D real-time images of the heart. The 3D images provide cross-section view of all chambers, valves and blood vessels that run from the left to right side of the heart. This basic medical procedure is used in case of patients with heart tumors, abnormal heart rate, to check blood flow blockage in valves, leakage in valves, or any inflammation of the heart lining. This diagnostic procedure is very expensive and in US price of a heart echocardiogram varies from $1,150 to $4,200.
