Echocardiography provides information regarding cardiac morphology, function and hemodynamics non-invasively. It is the most frequently performed cardiovascular examination after electrocardiography and chest X-ray. In less than half a century, this technique has evolved to a mainstay of cardiovascular medicine. The historical evolution of echocardiography is succinctly described including that of M-mode, two-dimensional, Doppler, stress, transesophageal, intraoperative, contrast, digital, three-dimensional and intracardiac echocardiography.
