ABSTRACT
Echocardiography is a procedure through which ultrasound is applied to the heart in order to obtain and view images. At present, it is the most useful non-invasive heart study because of its harmlessness, easiness and reproducibility characteristics. It can be performed through the transthoracic or transesophageal techniques on repose or through cardiac stimulation. According to variation in the signal code, images from M mode, B mode, 3-D, pulse Doppler, continuous Doppler and tissue Doppler can be obtained. The main indications are the heart murmur evaluations, even the inorganic ones, when it is not possible to exclude cardiovascular disease through other methods. Another indications are given by the measurements of the width of myocardium walls, left ventricular function, cardiac procedure, left ventricular segment motion, etc. During the procedure performance, it is convenient to first do the transthoracic approach and follow the American Society of Echocardiology guidelines to obtain the different orthogonal planes through different “windows”, which have to be taken in a methodical and routine way.
