This method is based on the ability of the ultrasound to be reflected from tissues with different density (myocardium, valve apparatus, scar tissues, fluid) and consists in capturing and transferring of the ultrasound signal sent and reflected from various heart structures into a picture.
The main aim of this procedure is to evaluate not only the structural but also the functional state of the heart muscle. To get the required information medical specialists use specific ultrasound device - the obtained data is displayed on the monitor so that even patient could see and hear how his or hers heart works.
During echocardiography, cardiac physiologists measure heart cavities and the thickness of myocardium, determine if there are intracavitary clots and aneurysms of the heart walls or damage of the valve apparatus, and any pathological blood flows.
The procedure helps assess the systolic and diastolic functions of heart, intra-cardiac pressure, as well as find any congenital deformities of the heart and determine their intensity. Echo is one of the most common diagnostic methods used in cardiology; it is indispensable in making and clarifying such diagnoses as acute and old myocardial infarction, congenital and acquired valvular diseases, cardiomyopathies, pericardium disorders, myocardial tumors, heart failure etc.
Sometimes simply referred to as, Doppler, the modern method of ultrasound diagnostics (Doppler Echocardiography) helps detect pathological changes in blood vessels.
The Doppler method measures the change in frequency of ultrasound waves bouncing off of blood cells (the Doppler Effect).
This procedure makes it possible to measure and register different blood flow parameters, evaluate the condition of the vessel wall and heart valves, vascular permeability, blood flow state and velocity, detect various conditions of blood vessels (e.g., Roughness and constrictions.) The Doppler method is harmless and not invasive.
Normal blood flow in the vessels may be broken due to various reasons, but by means of the Doppler method a whole set of parameters can be analyzed, and that helps diagnose cardiovascular diseases such as ischemic heart disease, aortic aneurysm, portal hypertension, and atherosclerotic vascular disease) with maximum accuracy in their early stages.
