Echo Color Doppler

Echo or cardiac ultrasonography is a method of diagnosis which, like other types of ultrasound, is based on the use of the ultrasonic waves. The investigation is easy to be carried out (do not require any special preparation prior notice may be made at any time of the day, does not imply any kind of discomfort for the patient), noninvasive (does not imply punching a patient or another way of aggression on he) and devoid of risks.

Unlike the other investigations involving the use of radiation protection (radiography, CT, NMR), the penetration in the circulatory system of the patient dangerous puncture (catheterization, coronarografie or in such other hollow sections using the endoscopic instruments (endoscopy colonoscopy, cistoscopia, etc.), echo can be repeated as frequently without affecting
with anything that patient.

Indications

Indications Echo thus represents a method of diagnosis indispensable today cardiology, with the following:

  • diagnosis and tracking in the dynamics of the valvular affection;
  • diagnosis congenital cardiac malformations ;
  • detection of tumors and other parties intercardiace;
  • diagnosis of diseases of the pericardium;
  • monitoring of the valvular prostheses ;
  • tracking patients operate with aortocoronarian bypass;
  • monitoring of treatment compared hypertensive patients, with if chronic cardiopathy painful, with angioplasty transluminala vertebroplasty with fitting the stent, with acute myocardial infarction;
  • tracking patients with various types of cardiomyopathies.

What is the test?

Cardiac Ultrasonography has become a routine method in the diagnosis, the appreciation of the severity of guidance and treatment for most develop cardiovascular diseases. It is used in both cardiovascular emergencies and chronic diseases, any consultation current bakuev assuming carrying out this investigation.
Echo involves the placement of a device with the ultrasound transducer (transducer) on the patient's chest,with which the clinician can to view on the monitor the structure and the bundle its heart and thus can identify any abnormalities of the fillet and the valves of the heart.

There are several ways of ultrasound examination: ultrasonography in M-Mode, two-dimensional ultra sonography, the examination of the Pulsed Wave Doppler, Spectral (continuous) and color and tissue Dopplerul. All of these ways give additional information and are used for an assessment complete heart block, successively or simultaneously.

Ultrasonography in M mode has occurred with the development of this diagnostic methods and play the movement of the heart structure pursued in time. It is characterized by the temporal resolution very good and it is used and at present to carry out with more accuracy of measurements: the size of the heart cavities, various distances, wall thickness, ejection fraction or
shortening etc.

Ultrasonography 2D or two-dimensional allows you to view all of the cardiac structures: bad camshaft or heart cavities (atria and ventriculi), the valves that separate rooms (cavities) cardiac, pericardium (membrane which wrap heart), the vessels are connected with the heart (pulmonary veins and hollow Artery, Aorta and the pulmonary artery). Thus, the two-dimensional ultrasonography provides information about the morphology of the heart structures (dilation of the cavities, hipetiei
(cardiac muscle contractility of the heart or of the myocardium), reveals the presence of fluid in the pericard or of abnormal structures at the level of the heart cavities (blood clots – vasculitis or tumors). Diagnoses accurately the rupture of the walls or
intimei numerous artery (total dissection of aorta), or the various congenital malformation rates etc.

The examination of the Doppler (Pulsed Wave, whether continuous or color) allows viewing and measuring the speed of the blood flow inside the heart cavities and of the blood vessels and the carrying out of the hemodynamic measurement is useful for detecting insuficientelor or stenoses valvulare (in these cases the speeds of the circulation of the blood are much reared)
or quantifying the severity of them (valvulopatii or valvulare disorders, cardiomiopatii, pulmonary hypertension, etc.)

Tissue Doppler is a way of the Doppler examination developed in recent years that do not have than modern ultrasound high-performance and which is assessed with high accuracy of the systolic and diastolic spressures cardiac, being extremely useful in the assessment of the severity of the heart disease.
