Echocardiography - a method of ultrasound diagnosis applied to studies of functional and morphological changes in the heart and its structures. This method of diagnosis to assess the condition of the heart valves in the visualization mode. Echocardiogram widely used for early diagnosis of cardiac diseases that enables time to identify pathology.
Indications for echocardiography of the heart
An ultrasound of the heart is indicated for:
- Noise and varying degrees of localization in the heart;
- Feverish condition of uncertain cause;
- Detection of ECG changes;
- Suspicion for the presence of congenital or acquired heart disease;
- They appear on the radiograph - with an increase in heart size or structure, a modified aortic calcification cluster;
- Arrhythmias, including perceived;
- Hereditary serious pathologies of the cardiovascular system;
- The complaint to the fainting, chest pain, swelling of the legs, a strong shortness of breath and frequent dizziness;
- Increased blood pressure;
- Myocardial infarction;
- Suspected of having a tumor of the heart, as well as the expansion of the thoracic aorta.
Echocardiography of the heart reveals the presence of tumors and diagnosing various lesions. In addition, an echocardiogram is used to monitor the state in coronary artery disease, congenital heart disease, after suffering a heart attack, with cardiomyopathy and hypertension.
It is also recommended to undergo echocardiography of the heart at regular sports training and other activities, causes increased stress on the heart, or at a constant emotional stress. In childhood, in the process of rapid development and growth of the child, especially in cases of suspected congenital heart disease, also assigned an echocardiogram.
Congenital heart defects, which are a major cause of perinatal mortality, can be diagnosed by fetal echocardiography. This procedure is harmless to the fetus and to evaluate intracardiac hemodynamics in the prenatal period, and also to carry out dynamic control parameters during pregnancy in identifying systolic heart murmur. This method echocardiogram of the heart and blood vessels is often used to assess the condition of the child before birth, allowing early diagnosis and begin treatment almost immediately after birth. Fetal Echocardiography detail examines the heart and blood vessels, revealing inborn errors in his work.
If necessary, fetal echocardiography is performed at 18 - 22 weeks of pregnancy. Indications for diagnosis are:
- Congenital heart disease in relatives;
- Miscarriages before the current pregnancy;
- Taking antibiotics and drugs for epilepsy in the first trimester;
- Deviations recorded for a planned fetal ultrasound at 20 weeks.
Decoding Fetal echocardiography is performed by cardiologists or physician-geneticist.
Methods of echocardiography of the heart
Depending on the indication echocardiography of the heart can be performed in several ways to assess the various options:
- Echocardiography M-mode - the size of the heart and systolic ventricular performance;
- Two-dimensional echocardiography - wall thickness and size of heart chambers, ventricular contractility, the state of the valves, as well as the presence or absence of thrombosis cavities;
- Transesophageal - a rear wall of the heart, usually after myocardial bottom wall of the heart;
- Intravascular ultrasound - the state of the coronary vessels;
- Solid modeling of the heart;
- Doppler study - the center speaker;
- Stress - changes in various segments of the heart caused by physical exertion;
- Contrast echocardiography - a condition of the heart chambers.
Decoding echocardiography carries cardiologist. On the basis of the diagnosis can be more than a starting researcher and computational performance and objectively evaluate:
- Status and function of the valves;
- The functional state of the myocardium;
- The presence of intracardiac thrombus;
- Indicators pump function and left ventricular dynamics;
- The dimensions of the cavities of the heart;
- The thickness of the walls of the heart;
- The presence of scarring;
- The degree of hypertrophy of the heart chambers.
Contraindications to echocardiography
Echocardiography - a safe diagnostic procedure that has no absolute contraindications. However, when chest deformation that impedes the normal diagnosis, as well as certain allergic and inflammatory skin lesions in the heart, its implementation may be difficult.
