Possibility of ultrasound examination of abdominal organs, musculoskeletal system, thyroid, mammary gland. Perform a transcranial triplex scan.
Echocardiography – The method of ultrasound diagnostics aimed at the study of morphological and functional changes in the heart, valve apparatus, and main vessels.
Indications for Echocardiography are any symptoms that may indicate cardiopathology. Echocardiography is also performed in patients after acute cerebral circulation disorder with suspicion of a cardioembolic subtype of ischemic stroke (search for a cause). This diagnostic method allows you to identify and monitor the congenital and acquired heart valve defects, diagnose additional shunts, septal defects, diagnose cardiomyopathy, detect heart changes and complications in hypertensive disease, coronary heart disease. This method is shown as control after heart and major vessel surgery, deep vein thrombosis, chemotherapy in oncology, suspicion of aortic aneurysm. Also, the indication for Echocardiography is a chronic headache, the presence of hereditary diseases in relatives of the first line (for example, hypertrophic cardiomyopathy and many others.) An example of visualization of valvular pathology, in the comparison format: stenosis – norm, is shown in Fig.1
Fig.1 Echocardiography in case of valvular lesion. Fig. 1 A and Б stenosis of the aortic valve; in Figure 1. В and Г for comparison valve without pathology when locating in the same access. Fig.1 A – parasternal access, long axis of the left ventricle, option Zoom. The aortic valves are densified, the degree of valve opening is reduced (indicated by an arrow). Fig.1 Б – parasternal access, short axis at the level of the aortic valve, option Zoom. The aortic valve is open. The arrow indicates the remaining hole.
Echocardiography is a rapid, accurate and non-invasive method in the presence of congenital heart defects. In Fig. 2 Echo signs of an open arterial (botallov) duct.
Fig. 3 – defect of the interatrial septum.
Fig.2 Congenital heart disease: open arterial duct. Parasternal access, short axis, color Doppler mapping mode. ЛА – pulmonary artery. Ao – aorta. The arrow indicates the blood flow (discharge of blood) from the open arterial (botallov) duct
Fig.2 Atrial septal defect. Parasternal access, short axis at the level of the aortic valve, color Doppler mapping mode. The arrow indicates the blood flow through the defect, the left-right discharge. Ao – aorta. ПП – right atrium, ЛП – left atrium.
