What can cardiac color ultrasound detect?

Cardiac color ultrasound (echocardiography) is a non-invasive, safe examination method that uses ultrasound imaging to evaluate the structure and function of the heart. it can clearly showHeart size, ventricular wall thickness, valve opening and closing status, blood flow direction and speed, is a diagnosisCongenital heart disease, cardiomyopathy, pericardial disease, heart failurekey tools. Secondary inspections includeCardiac function assessment, intracardiac thrombus or tumor screening, but for coronary artery stenosis, it needs to be combined with other tests.

Core inspection content: structural and functional assessment

The primary task of cardiac color ultrasound is to observeThe shape and movement of the four chambers of the heart (left/right atrium, ventricle), to measure whether the ventricular wall thickness is abnormal (such as hypertrophic cardiomyopathy). Evaluate simultaneouslyvalve function, such as mitral stenosis or regurgitation, showing disturbed blood flow via color Doppler. In addition, it can detectpericardial effusionOr thickened, assisting in the diagnosis of pericarditis.

Hemodynamics and special lesion screening

Through Doppler technology, color ultrasound can quantifyBlood flow speed, direction and pressure difference, to help judgeCongenital defect (such as atrial septal defect) or degree of valvular disease. forHeart tumors (such as myxoma) or blood clots, Color Doppler ultrasound can clearly display the location and size of space-occupying lesions, but attention must be paid to identifying artifacts.

Limitations and the need for joint examinations

Cardiac color ultrasound cannot directly observecoronary artery stenosis(Coronary CTA or angiography is required), yesminimal myocardial ischemiaLess sensitive. Some patients may need to combineCardiac MRI or CT. Dynamic assessment, such as stress ultrasound, can improve the detection of occult disease.

Summary and clinical application value

Cardiac color ultrasound is used to diagnose cardiovascular diseasescornerstone check, especially good atStructural abnormalities and hemodynamic analysis. Its non-radiation and reproducible characteristics are suitable for long-term follow-up, but it needs to be combined with other methods according to the condition. Commonly used in clinicalPreoperative evaluation, postoperative review and chronic disease monitoring, providing accurate basis for treatment plan.
