[Morphofunctional state of the heart in dilated cardiomyopathy in children]
Insights
Echocardiography reveals significant cardiac chamber dilation and impaired function in children with dilated cardiomyopathy (DCMP). These findings help assess heart damage severity for treatment and prevention strategies.
Area of Science:
- Pediatric Cardiology
- Cardiovascular Imaging
- Cardiac Pathophysiology
Context:
- Dilated cardiomyopathy (DCMP) is a serious cardiac condition affecting children.
- Accurate assessment of cardiac function is crucial for managing pediatric DCMP.
- Echocardiography is a primary diagnostic tool in pediatric cardiology.
Purpose:
- To evaluate the morphofunctional cardiac state in children diagnosed with dilated cardiomyopathy.
- To characterize echocardiographic findings associated with pediatric DCMP.
- To understand the implications of these findings for treatment and prognosis.
Summary:
- Echocardiography in 49 children (1-15 years) with DCMP showed significant cardiac chamber dilation.
- Moderate myocardial hypertrophy (primarily left ventricle) and impaired contraction/relaxation were observed.
- Relative mitral valve failure was common, impacting hemodynamics, though echographic changes are not specific to DCMP.
Impact:
- Echocardiographic findings provide insights into the severity of cardiac damage in pediatric DCMP.
- This assessment is vital for guiding treatment strategies and prophylactic measures.
- Understanding these morphofunctional alterations aids in managing hemodynamic derangements and improving patient outcomes.
Abstract:
To study the morphofunctional state of the heart, 49 children aged 1 to 15 years with dilated cardiomyopathy (DCMP) were examined. The diagnosis was established on the basis of comprehensive clinical and instrumental examinations. It was discovered as a result of echocardiography that children with dilated cardiomyopathy show considerable dilatation of the cardiac chambers, accompanied by moderate hypertrophy of the myocardium (mainly of the left ventricle) and by appreciable impairment of the function of myocardial contraction and relaxation together with derangement of heart pump function. The overwhelming majority of patients with DCMP manifested relative failure of the mitral valve which plays an important role in the impairment of intracardiac and central hemodynamics. It should be noted that echographic alterations seen in DCMP are not specific. However, they provide an idea of the gravity of heart damage, that is of importance in outlining the policy of treatment and prophylactic measures.
