Features of rheumatic heart disease in newborns

What is rheumatic heart disease in children? I believe many parents have this question: Why do children get rheumatic heart disease? What are the characteristics of neonatal rheumatic heart disease? How to treat it? I believe many parents want to know the answer. Heart disease is a disease that is relatively harmful to the human body. Today we will talk about the characteristics of neonatal rheumatic heart disease!

(1) Heart murmur: A prominent heart murmur is the most important feature of carditis, most of which is caused by mitral valve and aortic valve lesions. In children, 90% suffer from mitral valve disease, less than 10% suffer from aortic valve damage, and more than half suffer from combined mitral and aortic valve disease. During auscultation, the most common murmurs heard are the systolic blowing murmur caused by mitral regurgitation and the mid-diastolic rumbling murmur caused by mitral stenosis.

(2) Changes in heart sounds and heart rate: The first heart sound becomes low and dull, which may be related to carditis and prolonged atrioventricular conduction time. The valve is in a higher position before closing and is close to closing. The diastolic gallop rhythm is often heard. An increase in heart rate that is often out of proportion to the increase in body temperature and that does not slow down during sleep. Even long after the carditis has been controlled, the heart rate remains high.

(3) Cardiac enlargement: Physical examination reveals that the apex beat exceeds the mid-clavicular line, or there is an obvious heart beat under the xiphoid process, indicating an enlarged heart. The shape of a child's heart changes greatly, especially during exhalation and inhalation. In addition, the pulmonary artery cone may be prominent in normal children, but the right ventricle may not necessarily be enlarged, so clinicians should not ignore this. When heart disease is extensive, the heart becomes diffusely enlarged, often with murmurs. From a prognostic point of view, an enlarged heart is more important than a murmur.

Through the introduction above, I believe you already know the characteristics of neonatal rheumatic heart disease! If you find any abnormality in your child's body, you should go to the hospital for examination in time. Rheumatic heart disease is mostly caused by repeated fever after suffering from pharyngitis and pharyngitis, which can cause systemic allergic immune response diseases. Parents should take care of their children carefully and cautiously.
