Three-year-old baby has heart murmur

If you find that your three-year-old baby has a heart murmur during a check-up, you should do further examinations so that you can get an accurate diagnosis of their condition. Usually, abnormal test results will be caused by lesions inside the heart. The more serious ones are heart disease, left heart failure and other critical diseases, which will completely threaten your baby's life once they occur.

(A) Apical systolic murmur

Non-pathological apical systolic murmur, rheumatic mitral valvulitis, rheumatic mitral regurgitation, infective endocarditis, rheumatoid heart disease, systemic lupus erythematosus, scleroderma, papillary muscle insufficiency or chordal rupture, (coronary heart disease, myocardial infarction), idiopathic chordal rupture, valvular relaxation, mitral valve prolapse syndrome, Marfan syndrome, hypertrophic obstructive cardiomyopathy, dilated cardiomyopathy, atrial septal defect, patent ductus arteriosus, endocardial cushion defect, pregnancy, hyperthyroid heart disease, anemic heart disease, beriberi heart disease, athlete's heart syndrome, high altitude heart disease, third degree atrioventricular block, carcinoid syndrome, left heart failure, aortic regurgitation, relative mitral regurgitation.

(ii) Apical diastolic murmur

Rheumatic mitral valvulitis, rheumatic mitral stenosis, infective endocarditis, rheumatoid heart disease, systemic lupus erythematosus, aortic regurgitation Austin-Flint murmur, left atrial myxoma, large mitral valve vegetation or thrombus, constrictive pericarditis, Hurler syndrome, patent ductus arteriosus, Lutembacher syndrome, severe mitral regurgitation, severe aortic regurgitation, ventricular septal defect with large shunt, hypertensive heart disease, aortic coarctation, dilated cardiomyopathy, anemic heart disease, hyperthyroidism heart disease, third degree atrioventricular block, apical diastolic murmur caused by other reasons.

(III) Systolic murmur in the aortic valve area

Rheumatic aortic valvulitis, rheumatic aortic stenosis, aortic atherosclerosis, hypertensive heart disease, supravalvular aortic stenosis syndrome, congenital bicuspid aortic valve, aortic coarctation, syphilitic aortitis, aortic aneurysm, Ebstein's anomaly, severe aortic regurgitation, complete atrioventricular block, hyperthyroid heart disease, anemic heart disease, carcinoid syndrome, carotid murmur, and systolic murmur in the aortic valve area caused by other reasons.

(IV) Diastolic murmur in the aortic valve area

Rheumatic aortic valvulitis, rheumatic aortic regurgitation, syphilitic aortic regurgitation, infective endocarditis, rheumatoid heart disease, systemic lupus erythematosus, Marfan syndrome, aortic atherosclerosis, aortic valve ring enlargement caused by hypertension, rupture of aortic sinus aneurysm, high ventricular septal defect causing aortic valve prolapse, and aortic valve regurgitation caused by other reasons.
