Treatment of aortic stenosis in infants

After a child is born, the hospital's examination can determine the child's congenital disease. If a child has a congenital disease, the treatment effect will be best at the earliest. The baby's aortic artery stenosis is also one of the heart diseases. Any heart disease has a great impact on the child. Heart disease is a sudden death that is unknowing, and even parents are not aware of it. So how to treat baby's aortic aortic stenosis?

1. Patients with asymptomatic mild aortic stenosis require regular and close follow-up. ① Those with rheumatic activity should receive anti-rheumatic treatment; ② Prevent infective endocarditis during dental, gastrointestinal and genitourinary tract surgery and instrument examinations. Antibiotic prophylaxis should be given.

2. Treatment for patients with symptomatic aortic stenosis: ① Limit physical activity to prevent worsening syncope or sudden death; ② Accompanied by ventricular stenosis.

Surgery

In case of tachycardia, high-degree atrioventricular block and severe sinus bradycardia, antiarrhythmic drug treatment should be used (see Arrhythmia for details); ③ Patients with chest pain need coronary angiography to diagnose concomitant coronary heart disease. In this case, sublingual nitroglycerin should be used. Note that the dosage should be small to prevent excessive dosage on the basis of the existing reduction in cardiac output, which may cause peripheral arterial dilation and lead to syncope; or further reduce coronary blood flow due to decreased arterial pressure; ④ Diuretics can be used in case of left ventricular failure. However, the dosage should not be too large, so as not to reduce cardiac output.

3. Indications for percutaneous balloon aortic valvuloplasty and artificial aortic valve replacement (1) Patients with a history of recurrent syncope, angina pectoris, or left heart failure that has been controlled by drugs. (2) Aortic valve area <0.7 cm: transvalvular pressure gradient ≥50 mmHg. (3) The valve itself is fully developed and congenital or acquired stenosis is caused by adhesions at the commissure. (4) No obvious calcification of the valve: may be accompanied by mild regurgitation.

If the baby's heart has aortic stenosis, use these methods to treat the child. If the aorta is stenotic, surgery must be performed in time to clear the child's heart to avoid adhesion of the heart artery. After the aorta is cleared, the stenosis can be improved in time. It is also a kind of care for the child's heart. The child's emotions should not be overly excited at ordinary times.
