Can congenital subvalvular aortic stenosis be cured?

summary

Congenital subvalvular stenosis accounts for 3% ～ 8% of the cases of congenital left ventricular outflow tract obstruction, second only to aortic stenosis. It has two common types: (1) localized subvalvular stenosis accounts for 70%, and diaphragm like subvalvular stenosis, which is caused by a fibrous diaphragm 1.0 ～ 1.5cm below the aortic valve, And fibromuscular septal subvalvular stenosis (localized stenosis caused by fibrous septum and fibromuscular thickening). Can congenital subvalvular aortic stenosis be cured? Let's talk about it

Can congenital subvalvular aortic stenosis be cured?

Asymptomatic infants do not need surgical treatment, only when the systolic pressure gradient of stenosis is more than 50 mmHg, ECG shows severe left ventricular hypertrophy, strain, or secondary infection with endocarditis. Patients with left heart failure and sudden death often have malformations, so they should be operated actively.

Ross Konno procedure is suitable for patients with complex subvalvular stenosis and aortic ring or aortic stenosis, but they are too young to undergo aortic valve replacement.

Konno procedure is suitable for patients with aortic ring stenosis or aortic stenosis who need aortic valve replacement. The modified Konno procedure is suitable for patients with severe subvalvular stenosis, difficult to remove obstruction through aortic incision, and normal aortic ring and aortic valve.

matters needing attention

Diet should not be too full, keep the stool unobstructed, should eat less and more meals, pay attention to eating vegetables and fruits with more fiber, keep the stool unobstructed, use kaisailu and glycerin suppository when necessary. When feeding babies, choking and coughing should be prevented. Those who have difficulty in sucking should be fed by dropper or nasal feeding.
