1. Normally aortic valve has 3 leaflets; when it is having 2 leaflets then it is known as bicuspid aortic valve; when having one leaflet then known as unicuspid aortic valve.
2. Subvalvular aortic stenosis can be due to fibrous ridge, membrane below aortic valve etc. Besides obstruction below the aortic valve, the most common issue that occurs with this variety of aortic stenosis is that it damages the aortic valve leaflets also.
3. Supravalvar aortic stenosis generally occurs with a syndrome known as ‘Williams’s syndrome’. It can be in the form of hourglass shape or funnel shaped type of obstruction.
Diagnosis of Aortic Stenosis
It can be suspected on examining the child but best modality for detection of aortic stenosis is by Pediatric Echocardiography.

Management of Aortic Stenosis
- Treatment of aortic stenosis (AS) depends on severity of obstruction.
In mild to moderate obstruction, patient needs medical follow-up at periodic intervals most of the time.
In severe obstruction, patient needs immediate intervention for resolving the obstruction.
In Valvular aortic stenosis, treatment of choice is by doing balloon dilatation of Aortic valve’’.
