Overview
Most uncommon cause of left ventricular outflow tract obstruction accounting for 8% of congenital LVOT obstruction.
Anatomy
- Obstruction occurs just above the coronary ostium at the level of the sinotubular junction:
- Hourglass type (the most common)
- Hypoplastic type: uniform narrowing of the ascending aorta.
- Associated lesion is peripheral pulmonary arterial stenosis
- Because of high perfusion pressure of the coronary arteries there is premature CAD.
- Coronary arteries may be obstructed by an adjacent stenotic ring.
Clinical Features
- 1/3rd of cases are transmitted as an autosomal dominant trait.
- 50% have a characteristically greater pulse and systolic blood pressure in the right carotid and brachial arteries than in the left.
- The systolic murmur is maximal below the right clavicle and radiates primarily to the right carotid artery.
- No ejection click, no diastolic murmur.
