Aortic Stenosis (AS) is a narrowing or tightening of the aortic valve. This narrowing prevents the blood from passing through the valve effortlessly. There are several degrees of AS, mild, moderate and critical (severe). In many instances of the mild to moderate form, the child was asymptomatic, but was found to have a murmur on examination. There are three areas where the aortic valve can become stenotic.
A heart/lung machine or medication may be required for the surgical procedure. While the surgical techniques for each of these valvular narrowing’s are different, the objective is still the same, to relieve the obstruction.
Most children do very well after the procedure. Invasive lines are present to monitor blood pressure (arterial/venous), chest tubes, pacing wires in place. Many will be on vasodilators, i.e., nitroprusside, nitroglycerin. Hemodynamic instability is not uncommon in the immediate postoperative period requiring volume support.
