==Answer==
Answer d. A biscupid aortic valve is seen in 80% of coarctations. Noonan
syndrome is associated with pulmonary stenosis. Williams syndrome is
associated with supravalvular aortic stenosis, and Tetralogy of Fallot is
associated with a boot-shaped cardiac silhouette on x-ray. Pre-operative pacing
is not required for asymptomatic Mobitz type I AV block, but is required for
Mobitz type II block.
