title: Simultaneous echocardiographic recording of the semilunar valves in patients with normally related great arteries.
abstract: On the echocardiograms of 2 infants with normally related great arteries, both semilunar valves were recorded simultaneously, a finding previously thought to be specific for d-transposition of the great arteries. Neither patient had d-transposition; in both cases the diagnosis was proved by cardiac catheterization.
