Information

Hyperdynamic, enlarged LV; the PDA can often be visualized on two-dimensional echo; Doppler demonstrates abnormal flow through it.

Treatment: Patent Ductus Arteriosus

In absence of pulmonary hypertension, PDA should be surgically ligated or divided to prevent infective endocarditis, LV dysfunction, and pulmonary hypertension. Transcatheter device closure is frequently possible.
