Study note

Persistent ductus arteriosus: anatomy and investigations

THE CONTEXT

A persistent ductus arteriosus connects the aorta and pulmonary artery, with left-to-right shunting.

•

The persistent ductus forms a connection between the aorta and pulmonary artery, permitting left-to-right shunting.

•

Echocardiography is the investigation of choice.

•

Specific echocardiographic views, such as a view from the suprasternal notch, are required to reveal the persistent ductus.

•

The target text describes electrocardiographic evidence of right ventricular hypertrophy.
