Overview

The findings on chest x ray depends on the degree of shunting between left and right system.

Chest X Ray

Occasionally, the ductus can be seen as a separate convexity between the aortic knob and the pulmonary artery segments.^[2]
Cardiomegaly related to left atrium and left ventricular volume overloads.
Increase in the pulmonary vascular markings.
The ascending aorta may be prominent due to increased flow.

Similar to a PDA complicated by pulmonary vascular disease.^[3]^[4]
Left ventricular overload regresses by adolescence and the heart size may revert to normal.
The apex may be tilted upward reflecting right ventricular hypertrophy.
The pulmonary trunk and its branches are markedly dilated and may show central calcification, but in the outer third there is an abrupt decrease in vascularity.
