Chest X Ray
Small VSD
- Normal heart size and pulmonary vascularity.
Medium-sized defect (or moderate left-to-right shunt)
- Slight cardiomegaly. It can cause signs of left ventricular dilatation.
- Increased pulmonary vascular markings in both the central and the peripheral portions of the lung field.
Large VSD, Eisenmenger syndrome
- Left ventricular hypertrophy may regress in adults. Reversal of shunts can cause right ventricular hypertrophy that in turn causes the apex to tilt upward.
- Dilated proximal pulmonary vessels, pruned peripheral vessels (pulmonary hypertension). Also, calcification of the pulmonary artery may be seen.
