Echocardiographic diagnosis of a pulmonary artery aneurysm.

Aneurysm of the pulmonary artery is an uncommon anomaly which may be very difficult to diagnose without angiography. The present report demonstrates that the echocardiographic diagnosis of a pulmonary artery aneurysm is feasible. Correlation between chest X-ray, echocardiogram, cardiac catheterization, angiography and necropsy is presented. Several echocardiographic features of the pulmonic valve motion in pulmonary hypertension, not previously described, are discussed.
