Abstract:
Pulmonary artery aneurysms are rare. We describe 2 adult patients with pulmonary artery aneurysm with normal pulmonary pressure associated with bicuspid pulmonary valve and atrial septal defect. One patient presented with moderate pulmonary valve stenosis and was treated with open surgery; the other patient had a small atrial septal defect and mild pulmonary valve insufficiency and is periodically still being evaluated. Hemodynamic alterations associated with a pulmonary artery aneurysm are described; the influence of additional volume overload and intrinsic wall abnormalities in pulmonary valvular lesions as potential triggers for the development of these aneurysms are analyzed and therapeutic strategies are discussed.
