ABSTRACT
We report a pulmonary artery (PA) aneurysm associated with severe aortic stenosis and an aortic root dilatation occurring in a 59-year-old woman who presented with dyspnoea and chest pain. PA aneurysms are rare, and there are no definitive guidelines on its management. There are contentious opinions on whether such aneurysms should be managed conservatively or surgically. Our patient had associated aortic stenosis and underwent a successful aortic valve replacement and PA aneurysm repair. This case illustrates that concomitant PA repair with other cardiothoracic surgery can be performed safely, even in patients with moderate surgical risks. We also discuss the natural history, prognosis and management of PA aneurysms.
