Evans and colleagues reported aortic aneurysms occurring in 15% of patients at a median of 6 years after the initial diagnosis of GCA. Two thirds were thoracic aortic aneurysms, with the majority located in the ascending aorta. Almost 33% of patients developed symptomatic aortic regurgitation. Approximately 50% of patients with thoracic aortic aneurysms died suddenly from aortic dissection.
