  • Title: Aortic surgery for ascending aortic aneurysms under 5.0 cm in diameter in the presence of bicuspid aortic valve.
    Author: Kallenbach K, Sundt TM, Marwick TH.
    Journal: JACC Cardiovasc Imaging; 2013 Dec; 6(12):1321-6. PubMed ID: 24332284.
    Abstract:
    Aneurysm of the ascending aorta may cause acute type A aortic dissection, and the primary aim of a prophylactic operation is avoidance of this life-threatening complication. Current guidelines recommend prophylactic replacement of the aneurysmal ascending aorta at a diameter of ≥5.5 cm. However, several reports have shown that nearly 50% of patients with an acute type A aortic dissection present with an aortic diameter <5.5 cm. It is controversial how to best respond to these observations. Because surgical advances have led to a reduction of early surgical mortality between 1% and 3%, many clinicians believe that surgery is warranted in smaller aortas. Given the frequency of a bicuspid aortic valve (BAV), such a strategy has health implications for this population.
