Imaging and Surveillance of Chronic Aortic Dissection: A Scientific Statement From the American Heart Association

This newly released AHA scientific statement offers a comprehensive review of the latest imaging and measurement techniques for patients with chronic aortic dissection and clarifies the need for standardized measurements and reporting for lifelong surveillance. It is divided into seven parts: epidemiology and anatomic spectrum; pathophysiology; managment of chronic aortic dissection; imaging technique; measurement principles; surveillance imaging; and risk stratification and new developments. The emerging role of imaging and computer simulations is examined to predict aortic false lumen degeneration, remodeling, and biomechanical failure from morphological and hemodynamic features.  The writing group also identifies critical knowledge gaps and research needs that may serve as an impetus for additional research and development.
