Association between the ascending aortic length and sporadic type A aortic dissection

The ascending aortic length (AAL) appears to be associated with type A aortic dissection (TAAD) and may complement the aortic diameter in morphologic risk assessment, but additional prospective studies with standardized measurements and body-size adjustment are required before clinical thresholds can be established. Observed AAL values associated with TAAD were lower in this Chinese cohort than in the Western population.
