“[P]rovide compelling evidence that AHI and CSAH are clinically useful measures for risk stratification in patients with root and ascending aortic aneurysms... but before such tools can be adopted into routine clinical practice, further validation is required.”
Evaluates improved risk stratification for surgical intervention in ascending aortic dilation patients, suggesting earlier surgery benefits.
BACKGROUND: Indexing ascending aortic dimensions to height, rather than absolute diameters, may better identify at-risk ascending aortopathy (AA) patients who could benefit from earlier surgery. OBJECTIVES: This study evaluated whether height-indexed aortic dimensions improve long-term risk stratification in AA patients who do not meet current surgical guidelines. METHODS: /m) index were calculated. The primary outcome was mortality. RESULTS: /m were associated with higher long-term mortality (both P < 0.05). CONCLUSIONS: Indexing AA dimensions to height better identifies high-risk AA patients, particularly women, who fall below surgical criteria. Further studies are needed to determine if this cohort may benefit from earlier intervention at lower size thresholds.
