Compared with indices that include weight, a simpler height-based ratio (avoiding weight assessment and BSA calculation) yields satisfactory results for evaluating the risk of complications among patients with TAAA. Turner syndrome (TS) is a relatively common chromosomal disorder affecting 1/2000 live-born girls. Both ASI and AHI were shown to be significant predictors of complications (p < 0.05). Indexing aortic valve area by body surface area increases the - PubMed Conclusions: Epub 2019 Mar 19. Those with aortic size index 2.5 cm/m 2 are at highest risk for aortic dissection. Demographics and clinical characteristics, LV dimensions, and aortic diameters, both absolute and relative to BSA, are presented as mean SD and were tested by unpaired t test to evaluate differences between genders. Principally, the Society wanted to ensure that reference intervals were derived from the most contemporaneous and prospectively acquired data; that reference intervals were derived from evidence that best applies to the British population; and finally that echo guidance and cut-offs reflect UK practice. Accurate measurements of the aortic annulus and root are important for guiding therapeutic decisions regarding the need for aortic surgery.
