Abstract
We reviewed patients with chromosome 22q11.2 deletion syndrome. We analyzed cardiovascular findings in patients with confirmed chromosome 22q11.2 deletion syndrome live-born in Nevada between March 2007 and September 2020. We identified 60 patients. Of the 60 patients, 32 (53%) were female. Of the 60, 48 (80%) had a conotruncal abnormality (including isolated vascular rings): 23 of 32 (72%) for females versus 25 of 28 (89%) for males, P = .41. However, 11 (34%) of 32 females had a right aortic arch; whereas, 21 (75%) of 28 males had a right aortic arch, P = .007. In conclusion, in our patient cohort, we found conotruncal malformations were common. However, we noted males were statistically more likely to have a right aortic arch than females. To the best of our knowledge, this male-female aortic arch laterality difference in patients with chromosome 22q11.2 deletion syndrome has not been previously noted.
