Comparative StudyRacial and ethnic disparities in mortality following congenital heart surgery.
Our objective was to assess risk-adjusted racial and ethnic disparities in mortality following congenital heart surgery. We studied 8483 congenital heart surgical cases from the Kids' Inpatient Database 2000. Black sub-analysis was performed using predetermined regional categories. ⋯ After adjusting for gender, income, and region, Blacks (OR, 1.76; p = 0.002) and Hispanics (OR, 1.34; p = 0.05) had a higher death risk. Racial and ethnic disparities in risk-adjusted mortality following congenital heart disease exist for Blacks and Hispanics. These disparities are not due to insurance but are partially explained by gender and region.

Magnetic resonance imaging of a distorted left subclavian artery course: an important clue to an unusual type of double aortic arch.
The objective of this study was to determine if distortion of the left subclavian artery course distinguishes double aortic arch with atretic left dorsal aorta from right aortic arch with mirror image branching. We performed a retrospective case series at a tertiary care center. Twenty-six patients undergoing magnetic resonance imaging for suspicion of a vascular ring were identified, 6 of whom had an atretic left dorsal aorta confirmed by surgical inspection. ⋯ Surgical observation confirmed the presence of an atretic left dorsal aorta that resulted in tension on the left subclavian artery pulling it posteriorly and inferiorly and completing the vascular ring. Patients with right aortic arch mirror image branching demonstrated no such subclavian artery distortion, and these patients did not have clinical symptoms suggestive of a vascular ring. Our results demonstrate that left subclavian artery distortion due to traction by an atretic left arch is an important diagnostic finding in the evaluation 6 patients with suspected vascular rings.
