Background: This study aimed to evaluate whether an ultra- sound-guided access technique can improve upon the land- mark-guided technique in achieving quicker vascular access in the femoral artery and vein during pediatric cardiac catheterization.
Methods: A random sample of patients greater than 60 days of age (Group 1) and under 60 days of age (Group 2) were chosen during a time period (before 2013) when access was obtained using only land- mark-guided techniques and during a time period (after 2013) when ultrasound-guidance was used. Data collected included age (years), height (cm), weight (kg), body surface area (m2), access site/s, sheath size, case times, time of rst sheath entry, time of nal sheath entry, and total time to obtain access (minutes).
Results: Data was collected on a total of 101 patients for Group 1 and 50 patients for Group 2 in each time period. Patients were matched in regards to height, weight, and body surface area between the two time periods.
Additionally, the reimbursement bene t over a 6 month period in 2014 was $30, 000.
Conclusion: Our ndings show that the use of an unltrasound-guided technique to access the femoral artery and vein signi cantly decreases the time to vascular access and has bene cial nancial implications.

undersurface of the distal aortic arch and supplied a tortuous Aorto- pulmonary collateral (APC) to the right lung. The left lung was sup- plied by one large APC. (Fig 1)
Patient underwent stenting of the ductus and came o prostaglandin and was discharged home. Hypocalcemia was noticed during inten- sive care stay. Chromosomal microarray revealed a deletion of 2.54 MB on chromosome 22q11.21 involving several genes including the TBX1 gene.
Discussion: As per our knowledge this is the rst case report which shows the association of persistence of 5th aortic arch with PA, VSD, MAPCA and TBX1 gene deletion. TBX1 gene deletion has been shown to cause dysfunction of the neural crest cell and anterior heart eld lead- ing to the various cardiovascular anomalies in 22q11 del syndromes.
