Selective coronary angiography in pediatric patients

Selective coronary angiography (SCA) is an important diagnostic tool in pediatric cardiology; however, there are few reports on its feasibility and safety in young patients. We reviewed our experience with SCA from July 1, 1993 to December 31, 1997. There were 158 cardiac catheterizations that included SCA in patients whose ages ranged from 2 days to 46 years (median, 5.3 years). The most common indication was surveillance for coronary vasculopathy after heart transplantation. A retrograde approach was used in all patients through the femoral artery (n = 157) or umbilical artery (n = 1). Preformed coronary catheters were used and the Judkins left (JL) and Judkins right (JR) were the most common catheters, with the catheter curve size correlating with patient height (R-2 =.76 for JL, R-2 = .673 for JR). Complications during SCA included brief ST-T wave changes (11%), bradycardia (2.5%), and ventricular fibrillation (0.6%). Complications of vascular access were transient pulse loss (6%), hematoma (5%), and rebleeding (0.6%). Only one case of femoral artery occlusion was encountered on subsequent cath. In conclusion, complications of SCA were infrequent and serious complications were rare. SCA can be safely performed in pediatric patients at any age including neonates.
