BackgroundCardiac catheterization for patients with congenital heart disease has shifted from diagnostic to predominantly interventional procedures because of advances in catheter-based technologies. Children undergoing therapeutic catheterization may be at higher risk of adverse events, and the purpose of our study was to determine the incidence of cardiac arrest (CA) in patients with congenital heart disease undergoing cardiac catheterization at a large pediatric tertiary referral center.MethodsAll CAs from January 2004 through December 2009 occurring in the cardiac catheterization laboratory were reviewed. A CA was defined as an event in which cessation of circulation required chest compressions. Procedure, patient, practitioner, and system-related factors were examined.ResultsOver the study period, during 7289 catheterization procedures, 70 procedures were associated with a CA (0.96 [99% confidence interval, 0.7-1.3] per 100 procedures); 48 events (69%) were successfully resuscitated to a perfusing rhythm, 18 events (26%) resulted in need for extracorporeal membrane oxygenation, and 4 events (6%) resulted in unsuccessful resuscitation. Sudden onset of cardiac arrhythmia led to CA during 38 events (54%). The duration of resuscitation after CA was ≤11 minutes in 71%. Occurrence of CA was associated with interventional procedures (P < 0.001) and younger age (P < 0.001). A change in systems for scheduling and communication of cases was associated with a significant reduction in the incidence of CA (1.5% vs 0.7%; P = 0.002).ConclusionsThe incidence of CA in children undergoing cardiac catheterization is high compared with pediatric noncardiac surgery. Procedural and system factors were associated with occurrence of CA in this cohort. These issues highlight the need for close communication, anticipation, and preparation.
