Adverse Event Rates in Congenital Cardiac Catheterization: A New Understanding of Risks

We sought to characterize the frequency, severity, and attributability of adverse events (AE) in congenital cardiac catheterization and identify patient and procedural characteristics associated with AE. Risk for any AE was associated with age < 1 year (odds ratio [OR] 2.3), interventional cases (OR 2.2), increasing procedure type risk group (OR 1, 2.0, 2.5), and indicator of hemodynamic vulnerability (OR 1.6), all p < 0.001. Each of these and...
