Relationship between hospital procedure volume and complications following congenital cardiac catheterization: A report from the IMproving Pediatric and Adult Congenital Treatment (IMPACT) registry

Although the risk of MAE after cardiac catheterization in patients with CHD is low at all hospitals, it is higher among hospitals with fewer than 150 cases annually. These results support the notion that centers meeting this threshold volume for congenital cardiac catheterizations may achieve improved patient outcomes.
