Taggart et al reported the CRISA (Catheterization RISk in Adult patients) score for predicting the risk of cardiac catheterization for an adult with congenital heart disease. The authors are from the Mayo Clinic, Wayne State University, Children's Hospital of Michigan, Arnold Palmer Hospital for Children in Orlando, Ann & Robert H. Lurie Children's Hospital Chicago and the University of Georgia.
Patient selection: adult with congenital heart disease
Parameters:
(1) age in years
(2) systemic illness or organ failure (comorbidity)
(3) ASA score
(4) physiologic score category (based on oxygen saturation, pulmonary vascular resistance index, right ventricular systolic pressure, need for transfusion, atrioventricular valve regurgitation, dynamic subpulmonary obstruction)
(5) precatheterization diagnosis category (3 categories of 147 diagnoses)
(6) procedure risk category (3 categories of 75 procedures)
(7) procedure type (diagnostic, interventional, hybrid)
(8) sedation or anesthesia

Interpretation:
• minimum score: 0
• maximum score: 22
• The higher the score the greater the risk.
