Abstract 20040: Risk Assessment in Pregnant Women With Congenital Heart Disease

Introduction: As more women with congenital heart disease (CHD) survive into their childbearing years, clinicians are faced with assessing pregnancy risk. Published risk stratification schemes have shown variable accuracy in predicting adverse cardiac outcomes in pregnancy for women with CHD. Hypothesis: The modified World Health Organization (WHO) criteria are superior to the CARPREG and ZAHARA risk scores in predicting pregnancy outcomes in CHD. Methods: This is a retrospective, single center study examining women ≥ 18 years with CHD who delivered between 1998 and 2014. CARPREG and ZAHARA risk scores and modified WHO criteria were applied to each subject. Cardiac events (i.e. at least one of the following: arrhythmia, heart failure or pulmonary edema, thromboembolic complications, transient ischemic attack, stroke, endocarditis, myocardial infarction, cardiac arrest, cardiac death) were assessed up to six months post-partum. Logistic regression analyses were performed and the area under the receiver ope...
