Impact of Lesion Severity in Fetal Cardiac Counseling.

Approximately 1% of all live births in the USA are affected by congenital heart disease (CHD), the leading cause of congenital defect-related illness and infant death. Although technological innovations have improved CHD diagnosis in utero, variation among fetal cardiac counseling practices persists. Our study aims to evaluate physician counseling content based on cardiac defect complexity. We conducted an anonymous survey of providers who perform fetal cardiac counseling. Participants stated their counseling practices for 21 CHD lesions, choosing from postnatal surgical intervention, termination of pregnancy, and/or postnatal palliative comfort care. CHD lesions were divided by severity into three groups. Chi-square tests were performed to assess whether counseling content varied based on provider response to the statement "some life is always better than no life at all." There were 138 respondents, with postnatal surgical intervention counseling frequency consistent among all lesions. Inclusion of termination and palliative/comfort care in counseling increased in frequency as disease severity increased, with the former being counseled more frequently. For tetralogy of Fallot (p = 0.02), interrupted aortic arch (p = 0.03), hypoplastic left heart syndrome (p = 0.03), and pulmonary atresia with intact ventricular septum (p = 0.03), those providers who disagreed with the statement that "some life is always better than no life at all" were more likely to counsel termination of pregnancy and/or palliative care compared to their counterparts. Our study found that the interventions and options included in fetal cardiac counseling vary based on complexity. Moreover, physicians' personal beliefs tended to influence counseling practices in some moderate or severe defects.
