Cardiac findings in routine fetal autopsies: More than it meets the eye? E. Rios * , C. Bartosch, C. Ramalho, J. Monterroso, O. Brandão * Centro Hospitalar S João, Pathology, Porto, Portugal Objective: Congenital heart disease (CHD) is the most common malformation in newborns. Our aim was to evaluate the spectrum of CHD in consecutively performed fetal autopsies and to correlate prenatal and postmortem diagnoses. Method: A retrospective study of 726 fetal autopsies was performed in a tertiary referral hospital. CHD was classified in seven categories: left ventricular outflow tract obstruction-LVOTO, right ventricular outflow tract obstruction-RVOTO, septal defects, connection anomalies, conotruncal anomalies, complex anomalies and others. Cardiac defects were also classified as isolated or associated with others anomalies.
