Positive maternal anti-SSA/SSB antibody–relatedfetal cardiac compromise includes atrioventricular block, sinus bradycardia, myocarditis, cardiomyopathy, and thickening of the endocardium or endocardial fibroelastosis (EFE). EFE may be secondary to intrauterine viral infections, congenital heart disease, or maternal antibodies (Lurie, 1988; Newbould et al., 1991). Maternal antibodyrelated–EFE is usually associated with congenital atrioventricular block (CAVB) (Costedoat–Chalumeauet al., 2003). We report the first prenatal diagnosis of maternal anti-SSA/SSB antibody–associated EFE limited to the right ventricle without atrioventricular block.
