These manifestations include transient fetal first-degree heart block prolongation of corrected QT QTc interval sinus bradycardia late-onset cardiomyopathy endocardial fibroelastosis and cardiac malformations. Anti-SSA Ro antibodies are not considered pathogenic to the adult heart but a prolongation of the QTc interval has recently been reported in adult patients and is still a matter of debate. Treatment of CHB is not well established and needs to be assessed carefully. The risks and benefits of prenatal fluorinated steroids are discussed. Introduction Anti-SSA Ro antibodies have long been associated with an increased risk of fetal congenital heart block CHB . Apart from complete and incomplete CHB new cardiac manifestations related to anti-SSA Ro antibodies have been reported in children born to mothers bearing these antibodies. These manifestations include transient fetal first-degree heart block 1 prolongation of corrected QT QTc interval 2 3 sinus .
