Abstract

Congenital complete atrioventricular block is an uncommon congenital lesion, occuring in about 1 of 20,000 newborns. Most of complete atrioventricular block without additional structural heart defects were born to mothers who had either manifested connective tissue disease or tested positive for anti-Ro (SS-A) antibodies. Previously, this diagnosis was usually made after birth. Because fetal arrhythmias can now be evaluated prenatally by two-dimensional and M-mode echocardiographic and Doppler ultrasound techniques, complete atrioventricular block is more frequently identified during the fetal period. The natural history and in utero management of congenital complete atrioventricular block is not well documented. We have experienced a case of congenital complete atrioventricular block without associated anomaly followed by successful implantation of cardiac pacemaker at the 7th day of life and presented this case with a brief review of the literatures.
