Remission of congenital complete heart block without anti-Ro/La antibodies: A case report

Anti-Ro/La negative congenital heart block (CHB) is uncommon.We report one such case of CHB, with no associated structural heart disease or maternal autoantibodies.The heart block reverted to 5-HTP sinus rhythm spontaneously at two weeks of age, and the patient remains in Microphone Data Cable sinus rhythm at a one year followup.Whether patients with antibody negative complete heart block have a different clinical course is conjectural.
