Reliable diagnosis of congenital heart defects and arrhythmias in utero has been possible since the introduction of fetal echocardiography. The nation-wide prenatal ultrasound screening program in the Czech Republic enabled detection of cardiac abnormities in 1/3 of patients born with any congenital heart disease and up to 83 % of those with critical forms. Prenatal frequency of individual heart anomalies significantly differed from the postnatal frequency. Fetal isolated complete atrioventricular block and supraventricular tachycardia may lead to heart failure and are important causes of fetal mortality. The regression of heart failure was achieved by a conversion to the sinus rhythm in the supraventricular tachycardia and by increase of ventricular rate in the complete atrioventricular block.

Aims: To describe a case of neonatal lupus and complete atrioventricular block in Mexico. Presentation of case: A 38 years old pregnant patient at  28 + 6 weeks of gestational age, diagnosed with systemic lupus erythematosus six years ago, under treatment with hydroxychloroquine and prednisone, this was suspended eight months prior to pregnancy; and resumed at week 20 of gestational age. The ultrasound scan showed alive fetus, female, polyhydramnios and bradycardia. Fetal echocardiography confirmed complete atrioventricular block, without organic and structural alterations at the cardiac level. Furthermore, the immunological panel reports, positive anti-Ro antibodies. At week 33 of gestational age, the patient was admitted to the obstetric emergency room, through colic type pain and 4 cm dilation of the cervix. Alive newborn got vaginally with a weight of 1,990 g, a height of 43 cm and APGAR 8-9. Echocardiography confirmed congenital complete third degree atrioventricular block; without structural abnormalities. Discussion: Patients with systemic lupus erythematosus, are more likely to have complications during pregnancy. Neonatal lupus is a rare disorder with an incidence of 1:10,000 - 1:20,000 newborns. This is caused by the transplacental passage of maternal autoantibodies anti-SSA / Ro and/or anti-SSB / La. Besides Atrioventricular block is a complication of neonatal lupus, occurring in approximately 2% of newborns of mothers who have SSA or SSB antibodies. The most interesting finding is that 20% fetal mortality has been for this cause. Conclusion: The described case is important for its rarity. Besides, the imaging findings and immunological panel emphasized the relevance about complete and adequate evaluation of the fetus, in the context of a mother with systemic lupus erythematosus.

AbstractSymptomatic, circulatory collapse occurred in an unvaccinated child with repaired congenital heart and a backup pacemaker during an Influenza B viral infection with complete atrioventricular block and pacemaker non-capture. Ventricular arrhythmias occurred during her collapse. Atrioventricular conduction recovered within 24 hours. Influenza-associated cardiac inflammation can adversely affect patients with repaired CHD. Proactive immunisation is strongly recommended.

Objective.To study anti-Ro/La-negative congenital heart block (CHB).Methods.Forty-five fetuses with CHB were evaluated by analysis of anti-Ro/La antibodies using sensitive laboratory methods.Results.There were 9 cases of anti-Ro/La-negative CHB; 3 died (33.3%). Only 3 (33.3%) were complete in utero and 5 (55.5%) were unstable. No specific etiology was diagnosed. Six infants (66.6%) were given pacemakers. There were 36 cases of anti-Ro/La-positive CHB. All except 2 infants (94.4%) had complete atrioventricular block in utero. Ten died (27.8%), one (2.7%) developed severe dilated cardiomyopathy, and 26 (72.2%) were given pacemakers.Conclusion.Nine of the 45 consecutive CHB cases (20%) were anti-Ro/La-negative with no known cause. They were less stable and complete than the anti-Ro/La positive cases.

Permanent pacemaker implantation and medical therapy due to complete atrioventricular block and comorbid cardiac pathology are considered at an example of clinical case. Permanent pacemaker solved the problem of AV-block, however, drug therapy due to arterial hypertension, heart failure and dyslipidemia is not canceled and requires modification.
