Abstract A young child presented with hepatomegaly, ascites, and bradycardia in the setting of coronavirus disease-2019. Permanent complete atrioventricular block and severe right heart failure were diagnosed. He was treated with surgical epicardial pacemaker implantation. This report is the first description of coronavirus disease-2019–induced permanent complete atrioventricular block in a child.

At 32 weeks, a fetus was found to be hydropic with congenitally complete heart block in an asymptomatic mother who was positive to anti-Ro antibodies. Maternal therapy with oral salbutamol was successful in prolonging gestation for a period of 3 weeks so that preterm delivery was delayed until the 35th week of gestation. Following treatment with inotropes and diuretics, a permanent transvenous pacemaker was implanted at 8 weeks of age. The child is now thriving at 20 months of age.

Complete Atrioventricular

A fetal autoimmune-mediated atrioventricular block is a passively acquired autoimmune disease in which maternal autoantibodies enter the fetal circulation via the placenta and subsequently cause inflammation and fibrosis of the atrioventricular node. Once fetal autoimmune-mediated atrioventricular block occurs, it only takes a short time to progress from first-degree atrioventricular block to complete atrioventricular block, meaning that the damage is often irreversible. Autoimmune—associated AVB, a rare but life—threatening disorder, occurs in 2–5% of pregnancies with positive anti—Ro/SSA (the most common one) and La/SSB antibodies. The perinatal mortality of neonates with AVB outlined in research is approximately 30%. Thus far, for autoimmune-associated AVB fetuses, currently used treatments include corticosteroids, hydroxychloroquine, intravenous immunoglobulin (IVIG), b—sympathomimetic agent, and even plasma exchange. Currently, approaches for preventing the progression and recurrence of a fetal atrioventricular block are still controversial. Here, we reported a baby of successful prevention from the fate of the fetal atrioventricular block by adopting prophylactic comprehensive prenatal therapy.

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.

SummaryWe report a 12-year-old boy with hypertrophic cardiomyopathy presenting with syncope. His electrocardiogram showed first-degree atrioventricular block, complete right bundle branch block, conduction delay in the anterior fascicle of the left bundle branch, and intermittent complete atrioventricular block. We detected hypertrophic cardiomyopathy in the mother. The relationship between the diseases is discussed, and interpreted in the light of previous descriptions.

Objective: Complete heart block is an extremely rare and serious complication in pregnancy. Pregnancy outcome in patients with atrioventricular conduction block are unknown, with only a limited number of case reports published. This paper is aimed to report our case and review the available background literature. Method: Case report. Case: A twenty‐nine years old primigravida in labor presented at 38 weeks of gestation with referral from the primary health center due to bradycardia and her previous history of cardiac problem. Patient has been diagnosed with total atrioventricular block since 2 years ago. Electrocardiography assessment showed the presence of complete heart block. She was then planned for an emergency Caesarean section and later a temporary transvenous pacemaker was implanted. Conclusion: Management of complete atrioventricular block in pregnancy requires a good team consisting of obstetrician, anesthesiologist and cardiologist. Keywords: atrioventricular, bradycardia, heart block, pacemaker, pregnancy

Objetivo: reportar un caso de bloqueo auriculoventricular completo congénito y realizar una revisión de la literatura del diagnóstico y tratamiento.Materiales y métodos: se reporta el caso de una gestante de 27 años quien consulta a un hospital general de alto nivel de complejidad, con un embarazo de 33 semanas, con feto único, con diagnóstico de bloqueo auriculoventricular completo y cardiomiopatía dilatada secundaria. Se inició manejo prenatal con betamimético con pobre respuesta, por lo cual fue necesario finalizar el embarazo. El recién nacido requiere implantación de marcapasos ventricular en el primer día de vida con excelentes resultados en el seguimiento a un año. Se realiza revisión de la literatura  publicada en las bases de datos: Medline vía PubMed, Lilacs y SciELO mediante los términos: “fetal complete atrioventricular block”, “congenital complete heart block”, con límites de año de 2000 a 2016, en español e inglés.Resultados: se obtuvieron 21 publicaciones; siete reportes de caso, diez revisiones de literatura, cuatro estudios de cohorte. El diagnóstico se basa en la ecocardiografía fetal para determinar el intervalo PR, la relación auriculoventricular y la detección de anomalías intracardiacas, entre las que se encuentran: regurgitación valvular, hiperecogenicidad miocárdica/valvular-fibroelastosis endocárdica, contracciones atriales prematuras y efusión pericárdica. Respecto al tratamiento prenatal, los medicamentos más utilizados son los corticoesteroides y los betamiméticos. El tratamiento de la bradiarritimia severa refractaria neonatal puede requerir la implantación de un marcapaso como manejo definitivo.Conclusión: el bloqueo AV congénito de tercer grado requiere diagnóstico temprano y tratamiento oportuno, ya que se acompaña de alta morbimortalidad perinatal. Se requieren estudios con mayor calidad metodológica que permitan avalar otras opciones y esquemas terapéuticos prometedores.

Complete Atrioventricular

Between 1989 and 2000, 21 fetuses were diagnosed with complete atrioventricular block. Seven women with fetal ventricular rates of less than 60 were given oral terbutaline, and 6 of these had an initial increase in the fetal ventricular rate. Four fetuses (57%) maintained an increased average rate of 60 beats per minute and survived. Two fetuses returned to rates below 55 and died. The final fetus, with hypertrophic cardiomyopathy, was unresponsive. Terbutaline, therefore, is initially effective in raising the fetal ventricular rate, but this effect may be transient.
