Abstract Newborn male with symptomatic bradycardia initially diagnosed with complete atrioventricular block. Isoproterenol drip was initiated, and the patient was scheduled for pacemaker implantation. During the hospital course, repeat electrocardiogram and Holter monitor revealed evidence of near continuous blocked atrial bigeminy with occasional aberrantly conducted premature atrial contractions. Flecainide was started, resulting in normal sinus rhythm, and the pacemaker implantation was cancelled.

Congenital complete heart block is defined as a complete atrioventricular block occurring prenatally, at birth, or within the first month of life. Congenital complete heart block has a high mortality rate, and in infants with normal heart morphology, it is often associated with maternal connective tissue disease. In these latter cases, neonatal congenital complete heart block is usually irreversible. We present a rare case of a female neonate who had bradycardia noted at a gestational age of 37 weeks. Her mother had no autoimmune disease history. She had no structural heart disease, and the serology surveys for autoantibodies including SSA/Ro and SSB/La were all negative. Without intervention or medication, her congenital complete heart block completely recovered to a normal sinus rhythm within 5 days. The cause of the transient congenital complete heart block was unknown in this case.

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.

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.

Abstract Atrioventricular block in children is not common but is a life-threatening disease. As no spontaneous regression of conductive disruption was reported, those sustaining idiopathic atrioventricular blocks are difficult to manage and often require pacemaker implantation. In this study, we presented the first case of a child who surprisingly recovered from idiopathic complete atrioventricular block without intervention 4 years after initial presentation.

AbstractPermanent pacemaker implantation in low birthweight (LBW) babies with congenital complete heart block is extremely challenging due to a paucity of appropriate pulse generator placement pocket sites. The development of infection following an implantation procedure can pose a life-threatening risk to the patients. With more patients in the younger group receiving these devices than ever before and the rate of infection increasing rapidly, a closer look at the burden of infection and its impact on outcome of these patients is warranted. We report mucormycosis infection at the abdominal pacemaker pocket site of an infant requiring pacemaker explantation and re-insertion into the intrapleural space.

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.

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.
