Dilated cardiomyopathy in isolated congenital complete atrioventricular block: early and long-term risk in children

Abstract: Isolated CCAVB is associated with a long-term risk for the development of DCM. Risk factors may be SSA/SSB antibodies, increased heart size at initial evaluation and the absence of pacemaker-associated improvement.

“…At present, more than 94% of children with CCAVB are paced before they reach the age of 15 years (Villain et al, 2006). Another important prognostic issue in children with autoimmune-associated CCAVB is the development of dilated cardiomyopathy (Moak et al, 2001;Udink ten Cate et al, 2001). We and others have demonstrated that as many as 6 -11 % of paced children with autoimmuneassociated CCAVB develop dilated cardiomyopathy during a follow-up period of 10 ± 7 years (Moak et al, 2001;Udink ten Cate et al, 2001;Kim et al, 2007).…”

“…A presença destes autoanticorpos vem sendo reportada em até 95% das mães, quando o diagnóstico do bloqueio é feito na fase intrauterina ou no período neonatal 5,10 . A raridade do bloqueio AV congênito e a multiplicidade de formas de apresentação clínica dessa afecção podem ser a justificativa para o diagnóstico ter sido tardio em parte dos indivíduos avaliados [1][2][3]7,8 . Pode-se verificar, na análise retrospectiva das informações, que a doença foi detectada antes do nascimento ou no período neonatal em apenas 40% dos casos, sendo que em 16% deles o diagnóstico somente foi feito na adolescência.…”

“…Acredita-se que o desenvolvimento de miocardiopatia tardia possa ser secundário à miocardite autoimune intrauterina ou por sua reativação pós-natal 2,30 . Outras causas, todavia, também têm sido citadas como responsáveis pelo desenvolvimento de miocardiopatia dilatada nestes pacientes, em especial a miocardite viral e os efeitos deletérios da estimulação artificial crônica do ventrículo direito (VD) 29,[31][32][33][34] .…”
