Salvador, BA, BrasilFundação Gonçalo Moniz, Instituto de Pesquisas Gonçalo Moniz. Salvador, BA, BrasilUniversidade Federal da Bahia. Salvador, BA, BrasilSclero-atrophy, fibrosis, vascular ectasia, phlebosclerosis and mild non-specific chronic inflammatory changes were observed in variable location and proportion involving the atrioventricular conducting tissue o f the heart in five human cases o f chronic Chagas’ myocarditis associated with complete atrioventricular block. One case presented complete destruction o f the A- V conduction system. In three cases the lesions were disseminated all along the conducting tissue but did not cause anywhere a complete disruption in the continuity o f the system. The distal portion o f the bundle branches were the most damaged sector o f the system, exceptfor the fasciculi o f the posterior division o f the left bundle branch which were relatively preserved. One case exhibited bilateral sclero-atrophy o f the bundle branches as the main change; and another showed early and mild fibrocalcific damage o f the penetrating portion o f the His bundle. The A -V node appeared as the least involved part o f the conducting system in the cases studied. Demonstration o f the lesions in this series o f cases seems important because: a) it reveals that complete atrioventriculr block in chronic Chagas’ disease results from disseminated lesions and not from fo ca l disruptive change as has been commonly observed in cases o f other etiologies; b) it shows that chronic inflammation can produce at the end variable and widespread vascular, degenerative andfibrotic alterations within the conducting tissue o f the heart, which may lead to its total destruction.Chronic Chagas’ myocarditisAtrioventricular
