Bloqueio atrioventricular de alto grau induzido pela cirurgia cardíaca: estudo de critérios de reversibilidade

Abstract

O bloqueio atrioventricular de alto grau (BAVG) pode se manifestar, em pequena incidência (2,1%), no pós-operatório de cirurgia cardíaca e ter caráter temporário ou permanente. Na ausência de critérios de reversibilidade, o tempo de permanência superior a 15 dias é indicativo de marcapasso cardíaco permanente (MPCP). Casos isolados poderão reverter após este período. Num estudo de 4 casos de bloqueio em 300 intervenções cardíacas, os autores confirmam que a freqüência cardíaca e a comparação das características do QRS nos períodos antes, durante e após o bloqueio não constituem critérios de reversibilidade; o eletrograma do feixe de His é dispensável na adoção da conduta; o período de 15 dias é adequado para a indicação do MPCP e o tempo corrigido de recuperação do marcapasso é indicativo de atividade juncional ou idioventricular incerta e deve ser estudado como critério de reversibilidade.High degree atrioventricular (AV) block is manifested in low incidence (2,1%) during postoperative heart surgery and could be transient or permanent. In the absence of block reversibility criterions. permanent pacemaker (PPM) implantation is recommended when AV block is persistent longer than 15 days. In isolated cases the block could be reversible after this period. Av block occurred in 4 of 300 patients who underwent cardiac surgery. We reviewed their records and confirmed that neither the heart rate nor compared QRS characteristics in the periods before, during or after block, is usefully to predict block reversibility. The intracardiac electrophysiologic study is unnecessary to indication of PPM. Corrected pacemaker recovery time greater than 2 seconds indicates junctional or idioventricular activity uncertain and should be investigated as block reversibility criterion.
