[Conduction disorders in chronic parietal endocarditis or endomyocardial fibrosis. 170 cases at the Cardiology Institute of Abidjan].
The authors have conducted research on conduction disturbances in the endomyocardial fibrosis, synonymous with chronic parietal endocarditis, about 170 cases at the Institute of Cardiology in Abidjan, from January 1977 to June 1991. The anatomical and/or angiographic examination have permitted to describe 64 cases of right fibrosis, 24 cases of left fibrosis and 82 cases of bilateral fibrosis. Conduction anomalies have been observed among 42.9% of the patients. Among 92 anomalies recorded, the most frequent has been the first degree heart block (43.5%) and the incomplete right bundle branch block (30.4%). The old age of the patients and the right localization were the factors associated with conduction disturbances in endomyocardial fibrosis (difference not significant). Yet, fibrosis surgery, especially the decortication of the fibrous endocardium of the right ventricle, have generated one or many conduction anomalies among most of our operated patients. The right branch of the fasciculus of the His has been the most injured by the fragmented techniques of METRAS who had, therefore, the merit to have minimized the incidence of the complete post-operative heart blocks still high in European and Brazilian series. In term of prognosis, no conduction disturbance has directly caused a patient's death, even if those anomalies cannot be totally ruled out in the 16 cases of sudden death.
