[Early post-operative arrhythmias in endomyocardial fibrosis or chronic parietal endocarditis in 84 cases studied at the Cardiology Institute of Abidjan].

: The authors have studied rhythmic events happened during early post-operative period in 84 operated patients for endomyocardial fibrosis, synonym nowadays to chronic parietal endocarditis, in the Institute of Cardiology of Abidjan (Cote d'lvoire), from January 1977 to July 1991. The mean age has been 15.6 +/- 43 years old. Endocardectomy was left in 25 cases, right in 32 and at last bilateral in the 19 others. The surgical way has been a left and/or right atriotomy. Mitral and/ ortricuspide valvular surgery has been always realised. The absolute prevalence of patients having presented one or several arrhythmias, atrial tachycardia and premature ventricular beats. The favouring factors have been the period of exclusion of the aortic root from circulation and number of endomyocardectomy. Atrial fibrillation has been related to auricular volume. Most of nodal arrhythmias have appeared with surgery. Endomyocardial fibrosis surgery has been greatful in rhythmic plan in 16% of patients. Early post-operative arrhythmias have been responsible forone case of the death of the operated patients and they have been present in seven other cases of the death.
