[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.

[Coronary disease with normal coronarography in the black Africans: epidemiological and clinical data in 31 cases. Role of abnormal hemoglobins].

The authors studied 31 cases of coronary artery disease with normal or minimally diseases coronary arteries in black Africans, 29.8% of 104 coronary patients undergoing coronary angiography in this series. These 31 cases comprised 16 cases of infarction, 10 cases of angina, 3 ventricular aneurysms and 2 cases of silent ischemia in diabetic patients. Twenty-five patients were men (80.6%). There were 6 women (19.3%) two of whom presented in the post-partum period. The average age of these patients was 45 years (males: 47.7 years; females: 41.8 years). The following risk factors were noted: smoking (60%), hypertension (25.8%), obesity (29%), diabetes (12.9%), serum cholesterol (average 2.15 g/l), serum triglycerides (average 1.25 g/l). The risk index per patient was 1.29. In comparison with coronary patients with angiographic coronary lesions (n = 73), the patients with normal angiography were significantly younger, comprised more females and had fewer risk factors (especially hypertension and diabetes), though this was not statistically significant. The prevalence of inaugural infarction was 81.2% in the cases of infarction with normal coronary arteries. These infarcts may be complicated by ventricular aneurysm formation. Spontaneous spasm was observed in 3 out of 31 patients (9.6%) at coronary angiography. A provocative test was performed in only 2 cases and 1 was positive. This deserves further study and may have therapeutic implications. The authors emphasise the high incidence of hemoglobin S or C traits (57.1%). These heterozygotic hemoglobinopathies could be a risk factor in these coronary patients with normal coronary angiography.

[Total anomalous pulmonary venous return into the coronary sinus. Apropos of 1 case with a difficult diagnosis and surgical success].

The case of an 8 year-old boy with total anomalous pulmonary venous return into the coronary sinus is reported. The coronary malformation comprised a considerable dilatation of the coronary sinus which made diagnosis very difficult even at open heart. The surgical success was obtained by resecting the interatrial septum and partitioning the atrium. The anatomical diagnosis of this condition and the malformations with which it could be confused are discussed: TAPVR into the right atrium, cor triatriatum. The two parts of the coronary sinus, confluence of the cardiac veins and the left horn of the sinus venosus, are described.
