[Chronic left parietal endocarditis. Clinical, paraclinical and peroperative study of 22 cases]

From 22 patients with left chronic parietal endocarditis (CPE), conducted an epidemiological, clinical, paraclinical and per-operative study. The CPE is frequently encountered in the Ivory Coast in Akan children living in forest areas in 81 p. cent of the cases. It causes a mitral insufficiency, of the which the essential mechanism is fibrosis of the sub-valvular apparatus. The clinical examination is that of a severe advanced mitral insufficiency. Cardiomegaly is the rule. In 31 p. cent of cases, the ECG shows a Qr in V1. The dip plateau on the apexocardiogram is never found and the protodiastolic endocardial resonance is inconstant on phonomechanical processor. The aspect in M of the interventricular septum, found in 72 p. cent of the cases on echo TM is of major importance when direct signs are missing on bidimensional sonograms. Angiocardiography remains the reference diagnostic examination. But only the surgical survey enables to demonstrate limited forms.
