[Peripartum idiopathic myocardiopathy: prospective echocardiographic study].
Still frequent in Africa, the idiopathic peripartum cardiomyopathy (PPC) is the subject of only few prospective studies. The aim of this prospective work was to assess the echocardiographic abnormalities of the PPC and to determine on 26 patients the evolution and the prognostic factors of this disease. Six women had mild to moderate pericardial effusion. The abnormalities of the wall motion, constantly found, were diffuse in 20 cases (77.1%) and localized or prevalent on the interventricular septum or the left ventricular posterior wall in the other cases. The cardiac chambers were dilated in 24 cases (92.3%). Left ventricular hypertrophy was noted among 16 patients (61.5%); it was eccentric in 15 cases. The left ventricular systolic dysfunction was constant. The other abnormalities were: the abnormal left ventricular relaxation (one case), low mitral and aortic flow (12 cases), the mitral (21 cases) and tricuspid regurgitation (five cases). One noted a septal hypertrophy and an isolated dilatation of the right ventricle. The mean follow-up was 7.3 +/- 1 month (1-18 months). Two patients died at the 4th and 8th month. Among the 24 survivors, 11 had normalized were: the gestity (p = 0.01), the parity (p = 0.01), the cardiothoracic ratio (p = 0.04), the left ventricular volumes (p = 0.02), and the parameters of left ventricular function. The echocardiography of patients with PPC usually shows a pattern of dilated and hypokinetic cardiomyopathy, but many variations are possible. Most of the patients keep echocardiographic abnormalities after mean term follow-up.
