[Congenital diverticulum of the left ventricle (author's transl)].

A case of congenital diverticulum of the left ventricle associated with probable mitral and tricuspid prolapses is presented. The authors comment on the absence of symptomatology in patients affected with this disease and point out the electrocardiographic, radiologic, and phonomechanocardiographic data. The importance of the left ventriculography in the diagnosis and classification of this disease stands out, as does the value of echocardiography (mode-M) in the diagnosis of mitral and tricuspid valvular prolapses which were associated in the present case. The classifications given by various authors in connection with this anomaly are reviewed and lastly the appropriate therapeutic approach is discussed. There is a surgical possibility for young asymptomatic patients, taking into account the little experience we have at present on the natural history of this disease.
