Abstract
It is enunciated that the Lutembacher syndrome can be approved of not only the atrial septal defect associated with the mitral stenosis but the mitral stenosis with secondary occurred or enlarged interatrial communication due to the left atrial hypertension. Moreover, the mechanism of the continuous murmurs occasionally heard at the lower sternal border is discussed from the present case and cases collected from the literatures. Successful surgical treatment of a patient with the Lutembacher syndrome in the above-mentioned concept is presented.
