title: [An adult case of left ventricular-right atrial communication with a false aneurysm of membranous septum].
abstract: A case of left ventricular-right atrial (LV-RA) communication associated with a false aneurysm of membranous septum is presented. The patient was a 51-year-old woman. Using a left ventriculography this case was diagnosed preoperatively as LV-RA communication. We found that the right atrium was directly communicated with the left ventricle through a fibrous membranous aneurysm adhering to the septal leaflet of the tricuspid valve. It was suggested that a false aneurysm, made by jet lesion from the left ventricle, perforated to the right atrium. So the current case was considered an acquired infravaluvular type LV-RA communication formed in the course of the natural closure of the membranous ventricular septal defect.
