[Surgical treatment of aneurysm of the membranous ventricular septum: report of 27 cases].

Twenty-seven patients aged 4 to 26 years with aneurysm of the membranous ventricular septum were operated on in Shanghai Chest Hospital, from August 1985 to April 1987. Of the patients, 22 were diagnosed by left ventriculography, and were found to be associated with other cardiac defects such as VSD, ASD. All the patients had an uneventful early postoperative course and excellent late results. It is emphasized that a thorough recognition of the lesion and complete repair of the malformation are important in the avoidance of residual shunt and recurrent defects.
