Successful replacement of the interventricular septum following excision of a large intramural fibroma.

Successful removal of tumours of the heart involving the ventricular septum is uncommon. Review shows that of thirty endocardial fibromata reported, only six involved the septum. We wish to report another case, in which a large endocardial fibroma had replaced the ventricula septum and was removed, necessitating the reconstruction of this septum.
