Partial replacement of the left ventricular wall for a large intramural fibroma.

A case of successful operative treatment of an intramural fibroma of the left ventricular posterior wall is presented. Symptomatology, diagnosis, and a surgical procedure based on ventricular replacement using a doubled Dacron patch, fixed in "sandwich" technique, are discussed. It is possible to resect and replace large parts of the ventricular wall because of the well-developed compensatory capacity of the remaining unaffected myocardium in children.
