Removal of a giant cardiac fibroma from a 4-year-old child

Abstract

In an 8-month-old infant presenting with a systolic heart murmur, a cardiac tumor was diagnosed by means of 2-dimensional echocardiography, cardiac catheterization, and magnetic resonance imaging. In the following years, the child developed ventricular arrhythmias, which were controlled with antiarrhythmic drugs. The operation was undertaken when the boy was 4 years and 3 months of age. A tumor of the interventricular septum measuring 45 x 13 x 25 mm was resected in toto. The defect in the ventricular septum was closed with a Dacron patch. The postoperative course was uneventful. Histologic examination classified the tumor as a fibroma.
