Left ventricular fibroma in two children

Abstract Primary cardiac tumors are rare in infancy and childhood. We describe the features of large intramural ventricular cardiac fibromas discovered in two children. In the first, a left ventricular apical tumor was discovered by means of echocardiography and left ventriculography in a symptomless 8-year-old boy. The intramural fibroma was successfully resected. In the other case, an 8-month-old female infant with severe congestive heart failure, sudden ventricular tachycardia and fibrillation occurred during left ventriculography. At necropsy a tumor was seen bulging in the anterior wall of the left ventricle and in the ventricular septum. Histology showed the tumor to be a fibroma.
