CARDIAC FIBROMA - CLINICOPATHOLOGICAL CORRELATES AND SURGICAL-TREATMENT

The clinicopathologic findings of 23 patients with cardiac fibroma are presented. The mean patient age was 13 years, with a range of 1 day to 56 years. The presenting symptoms included heart failure, arrhythmias, sudden death, cyanosis, and chest pain. Some patients had no symptoms, and one patient had Gorlin's syndrome. Echocardiography and magnetic resonance imaging were very sensitive in diagnosis. Nineteen patients underwent tumor resection or biopsy, and four tumors were diagnosed at cardiac transplantation or autopsy on explanted hearts. In five surgical cases, complex operations were necessary, including pericardial or synthetic patches, valve replacement, or coronary artery grafting. Two operative deaths occurred in patients with surgical resections and four operative deaths in patients who at the time of the operation were deemed to have inoperable disease and only biopsy was performed. Ah deaths but one were in patients younger than 2 years of age. Four patients with subtotal resections did well after the operation. Dense collagen was more frequent in tumors in older patients. We conclude that fibromas are congenital tumors that are frequently discovered in adolescents and adults. Surgical treatment is generally successful, and imaging techniques are helpful in preoperative assessment.
