Seven children with primary cardiac tumors are discussed. The diagnosis was achieved by cardiac catheterization in all seven patients. In four patients, surgical excision was undertaken with one long-term good result. One of the other three surgical patients died of acute heart failure at the discontinuation of cardiopulmonary bypass. One of the other two surgical patients died suddenly late postoperatively, presumably from arrhythmia. The other, affected by fibrosarcoma, also died suddenly while undergoing chemotherapy. The histologic findings on the tumor masses were available in six patients. There were three rhabdomyomas, one fibrosarcoma, one fibroma and one hamartomatous mass. In one patient with tuberous sclerosis, a presumptive diagnosis of rhabdomyoma was made clinically on the basis of multiple masses infiltrating the left ventricle. Two-dimensional echocardiography is the best noninvasive tool to determine the extent and location of the tumor and suitability for surgery. When surgery is indicated, cardiac catheterization for pressure data is also required. Surgery is recommended in symptomatic solitary lesions that most likely are fibromas and have an overall good surgical outcome.
