Primary cardiac tumors in children.

Case histories of five children with primary cardiac tumors are presented. The clinical and pathological features of the most frequent cardiac neoplasms in childhood are also reviewed. Cardiac tumors should be suspected in any child with unexplained heart murmurs, congestive heart failure, or cardiac arrhythmias. Echocardiography, cardiac catheterization, and biplane cineangiograms provide diagnostic confirmation. Prompt surgical resection is indicated in all symptomatic patients and in those with significant inflow and outflow tumor-related obstruction. Complete resection is not possible in many patients with cardiac rhabdomyoma or lipoma but removal of the obstructive portion of the tumor frequently provides long-term symptomatic relief.
