title: [Diagnosis and treatment of cardiac rhabdomyomas].
abstract: A diagnosis of primary cardiac tumors was achieved by two-dimensional echocardiography in 3 patients. Two of them were female neonates, born of the 29th and 40th gestational week who had shown intrauterine arrhythmias. Subsequently, we were able to diagnose tuberous sclerosis in both. The third child, a 121/2 year old boy, with already diagnosed tuberous sclerosis, presented an electrocardiographical preexcitation syndrome. Because of the multiplicity of the tumors and the association with tuberous sclerosis we presumed that the tumors were rhabdomyomas. As it is known that rhabdomyomas show no, or only a minimal postnatal growth, we decided neither to perform a heart catheterization nor to treat them surgically unless the children show hemodynamical deterioration, although the tumors were huge in both neonates. The subsequent 14 months showed a clear regression in the size of the tumors. One of the neonates was successfully treated with amiodarone because of ventricular tachycardia. The second neonate didn't require any treatment. We conclude that: Surgical management is only necessary in patients presenting with cardiac insufficiency and/or arrhythmias that are resistant to conventional medical treatment. Primary cardiac tumors should be looked for in patients presenting with arrhythmias, even when occurring already during intrauterine life. Diagnostic measures in order to diagnose tuberous sclerosis in patients with cardiac tumors are necessary and vice versa.
