OTERO, Juan Carlos. Prenatal diagnosis of tumour of the foetal heart (rhabdomyoma). Rev Colomb Obstet Ginecol [online]. 2005, vol.56, n.2, pp.176-179. ISSN 0034-7434.

Primary heart tumours are rare. Overall incidence ranges from 0.002-0.250% in autopsy. Rhabdomyoma is the most common benign tumour (50-78%); it has 72% associated with tuberous sclerosis. This tumour tends to return in most cases. Typical symptoms are secondary to adverse effects caused by left ventricular geometry (cardiac wear and ejection). Hydrops foetalis and arrhythmia often lead to sudden death. Abnormal atrioventricular (AV) conduction is due to a tumour disrupting nodal or septal conduc­tion tissue. Gestational age has ranged from 22 to 36 weeks when diagnosis has been made. Prognosis is frequently associated with arrhythmia and tuberous sclerosis. Prenatal digitalis therapy and other medications have been tried in cases of foetuses suffering from heart failure or arrhythmia. The patient’s prior consent has been given here to report a case of ante-natal diagnosis of cardiac rhabdomyoma to teach the diagnosis and management of foetuses suffering from this rare pathology.
