[Diagnosis of cardiac rhabdomyoma in the first trimester of pregnancy]. / Diagnóstico de un rabdomioma intracardiaco en el primer trimestre de la gestación.

BACKGROUND: Rhabdomyoma is the most common cardiac tumor detected during fetal life and childhood; despite of this, its incidence is very low. CLINICAL CASE: cardiac rhabdomyoma diagnosed at first trimester ultrasound. CONCLUSION: Early diagnosis is important for performing further studies to detect the possible presence of associated anomalies, including TS (tuberous sclerosis). Prognosis is conditioned by number, size and location. In our case, the presence of early hypoplastic right ventricle and pulmonar and tricuspid atresia (probably because of tumor size) conditioned a very bad prognosis, so the patient decided termination of pregnancy.
