Abstract

Primary tumors of the heart are rare in infancy and childhood and are most often benign. The most common cardiac tumors are rhabdomyoma, fibroma, and myxoma. Rhabdomyomas occur as single or usually multiple nodules embedded in chamber walls. They may remain clinically unimportant or even regress but also cause mechanical obstruction, heart failure, or arrhythmias. It is generally accepted that 50% of cardiac rhabdomyoma are associated with tuberous sclerosis. We experienced two cases of fetal cardiac tumor which were detected by prenatal ultra sound. One case was multiple cardiac rhabdomyomas diagnosed in 37 weeks of gestation. After birth, brain MRI was performed and tuberous sclerosis was diagnosed. The other case was 1.2 cm sized single hyperechoic mass in the left ventricle. Postnatal echocardiography confirmed the prenatal diagnosis.
