Congenital cardiac fibroma associated with fetal arrhythmia.

A congenital cardiac fibroma presented itself, antenatally by bursts of extrasystoles which were detected by the cardiotocograph during labor. Congenital cardiac tumors are extremely rare. The symptomatology of such tumors consists mainly of hemodynamic disturbances and various arrhythmias. Most of the reported cases were diagnosed in neonates or infants, usually in autopsies, none were diagnosed in utero. It seems logical to assume that some of the arrhythmias may have been present but not diagnosed antepartum. To the best of our knowledge the association of congenital cardiac tumor and fetal arrhythmia (FA) has not been reported yet.
