Fetal supraventricular tachycardia (FSVT) is a cardiac arrhythmia that bears a high mortality rate. In the majority of cases no morphological anomalies are found and death is caused by congestive heart failure. This report presents two cases of FSVT in which cross sectional echocardiography revealed obstruction of the foramen ovale with dilatation of the right heart without structural cardiac anomalies. After birth sinus rhythm re‐established under digitalis medication in both cases. The association between premature obstruction of the foramen ovale and unexplained intrauterine death in the third trimester of gestation is suggested.
