Abstract:
OBJECTIVETo evaluate the perinatal management and outcome of different types of fetal arrhythmia.
METHODSA retrospective analysis was conducted among the fetuses with arrhythmia identified by M-mode and pulsed Doppler echocardiography in a single institution between October 2003 and December 2010.
RESULTSA total of 130 fetuses were found to have fetal arrhythmia. The most common arrhythmia during pregnancy was extrasystole (n=59), followed by bradycardia (n=23), tachycardia (n=16), atrial flutter (AF, n=3), atrioventricular block (AVB, n=12) and other arrhythmia (n=17). The overall incidence of cardiac anomalies (commonly fetal bradycardia) was 9.2% in these cases. The prognosis of arrhythmia differed significantly between cases of different classifications. The type of fetal arrhythmia (P=0.024), presence of congenital heart defect (CHD, P=0.000) and fetal hydrops (P=0.008) were significant risk factors associated with termination of pregnancy.
CONCLUSIONFetal arrhythmias without CHD or hydrops under close monitoring often have good clinical outcome, while fetal bradycardia is associated with a high mortality rate. CHD and the presence of fetal hydrops are significant risk factors for pregnancy termination.
