Longitudinal functional assessment of atrial M-mode in dextro- transposition of the great arteries fetus may help to predict the necessity for urgent neonatal Rashkind procedure.

ABSTRACT

Six fetal echocardiographic examinations were analyzed and presented with special emphasis on atrial M-mode in one case of fetal isolated dextro- transposition of the great arteries. The only significant changes were seen based on analysis of the new index of foramen ovale (FO) flap movement. Emergency Rashkind procedure on the first day of postnatal life was predicted based on fetal atrial M-mode.
