Hi all,

We are following a case of idiopathic ductal constriction at 34+ weeks. She was initially thought to have pulmonic stenosis at 32 weeks when an enlarged right atria, enlarged right ventricle, and moderate tricuspid regurgitation were identified. On the second fetal echo it was suspected that it was ductal constriction. The echocardiographic criteria for fetal ductal constriction include the presence, at color Doppler, of a turbulent flow in the ductus arteriosus, with a maximal peak systolic velocity exceeding 1.4m/sec, a maximal diastolic velocity higher than 0.3m/s and a pulsitility index lower than 1.9 (or 2.1). The patient was not exposed to indomethacin or nimesulide therapy. She was questioned about her intake of polyphenol-rich foods which was also negative. Does anyone have much experience with this clinical disorder?
