Ductal occlusion of 1±5 days duration was diagnosed by fetal echocardiography in our practice over 2 years in 6 of 115 fetuses exposed to indomethacin (mean gestational age 27.4 weeks) at 31±35 weeks' gestation. None was hydropic, and all six had (1) right ventricular enlargement with decreased shortening and tricuspid valve regurgitation; (2) increased main and branch pulmonary artery sizes; and (3) increased left ventricular shortening and aortic arch velocity. Ductal occlusion was differentiated from ductal constriction by an absence of flow in the ductus, seen by color Doppler exa Chapter 37 Evaluation of Pulmonary and Ductal Vasculature 553 Clinical Implications of Ductal Constriction Whether prolonged constriction of the ductus can lead to clinically significant hypertrophy of the smooth muscle in the pulmonary vascular bed is currently under investigation. The right ventricle develops hypertrophy rapidly during constriction, and little is known about its impact on gestation or the postnatal course. It seems prudent to evaluate a fetus exposed to chronic indomethacin at least weekly if there it no evidence of constriction and to increase the surveillance to daily examinations if ductal constriction is present with tricuspid regurgitation. Ductal Occlusion Fig. 37.4. Fetal echocardiography following fetal ductal occlusion of 1 week duration showing residual ductal constriction. Top panel: Ductal constriction is indicated by the persistently elevated velocities. Second panel: There is decreased forward flow in the pulmonary valve and slight pulmonary valve regurgitation, which is never seen in the normal fetus. Third panel: M-mode echocardiography shows residual thickening of the right ventricle. Bottom panel: Left branch of the pulmonary artery (LPA) Doppler velocity is abnormal, with diastolic reversal indicating elevated fetal pulmonary vascular resistance. The fetus resolved this pattern prior to birth and was delivered without complication
