Echocardiographic data obtained before and after the procedure were analyzed retrospectively (median interval after intervention, 1 (range, 1\u20133) days) for ventricular and valvular dimensions and ratios, RV filling time (duration of tricuspid valve (TV) inflow\/cardiac cycle length), TV velocity time integral (TV\u2010VTI)\u2009\u00d7\u2009heart rate (HR) and tricuspid regurgitation (TR) velocity. Longitudinal data were collected from only those fetuses followed up in our center. Outcome was assessed using the scoring system as described by Roman\n et al<\/jats:italic>\n . for non\u2010biventricular outcome.\n <\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n Thirty\u2010five pulmonary valvuloplasties were performed in our institution on 23 fetuses with PAIVS (\n n<\/jats:italic>\n \u2009=\u200915) or CPS (\n n<\/jats:italic>\n \u2009=\u20098). Median gestational age at intervention was 28\u2009+\u20094 (range, 23\u2009+\u20096 to 32\u2009+\u20091) weeks. No fetal death occurred. Immediately after successful intervention, RV\/left ventricular length (RV\/LV) ratio (\n P<\/jats:italic>\n \u2009\u2264\u20090.0001), TV\/mitral valve annular diameter (TV\/MV) ratio (\n P<\/jats:italic>\n \u2009\u2264\u20090.001), RV filling time (\n P<\/jats:italic>\n \u2009\u2264\u20090.00001) and TV\u2010VTI\u2009\u00d7\u2009HR (\n P<\/jats:italic>\n \u2009\u2264\u20090.001) increased significantly and TR velocity (\n P<\/jats:italic>\n \u2009\u2264\u20090.001) decreased significantly. In fetuses followed longitudinally to delivery (\n n<\/jats:italic>\n \u2009=\u20095), RV\/LV and TV\/MV ratios improved further or remained constant until birth. Fetuses with unsuccessful intervention (\n n<\/jats:italic>\n \u2009=\u20092) became univentricular, all others had either a biventricular (\n n<\/jats:italic>\n \u2009=\u200915), one\u2010and\u2010a\u2010half ventricular (\n n<\/jats:italic>\n \u2009=\u20093) or still undetermined (\n n<\/jats:italic>\n \u2009=\u20093) outcome. Five of nine fetuses with a predicted non\u2010biventricular outcome, in which the procedure was successful, became biventricular, while two of nine had an undetermined circulation.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusion<\/jats:title>\n \n In selected fetuses with PAIVS or CPS,\n in\u2010utero<\/jats:italic>\n pulmonary valvuloplasty led immediately to larger RV caused by reduced afterload and increased filling, thus improving the likelihood of biventricular outcome even in fetuses with a predicted non\u2010biventricular circulation. \u00a9 2018 The Authors.\n Ultrasound in Obstetrics &
