The effect of fetoscopic laser therapy on fetal cardiac size in twin-twin transfusion syndrome

Objectives To evaluate the influence of fetoscopic laser therapy on fetal cardiac size in monochorionic twins complicated by twin–twin transfusion syndrome (TTTS). Methods In a longitudinal, prospective study, we assessed fetal cardiac size sonographically in monochorionic diamniotic twins with TTTS treated by laser therapy and in monochorionic twins without TTTS. The fetal cardiothoracic ratio (cardiac circumference divided by thoracic...
