Fetal and neonatal echocardiographic findings in twin-twin transfusion syndrome

Serial Doppler echocardiography was conducted with 17 monochorionic twin pregnancies to determine kinds of cardiac involvement associated with twin-twin transfusion syndrome. Cardiovascular state of the donor twins was normal, while the recipient twins exhibited variable severity of biventricular hypertrophy and dilation with tricuspid regurgitation. Cardiac impairments were reversible after the fluid imbalances were corrected by decompressive amniocenteses or after birth.
