Summary
The purpose of this study is to evaluate the efficacy of KARL STORZ curved fetoscope (11508AAK) and its straight version (11506AAK) for laser photocoagulation of placental anastomoses in patients with an anterior placenta and Twin to Twin Transfusion Syndrome (TTTS).

Interventions
- DeviceCurved KARL STORZ fetoscope
The KARLZ STORZ curved scope is used to see the inside of a pregnant person's uterus during minimally invasive surgery, similar to conventional scopes. The curved scope is rounded and thought to help visualize the anterior placenta because of its position on the uterus.
- DeviceConventional Scopes
The conventional scopes are regularly used during laser photocoagulation of placental anastomoses.
