PI's: Shiraz Maskatia, MD | Lucile Packard Children’s Hospital

Specific Aims:

• Define the incidence of mitral regurgitation in the setting of advanced twin-twin transfusion syndrome.
• Define the association of mitral regurgitation and perinatal mortality and morbidity in monochorionic, diamniotic twin fetuses with advanced (Stage III-IV) twin-twin transfusion syndrome and compare the strength of association of mitral regurgitation with perinatal mortality to other identified risk factors in this disease process.
