Prenatal and postnatal imaging of thoracopagus conjoined twins with a shared six-chamber heart.
Management of thoracopagus conjoined twins is predominantly determined by the associated complex cardiovascular abnormalities seen in the majority of these cases. Magnetic resonance imaging (MRI), including three-dimensional contrast-enhanced magnetic resonance angiography (MRA) provides a useful complement to conventional cardiac echocardiography or catheterization for detailed evaluation of the extra-cardiac anatomy. We report a pair of female thoracopagus conjoined twins with a shared six-chambered heart. The MRA findings are highlighted.
