Prevalence, Spectrum, and Outcome of Right Ventricular Outflow Tract Abnormalities in Twin-twin Transfusion Syndrome: A Large, Single-center Experience

Abstract

Right ventricular outflow tract abnormalities impact ∼ 9% of recipient twins in twin-twin transfusion syndrome, many of whom will have persistent abnormalities despite otherwise successful therapy. These data justify efforts to increase awareness and monitoring of the cardiac sequelae of twin-twin transfusion syndrome in these high-risk pregnancies.
