Characterization of Diastolic Dysfunction in Twin-Twin Transfusion Syndrome: Association between Doppler Findings and Ventricular Hypertrophy

Concentric hypertrophy is observed in RTs affected by TTTS and is associated with impaired ventricular relaxation and shortened filling time. In severe cases, further decreases in diastolic filling time and Doppler signs of elevated ventricular filling pressures are present.
