Left ventricular rotational mechanics in identical twins with juvenile idiopathic arthritis (from the MAGYAR-Twin study)

We report the case of a 21-year-old Hungarian genetically identical monozygotic female pair of twins who were involved in Motion Analysis of the heart and Great vessels bY three-dimensionAl (3D) speckle tRacking echocardiography in Twins (MAGYAR-Twin) study. Small joints of the first-born twin (twin A) were affected by early onset seronegative juvenile idiopathic arthritis (JIA) at the age of 10 years (1,2).
