*Number of segments with abnormal wall motion of 13 analysed segments.
DE‐MRI, delayed‐enhancement magnetic resonance imaging; F, female; M, male; Mus, Mustard operation; ND, not done; OP, heart surgery; PET, positron emission tomography; RVEF, right ventricular ejection fraction determined by magnetic resonance imaging; S, Senning operation; SR, sinus rhythm; SSS, sick sinus syndrome; TR, grade of tricuspid regurgitation determined by echocardiography.25
None of the patients with relatively small RVEF or with many segments with wall motion abnormalities had myocardial scars.
