Additional file 1: of Myocardial fibrosis by late gadolinium enhancement cardiovascular magnetic resonance in myotonic muscular dystrophy type 1: highly prevalent but not associated with surface conduction abnormality

Table S1. T1 mapping in patients with and without conduction abnormality. Table S2. Patient characteristics according to CMR-LGE findings. Table S3. Electrocardiographic Characteristics According to CMR-LGE findings. Table S4. Full Univariate Logistic Regression Analysis of Variables Associated with Surface Conduction Abnormality. Fig. S1. Representative ECG and CMR findings in the study cohort including T1 mapping. Panels A shows an patient with abnormal ECG with prolonged PR interval and right bundle branch block, his corresponding native T1 map in panel B (utilizing MOLLI 3(3)3(3)5) and post-contrast T1 map in panel C yielding an ECV of 24%. Panel D demonstrates septal and inferolateral midwall fibrosis in the same patient. Panel E demonstrates a patient without conduction abnormality; his pre- and post-contrast T1 maps in panels F and G (utilizing MOLLI 5(3)3) yield an ECV of 23% and panel H demonstrates fibrosis in the inferior RV insertion site
