CMR findings
LV-LGE was evident in 23 (29.5%) of the 78 patients, occupying 8.1% ± 8.6% (range: 0.3% to 34.2%) of the LV myocardium. Among patients with LV-LGE, twelve patients (52.2%) showed only one fibrotic area, while 11 (47.8 %) showed multiple fibrotic lesions. LGE areas were linear in 12 (52.2%) patients, patchy in 6 (26.1%), and a combination of the two (n=5, 21.7%) in 23. LGE areas were localized to the ventricular septum (n=18, 78.3%), LV free wall (n=1, 4.3%), or both locations (n=4, 17.4%). LGE distributions were midmyocardial in 20 (87.0%) and non-midmyocardial in 3 (13.0%). An example of a patient without VAs but with LGE is shown in Figure 2 . Another example of a patient with polymorphic VAs and multiple LGE was present in Figure 3 .
Conventional cardiac functional parameters were not associated with VAs occurrence and morphologies (Table 2 ).
