  1. Regarding image quality in patients with Pacemakers: &in 1 patient late gadolinium enhancement (LGE) was graded 2 (“moderate”) due to respiratory motion. ain 1 patient perfusion was not interpretable due to a Valsalva manoeuvre and a contrast media injection into a thrombosed vein. bin 2 exams (6%) the quality was grade 2 (“moderate”) due to respiratory motion
  2. Regarding image quality in patients with ICD: cin 1 exam (3%) quality was grade 3 (“poor”) due to respiratory motion
