From: Targeted endomyocardial biopsy guided by real-time cardiovascular magnetic resonance

  1. Number (No) of tissue samples obtained by endomyocardial biopsy (EMB) under real-time CMR and under fluoroscopy (Fl), number of trials of biopsies and lesion size in g and in % of total left ventricular (LV) mass are given. No EMB trials were done in the first animal under FL and in the last animal due to large pericardial effusion
