Fig 2. Association between ventricular inducibility and myocardial fibrosis detected in endomyocardial biopsy.

A. There was no association between the presence and amount of myocardial fibrosis described in histopathology and ventricular inducibility during programmed ventricular stimulation (p = 1.00). B. The upper panel of Fig 2B illustrates an example of severe myocardial fibrosis in endomyocardial biopsy detected by picrosirius red staining in a patient with non-ischemic dilated cardiomyopathy and no inducible ventricular arrhythmias. The lower panel depicts the histology of healthy myocardium with a fibrosis area of <3%.
