Upset plot summarizing post-LVAD GIB sources among 129 endoscopy cohort patients with complete records. The majority (n=67, 78.3%) did not experience GIB. Among the 62 patients with post-LVAD bleeding, isolated AVM-related bleeding was the predominant pattern, occurring in 29 of 62 cases (46.8%). An inset bar graph in the lower left corner shows the prevalent endoscopic sources of post-LVAD GIB: AVM-related (n=48, 77.4%), mucosal disorder-related (n=17, 27.4%), polyp-related (n=11, 17.7%), diverticulosis-related (n=5, 8.1%), and hemorrhoid-related (n=4, 6.5%)
