Upset plot summarizing pre-LVAD endoscopic results for 129 patients with complete records. The plot reveals 101 patients (78.3%) with positive findings. The most common pattern of pre-LVAD screening finding was isolated polyps, which were found in 30 of 129 (23.3%) of all screened patients. An inset bar graph in the lower left corner shows that the most prevalent pathologic pre-LVAD finding was polyps (n=59, 58.4%), followed by diverticulosis (n=27, 26.7%), mucosal-related disorder (n=26, 25.7%), hemorrhoids (n=24, 23.8%), and AVMs (n=7, 6.9%)
