This unique property of Fontan circulation may be related to decreased exercise tolerance or increased instantaneous postoperative mortality rate, often observed in patients with this circulation. To better understand Fontan physiology, the present(More)

Well-differentiated adenomatous polyps in the anorectal junction were larger in average size than ordinary colorectal polyps having the same grade of epithelial(More)
