Recently, an interesting study was published, in which FFR was performed to diagnose and guide stenting in chronic mesenteric ischemia （CMI）. We herein highlighted, the implications and limitations of FFR from coronary artery to renal artery and mesenteric artery for future investigations, respectively.展开更多
