We report a case of chronic mesenteric ischemia associated with severe aortic valve regurgitation and stenosis(ASR). The patient was a 76-year-old man who had been given a diagnosis of ASR in his 40s. He gradually developed heart failure and chronic kidney disorder due to deterioration of ASR. He had started hemodialysis 1 year before admission and had complained of abdominal pain after meals and weight loss during that period. He was admitted to the Department of Cardiology in our hospital for evaluation of ASR. Severe ASR with low output syndrome(C. I. 2.00 L/min/m2)were confirmed by cardiac catheter examination. In addition, abdominal angiography revealed total occlusion of the superior mesenteric artery(SMA)and severe stenosis of the celiac artery(CA). We considered that low cardiac output due to severe ASR had exacerbated the mesenteric ischemia. We performed AVR and abdominal aorta-SMA bypass at the same time to prevent acute mesenteric ischemia in the perioperative period. The combination of valvular disease and CMI is very rare. This is the first report in Japan of simultaneous valve replacement and mesenteric artery revascularization.
