The purpose of this study is to clarify the actual condition of gastrointestinal vascular dysplasia associated with cardiovascular disease.
Others
To clarify the risk factors for gastrointestinal vascular dysplasia associated with cardiovascular disease.
Perform gastrointestinal endoscopy to evaluate the presence, size, morphology, number, and site of onset of gastrointestinal angiodysplasia.
Obtain the von Willebrand factor (VWF) polymer multimer index. In addition, comprehensive hemostatic analysis of VWF antigen amount, VWF activity, PAI-1, soluble thrombomodulin, etc. will be performed.

Diagnosis
Maneuver |
A ,Aortic valve stenosis (AS)
For cases of AS, EGD/CS/CE are provided as insurance medical treatment before TAVI if the condition permits, but within 1 month after TAVI for cases with poor condition such as heart failure. In addition, one year after TAVI (10 to 14 months later), follow-up examination will be performed only for EGD/CS/CE that had previously confirmed gastrointestinal mucosal vascular dysplasia.
B, Mitral regurgitation (MR)
For cases of MR, EGD/CS/CE will be performed as insurance medical treatment at the time of registration.
C, New implantable left ventricular assist device (LVAD) placement case
LVAD are presumed to be associated with severe heart failure, and it is difficult to perform endoscopy before surgery. Therefore, CE is performed within 1 month of indwelling (free of charge as a study). CE 6 months after LVAD placement (4-8 months), 1 and a half years (16-20 months), and preferably 3-4 years (30-48 months) Follow up. The frequency of gastrointestinal bleeding did not decrease even several years after LVAD placement, and we would like to perform CE 3-4 years later (30-48 months later) to evaluate vascular dysplasia. Purchase of CE Research expenses have not been secured. Therefore, at present, it will be enforced if possible.
D, Gastrointestinal bleeding of unknown cause
Gastrointestinal bleeding cases of unknown causeare registered, and CE is performed as insurance medical treatment. In addition, follow-up CE will be performed only for those who had dysplasia of the gastrointestinal mucosa at the time of splenic bleeding 6 to 24 months after the initial examination.
A,B,C,D
Before CE, we perform patency capsules (PCE) as much as possible (insurance medical treatment). At the same time as endoscopy, additional blood is collected at the time of blood collection within the normal medical care range and thrombotic hemostatic analysis is performed. Evaluate cardiac function at the same time as endoscopy.

Male and Female
A)Aortic stenosis with anemia
(Aortic valve implantation (TAVI) cases with a catheter of hemoglobin <11.0 g / dL) 200 cases
B)30 cases of mitral regurgitation with anemia (hemoglobin <11.0 g / dL)
(AVWS also develops in mitral regurgitation, but hemodynamics are different from aortic stenosis. Therefore, mitral regurgitation is also targeted to determine the effect of hemodynamics.)
C)LVAD implantation cases:25 cases
D)Gastrointestinal bleeding of unknown cause (no obvious source of bleeding such as cancer, ulcer, inflammation, diverticulum): 50 cases
1) Cases with apparently serious infections and inflammation
2) Cases with serious complications (intestinal paralysis, intestinal obstruction, etc.)
3) Instability of hemodynamics
4) After gastrointestinal surgery (Post appendectomy is OK)
5) Cases suspected of gastrointestinal stenosis
6) Advanced cancer
7) Cases where other causes of anemia, such as cancer, cancer treatment, and blood disorders, can be found
8) Cases of inflammatory bowel disease
9) Other cases that doctors deem inappropriate for this study
