Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: aspirin attending: chief complaint: shortness of breath major surgical or invasive procedure: aortic valve replacement with a 29-mm mosaic ultra bioprosthesis. replacement of ascending aorta with a 30-mm dacron tube graft using deep hypothermic circulatory arrest which included hemi-arch replacement. history of present illness: year old male known to our service (see previous notes) who has a history of severe as ( 0.8cm2), htn, chronic gi bleeding ( avms, uc) requiring frequent transfusion, myelodysplastic syndrome s/p recent chemotherapy. he has been undergoing work-up for potential aortic valve replacement and asc. aorta repl. he first needed neuro clearance after new left foot drop. neuro decided foot drop is related to peroneal nerve lesion. given his complex gi history, he was also waiting gi clearance and to make sure that his colitis was in control and hopefully off steroids. following cardiac surgery, it was recommended that he have a colectomy because of the ulcerative colitis and a large polyp that is almost to the anal verge. there are multiple other polyps that are also adenomas. he now presents again in clinic for further discussion of surgery. past medical history: - severe aortic stenosis - hypertension - hyperlipidemia - systolic congestive heart failure - benign prostatic hypertrophy - ulcerative colitis with recurrent gi bleeding on sulfasalazine - gastric avms s/p gi bleed, admitted on to - myelodysplastic syndrome, tx with vidaza - prostate cancer in 's - left foot drop - common peroneal nerve lesion, likely at the fibular head. wears foot orthosis and foot drop splint. - s/p b/l cataract extraction and lens implants social history: race: caucasain last dental exam: edentulous lives with: wife occupation: retired carpenter cigarettes: smoked no yes hx:quit smoking 50 years ago and smoked for 20 years other tobacco use: denies etoh: < 1 drink/week drinks/week >8 drinks/week illicit drug use: denies family history: daughter -
