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: patient recorded as having no known allergies to drugs attending: chief complaint: occassional chest pressure major surgical or invasive procedure: aortic valve replacement (21mm pericardial) history of present illness: mr. is a 68-year-old male with worsening symptoms of dyspnea on exertion and chest tightness, who has been followed with a known aortic stenosis. echocardiogram showed an aortic valve area estimated at 0.6 square cm. a cardiac catheterization confirmed critical aortic stenosis with a high-grade in the normal coronary arteries. he is presenting for aortic valve replacement. past medical history: osteoarthritis basal cell cancer right hip replacement social history: lives with wife. owns a retail store. smoked for 25 years quitting 25 years ago. family history: non-contributory physical exam: 58 sr 120/77 66" 183 pounds gen: well developed well nourished in no distress skin: no lesions or rash heent: normocephalic/atraumatic, pupils equal, round and reactive. neck: supple. transmitted bruit versus radiated murmur chest: clear heart: regular rate and rhythm, iii/vi systolic murmur abd: soft, nontender, nondistended ext: warm well perfused. no edema, 2+ pulses. neuro: nonfocal pertinent results: 05:45am blood wbc-5.0 rbc-3.06* hgb-9.1* hct-27.4* mcv-90 mch-29.6 mchc-33.0 rdw-14.3 plt ct-103* 05:25am blood pt-12.4 ptt-24.7 inr(pt)-1.0 05:25am blood urean-17 creat-0.9 k-4.3 05:25am blood mg-2.1 04:55am blood glucose-160* k-4.1 cxr 1) small bilateral pleural effusions. 2) clear lungs. ekg sinus rhythm. extensive st elevation suggests pericarditis since previous tracing of , st changes seen brief hospital course: mr. was admitted to the medical center electively for surgery on . he was taken directly to the operating room where he underwent an aortic valve replacement utilizing a 21mm pericardial bioprosthesis. postoperatively he was taken to the cardiac surgical intensive care unit for monitoring. on postoperative day one, mr. neurologically intact and was extubated. he developed atrial fibrillation which was treated with beta blockade. he was anticoagulated with coumadin for his atrial fibrillation. amiodarone was subsequently started with conversion to normal sinus rhythm. two units of packed red blood cells were transfused for postoperative anemia. on postoperative day three, mr. was transferred to the cardiac surgical step down unit for further recovery. he was gently diuresed towards his preoperative weight. the physical therapy service was consulted for assistance with his strength and postoperative mobility. as mr. remained in normal sinus rhythm, his coumadin was discontinued. his drains and wires were removed per protocol. mr. continued to make steady progress and was discharged home on postoperative day four. he will follow-up with dr. , his cardiologist and his primary care physician as an outpatient. medications on admission: advil and tylenol as needed discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*0* 2. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*2* 3. hydrocodone-acetaminophen 5-500 mg tablet sig: 1-2 tablets po q4-6h (every 4 to 6 hours) as needed. disp:*50 tablet(s)* refills:*0* 4. amiodarone hcl 200 mg tablet sig: two (2) tablet po bid (2 times a day): 400mg x7days then 400mg qd x7 days then 200mg qd. disp:*60 tablet(s)* refills:*2* 5. furosemide 20 mg tablet sig: one (1) tablet po daily (daily) for 10 days. disp:*10 tablet(s)* refills:*0* 6. potassium chloride 20 meq tab sust.rel. particle/crystal sig: one (1) tab sust.rel. particle/crystal po daily (daily) for 10 days. disp:*10 tab sust.rel. particle/crystal(s)* refills:*0* 7. metoprolol tartrate 25 mg tablet sig: 0.5 tablet po bid (2 times a day). disp:*30 tablet(s)* refills:*2* discharge disposition: home with service facility: vna discharge diagnosis: - status post aortic valve replacement (#21 pericardial) discharge condition: good discharge instructions: keep wounds clean and dry, ok to shower, no bathing or swimming. take all medications as prescribed. call for any fever, redness or drainage from wounds followup instructions: wound clinic in 2 weeks dr in weeks dr in 4 weeks procedure: extracorporeal circulation auxiliary to open heart surgery open and other replacement of aortic valve with tissue graft continuous intra-arterial blood gas monitoring diagnoses: cardiac complications, not elsewhere classified atrial fibrillation aortic valve disorders personal history of other malignant neoplasm of skin hip joint replacement 

Answer: The patient is high likely exposed to
