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: anacin attending: chief complaint: shortness of breath major surgical or invasive procedure: mitral valve replacement(27mm mosaic tissue valve) via right thoracotomy history of present illness: 64 year old male with progressive exertional shortness of breath over the last month. he was undergoing cardiac workup and presented at osh for stress test in atrial flutter, he was admitted and underwent cardiac catherization and echocardiogram that revealed cad and mod-severe mitral regurgitation. transferred for cardiac surgery past medical history: coronary artery disease s/p cabg mitral regurgitation atrial flutter hypertrophic cardiomyopathy chronic ischemic heart disease hypertension myxomatous mitral valve disease anxiety disorder (panic attacks) elevated cholesterol social history: married, lives with spouse full time as meat salesman tobacco 40 pack year history quit in etoh denies family history: father and grandfather both with coronary artery disease dx in their 60's physical exam: general no acute distress, well nourished skin intact, old sternal, right calf and left ankle incisions healed. right groin s/p cath soft no hematoma, no bruit heent perrla, eomi neck: supple, full rom, no lymphadenopathy chest cta bilat ant/post heart rrr, sys murmur no rub/gallop abd soft, nt, nd +bs, no palpable masses ext warm no edema no varicosities pulses +2 dp/pt/rad/fem, carotids -?murmur neuro nonfocal a/ox3 mae 5/5 strength pertinent results: 12:50pm pt-12.5 ptt-27.3 inr(pt)-1.1 12:50pm plt count-289 12:50pm wbc-5.5 rbc-4.43* hgb-11.6* hct-33.1* mcv-75* mch-26.3* mchc-35.2* rdw-14.7 12:50pm alt(sgpt)-29 ast(sgot)-34 ld(ldh)-184 alk phos-189* tot bili-0.7 12:50pm glucose-120* urea n-11 creat-0.9 sodium-139 potassium-4.5 chloride-106 total co2-25 anion gap-13 03:22pm urine blood-neg nitrite-neg protein-neg glucose-neg ketone-neg bilirubin-neg urobilngn-neg ph-6.0 leuk-neg echo prebypass: no spontaneous echo contrast is seen in the left atrial appendage. no atrial septal defect is seen by 2d or color doppler. there is mild global right ventricular hypokinesis. lv apical hypokinesis is noted- the remaining left ventricular segments contract normally.the ascending thoracic aorta is normal in diameter and free of atherosclerotic plaque. there are simple atheroma in the descending thoracic aorta. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. the mitral valve leaflets are mildly thickened. moderate to severe (3+) mitral regurgitation is seen. the mitral regurgitation jet is eccentric and anteriorly directed.. moderate tricuspid regurgitation is seen. there is no pericardial effusion. post bypass: global rv and lv apical function improved. mvr investigated - no mr noted, appropriate valve seating with struts in good postion. peak valve gradient 12. descending and ascending aorta without defect or flap dissection, aortic valve without ai. cxr pa and lateral chest views obtained with patient in upright position demonstrate status post sternotomy and the presence of multiple surgical clips in the anterior mediastinum consistent with previous bypass surgery. in addition 3 small ring-shaped metallic structures indicate the presence of a mitral valve prosthesis in appropriate position. comparison is made with the previous chest examination of at that time described persistent elevation of the right-sided hemidiaphragm and evidence of pleural thickening mostly on the right side remains rather unchanged. when comparison is made with the preoperative chest examination dated , i.e. prior to mitral valve replacement evidence of sternotomy and bypass surgery existed already. the now persisting elevation of the diaphragmatic contour and adhesions surrounding the right lower lobe area are new. further follow up is recommended. ospital course: mr. was transferred to the floor from . he was seen in consultation by dental medicine and was cleared for surgery. he was started on heparin for his atrial fibrillation. he underwent pfts. he was taken to the operating room on where he underwent an mvr with a 27 mm mosaic tissue valve via a right thoracotomy. postoperatively he was taken to the sicu in stable condition. he awoke and was extubated later that same day. he was weaned from his vasoactive drips and transferred to the floor on pod #1. he did well post operatively. on pod #2, he was found to have a prolonged pr interval to .4, for which he was seen by electrophysiology. his beta blocker was subsequently discontinued. he developed atrial fibrillation and flutter and coumadin was subsequently started. his electrolytes were repleted and he converted back to normal sinus rhythm.the physical therapy service worked with him daily to increase his postoperative strength and mobility. he was gently diuresed towards his preoperative weight. mr. continued to make steady progress and was discharged home on postoperative day six. he will follow-up with dr. , his cardiologist and his primary care physician as an outpatient. his coumadin will be followed by heart center's coumadin clinic for an inr goal of 2.0-3.0. medications on admission: toprol xl 50mg daily folic acid 1mg daily ecasa 325mg daily xanax 0.25mg prn panic attacks (3-4x/wk) ultram prn pain discharge medications: 1. 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:*0* 2. ranitidine hcl 150 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*0* 3. ferrous sulfate 325 (65) mg tablet sig: one (1) tablet po daily (daily). disp:*30 tabs* refills:*0* 4. tamsulosin 0.4 mg capsule, sust. release 24hr sig: one (1) capsule, sust. release 24hr po hs (at bedtime). disp:*30 capsule, sust. release 24hr(s)* refills:*0* 5. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*50 tablet(s)* refills:*0* 6. ascorbic acid 500 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*0* 7. warfarin 5 mg tablet sig: one (1) tablet po once (once): take one tablet daily. disp:*30 tablet(s)* refills:*2* discharge disposition: home with service facility: vna discharge diagnosis: mitral regurgitation -

Answer: The patient is high likely exposed to
