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: fatigue major surgical or invasive procedure: coronary artery bypass grafting time one, aortic valve replacement with 25 mm mosaic ultra porcine history of present illness: mr. is a 64 year old man followed for several years for a bicuspid aortic valve and aortic stenosis. his most recent echocardiogram showed worsening stenosis. therefore he was referred to cardiac surgery. past medical history: bicuspid aortic valve aortic valve stenosis ascending aortic arch aneurysm left inguinal hernia mild benign prostatic hypertrophy sleep apnea on cpap s/p right inguinal hernia repair bilateral cataract surgery social history: mr. is an attorney. family history: his family history is non-contributory. physical exam: at the time of admission, mr was found to be in no acute distress. his skin was noted to be warm, dry, and clean, dry, and intact. his teeth were noted to be in good repair. no jugular venous distention was noted. upon auscultation of his chest, his lungs were clear to auscultation bilaterally. his heart was of regular rate and rhythmwith a iii/vi systolic ejection murmur. his abdomen was soft, non-tender, and non-distended with a left sided direct inguinal hernia. his lower extremities were slightly edematous. mild varicosities below the knee were found. he was awake, alert, and oriented with a steady gate. pertinent results: 02:41am blood wbc-13.8* rbc-3.60* hgb-11.3* hct-32.5* mcv-90 mch-31.5 mchc-34.9 rdw-12.9 plt ct-168 02:41am blood plt ct-168 02:41am blood glucose-108* urean-10 creat-0.8 na-137 k-5.1 cl-111* hco3-23 angap-8 10:28am blood wbc-7.8 06:15am blood urean-9 creat-0.9 na-138 k-4.1 echocardiography report , portable tte (complete) done at 12:30:00 pm final referring physician information , r. , division of cardiothorac , status: inpatient dob: age (years): 65 m hgt (in): 72 bp (mm hg): 102/60 wgt (lb): 180 hr (bpm): 81 bsa (m2): 2.04 m2 indication: pericardial effusion. icd-9 codes: 424.1 test information date/time: at 12:30 interpret md: , md test type: portable tte (complete) son: , rdcs doppler: full doppler and color doppler test location: / 6 contrast: none tech quality: adequate tape #: 2009w000-0:00 machine: vivid i-3 echocardiographic measurements results measurements normal range left atrium - long axis dimension: *4.3 cm <= 4.0 cm left atrium - four chamber length: 4.5 cm <= 5.2 cm right atrium - four chamber length: *5.1 cm <= 5.0 cm left ventricle - ejection fraction: >= 55% >= 55% aorta - sinus level: *4.3 cm <= 3.6 cm aorta - ascending: *4.6 cm <= 3.4 cm aortic valve - peak velocity: *3.1 m/sec <= 2.0 m/sec aortic valve - peak gradient: *39 mm hg < 20 mm hg aortic valve - mean gradient: 24 mm hg mitral valve - e wave: 0.8 m/sec mitral valve - a wave: 0.9 m/sec mitral valve - e/a ratio: 0.89 mitral valve - e wave deceleration time: *367 ms 140-250 ms tr gradient (+ ra = pasp): 19 mm hg <= 25 mm hg findings left atrium: mild la enlargement. right atrium/interatrial septum: mildly dilated ra. left ventricle: normal lv wall thickness, cavity size, and global systolic function (lvef>55%). no resting lvot gradient. right ventricle: normal rv chamber size and free wall motion. aorta: moderately dilated aortic sinus. moderately dilated ascending aorta. aortic valve: bioprosthetic aortic valve prosthesis (avr). avr well seated, normal leaflet/disc motion and transvalvular gradients. trace ar. mitral valve: mildly thickened mitral valve leaflets. mild mitral annular calcification. trivial mr. tricuspid valve: normal tricuspid valve leaflets. mild tr. normal pa systolic pressure. pulmonic valve/pulmonary artery: pulmonic valve not well seen. pericardium: no pericardial effusion. general comments: left pleural effusion. conclusions the left atrium is mildly dilated. left ventricular wall thickness, cavity size, and global systolic function are normal (lvef>55%). right ventricular chamber size and free wall motion are normal. the aortic root is moderately dilated at the sinus level. the ascending aorta is moderately dilated. a bioprosthetic aortic valve prosthesis is present. the aortic valve prosthesis appears well seated, with normal leaflet/disc motion and transvalvular gradients. trace aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. the estimated pulmonary artery systolic pressure is normal. there is no pericardial effusion. impression: no significant pericardial effusion. normally-functioning aortic valve bioprosthesis. electronically signed by , md, interpreting physician 14:44 ??????
