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: penicillins / keflex / gentamicin attending: chief complaint: exertional chest discomfort major surgical or invasive procedure: procedure: 1. aortic valve replacement with a 21-mm on-x mechanical aortic valve prosthesis, reference number , serial number . 2. aortic annulus enlargement with a peri-guard bovine pericardial patch, reference number , lot number . 3. pericardial reconstruction using cormatrix xenograft history of present illness: this is a 52yo female with known bicuspid aortic valve and aortic stenosis. she reports mild chest discomfort/burning sensation with activity. serial echocardiograms have shown worsening aortic valve gradients. given that she now reports very mild angina, she has been referred for aortic valve replacment. past medical history: aortic stenosis, bicuspid aortic valve dyslipidemia gerd/heartburn history of migraine ha fatty liver past surgical history: basal cell carcinoma removal cesarean section ectopic pregnancy social history: lives with: husband occupation: -time book keeper. tobacco: denies etoh: denies family history: father cabg @ 57 physical exam: pulse: 80 resp: 16 o2 sat: 100% b/p right: 135/93 left: 133/94 general: wdwn male in no acute distress skin: dry intact heent: perrla eomi neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur 4/6 sem abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema: none varicosities: none neuro: grossly intact pulses: femoral right: 2 left: 2 dp right: 1 left: 1 pt : 1 left: 1 radial right: 2 left: 2 carotid bruit: transmitted murmurs pertinent results: intra-op tee conclusions pre-bypass: 1.the left atrium is mildly dilated. no thrombus is seen in the left atrial appendage. 2.no thrombus is seen in the right atrial appendage 3.no atrial septal defect is seen by 2d or color doppler. 4. there is moderate symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. 5.right ventricular chamber size and free wall motion are normal. 6.the ascending aorta is mildly dilated. the aortic arch is mildly dilated. there are simple atheroma in the descending thoracic aorta. 7.the aortic valve is bicuspid. the aortic valve leaflets are severely thickened/deformed. there is critical aortic valve stenosis (valve area <0.8cm2). trace aortic regurgitation is seen. 8. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. 9. there is a trivial/physiologic pericardial effusion. dr. was notified in person of the results. postbypass: on infusion of phenylephrine and a-pacing for sinus bradycardia. 1. well seated mechanical valve in aortic position. trivial ai probably consistent with normal washing jets. transvalvular gradient is now 15mmhg. 2. preserved biventricular systolic function. 3. aortic contour normal post-decannulation. 04:35am blood wbc-7.4 rbc-2.81* hgb-8.7* hct-25.2* mcv-90 mch-30.9 mchc-34.5 rdw-12.9 plt ct-262 09:00am blood wbc-9.0 rbc-2.83* hgb-8.8* hct-25.2* mcv-89 mch-31.3 mchc-35.1* rdw-13.0 plt ct-210 04:35am blood pt-28.3* ptt-34.4 inr(pt)-2.7* 09:00am blood pt-26.0* ptt-43.0* inr(pt)-2.5* 09:10am blood pt-15.5* ptt-24.8 inr(pt)-1.4* 03:06am blood pt-12.1 ptt-20.0* inr(pt)-1.0 04:35am blood glucose-93 urean-8 creat-0.6 na-137 k-3.8 cl-103 hco3-26 angap-12 09:00am blood urean-7 creat-0.5 na-140 k-3.3 cl-104 brief hospital course: the patient was brought to the operating room on where the patient underwent avr with 21mm on-x mechanical valve as well as aortic root enlargement with a pericardial patch. overall the patient tolerated the procedure well and post-operatively was transferred to the cvicu in stable condition for recovery and invasive monitoring on phenylephrine gtt. pod 1 found the patient extubated, alert and oriented and breathing comfortably. the patient was neurologically intact and hemodynamically stable, weaned from inotropic and vasopressor support. screen for staph aureus was positive and the patient was treated with mupirocin nasal ointment. anti-coagulation was initiated with coumadin and heparin bridge for mechanical valve. beta blocker was initiated and the patient was gently diuresed toward the preoperative weight. the patient was transferred to the telemetry floor for further recovery. chest tubes and pacing wires were discontinued without complication. the patient was evaluated by the physical therapy service for assistance with strength and mobility. by the time of discharge on pod 5, the patient was ambulating freely, the wound was healing and pain was controlled with oral analgesics. inr was therapeutic at 2.7. the patient was discharged home with vna in good condition with appropriate follow up instructions. medications on admission: hydrochlorothiazide -
