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: prevpac / tetanus attending: chief complaint: dyspnea on exertion major surgical or invasive procedure: aortic valve replacement (27mm mosaic), coronary artery bypass x 3 (lima-lad, svg-dx, svg-rca) history of present illness: 74 year old male with known aortic stenosis with bicuspid valve (peak gradient was 54 mmhg, the mean gradient was 32 mmhg and the valve area was 0.9-1.0 cm2, noted for worsening dyspnea on exertion.) reports worsening dyspnea on exertion relieved with rest, associated with bilateral shoulder pain. this has been occuring for about one year and worsened over the last past four months. past medical history: aortic stenosis, coronary artery disease pmh: sleep apnea-does not use cpap hypertension bicuspid aortic valve/aortic stenosis hyperlipidemia vertigo gastroesophageal reflux disease stage iii kidney disease appendectomy benign prostatic hyperplasia social history: lives with: spouse occupation: custodian tobacco: quit 30 years ago 25 pack year history etoh: 3 oz scotch x week family history: mother ? valve problem physical exam: pulse: 48 resp: 12 o2 sat: 96% b/p right: 167/98 left: 180/93 height: weight: general: no acute distress skin: dry intact heent: perrla eomi neck: supple full rom decreased range from arthritis -

no spontaneous echo contrast is seen in the left atrial appendage. - overall left ventricular systolic function is low normal (lvef 50-55%). - right ventricular chamber size and free wall motion are normal. - there are simple atheroma in the descending thoracic aorta. - the aortic valve is bicuspid. the aortic valve leaflets are severely thickened/deformed. - there is critical aortic valve stenosis (valve area <0.8cm2). - no aortic regurgitation is seen. - the mitral valve leaflets are mildly thickened. - mild (1+) mitral regurgitation is seen. - there is no pericardial effusion. - ascending aorta 3.6cm diameter postbypass - prosthetic aortic valve without perivalvular leak or regurgitation - mean pressure gradient across aortic valve 7-10mmhg - biventricular systolic function remains preserved with left ventricular ef 50-55% - mild mitral regurgitation - aorta intact 07:10pm blood wbc-9.8 rbc-3.36* hgb-10.4* hct-29.4* mcv-87 mch-31.0 mchc-35.5* rdw-13.5 plt ct-116* 07:10pm blood glucose-122* urean-23* creat-1.4* na-140 k-4.9 cl-104 hco3-30 angap-11 03:06am blood glucose-104* urean-22* creat-1.3* na-138 k-4.1 cl-105 hco3-27 angap-10 brief hospital course: the patient was admitted to the hospital and brought to the operating room on where the patient underwent aortic valve replacement with a 23-mm mosaic ultra valve bioprosthesis as well as coronary artery bypass x 3. overall the patient tolerated the procedure well and post-operatively was transferred to the cvicu in stable condition for recovery and invasive monitoring. cefazolin was used for surgical antibiotic prophylaxis. pod 1 found the patient extubated, alert and oriented and breathing comfortably. the patient was neurologically intact and hemodynamically were supported with neo-synephrine. neo was weaned and the patient remained hemodynamically stable. 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 4 the patient was ambulating freely, the wound was healing and pain was controlled with oral analgesics. the patient was discharged home in good condition with vna services and appropriate follow up instructions. medications on admission: acetylcysteine -
