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: no known allergies / adverse drug reactions attending: chief complaint: mild exertional dyspnea major surgical or invasive procedure: s/p avr (#21mm st. epic)/asc ao replacement history of present illness: this is a 69 year old female with known aortic stenosis since . she has experienced a slight increase in exertional dyspnea. she was recently assessed by an exercise tolerance test and echocardiogram which revealed more severe aortic stenosis. at times, the patient is aware of brief flutters which occur at night without lightheadedness, dizziness, presyncope or syncope. she denies effort related chest pain. she remains very active, and performs routine daily activities without difficulty. she was seen by dr. in for surgical discussion. she presents today for preadmission testing for an aortic valve replacement with possible ascending aorta replacement with dr. . past medical history: aortic stenosis history of mitral valve prolapse hypertension dyslipidemia obesity pernicious anemia hypothyroidism osteoarthritis peripheral neuropathy chronic back pain, degenerative scoliosis lumbosacral radiculitis - prior thoracic block past surgical history: - lap cholecystectomy - multiple lumbar and thoracic spine fusions(approx nine) one c/b likely mrsa - left cataract surgery, (right cataract scheduled for ) - fibroid removal - mohs social history: last dental exam: race: caucasian lives with: husband occupation: retired, very active golfer cigarettes: never etoh: < 1 drink/week drinks/week >8 drinks/week illicit drug use: denies

transmitted murmurs pertinent results: echocargiogram : pre-bypass: the left atrium is normal in size. no spontaneous echo contrast or thrombus is seen in the body of the left atrium or left atrial appendage. no atrial septal defect is seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. regional left ventricular wall motion is normal. overall left ventricular systolic function is normal (lvef>55%). right ventricular chamber size and free wall motion are normal. the ascending aorta is mildly dilated. there are simple atheroma in the ascending aorta, aortic arch, and 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 to moderate (+) mitral regurgitation is seen. there is very small pericardial effusion. post-bypass: the patient is on a phenylephrine infusion s/p aortic vavle and ascending aortic plication. there is a well seated #21 bioprosthetic aortic valve. there are no perivalvular leaks. peak and mean gradients are 14/7 with a cardiac output of 3.6. left ventricular function is preserved with estimated ef-55% mitral regurgitaion appears slightly worse (mild-mod mr). tricuspid reguritaiton remains +. there is no echocardiographic evidence or aortic dissection post-decannulation. . 06:09am blood wbc-6.8 rbc-2.73* hgb-8.7* hct-26.0* mcv-95 mch-31.8 mchc-33.4 rdw-14.7 plt

underwent aortic valve(#21mm st. epic tissue)/ascending aortic replacement . overall the patient tolerated the procedure well and post-operatively was transferred to the cvicu in stable condition for recovery and invasive monitoring. she arrived ap over sb and was hypertensive required nitro gtt. she was initially hypoxic and required extra vent support, she eventually extubated without difficulty. pod 1 found the patient extubated, alert and oriented and breathing comfortably. the patient was neurologically intact and hemodynamically stable, weaned from the nitro. beta blocker was initiated and the patient was gently diuresed toward the preoperative weight. she became hypoglycemic after receiving lantus per icu protocol and remained in the unit one extra day for monitoring. she was hypotensive and beta blocker was adjusted. the patient was transferred to the telemetry floor on pod#2 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 with vna in good condition with appropriate follow up instructions. medications on admission: atorvastatin 40 mg daily,
