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 / codeine sulf / morphine / bactrim attending: chief complaint: presyncope major surgical or invasive procedure: aortic valve replacment history of present illness: 84 year old female know to our service (see previous h&p) with past medical history notable for hypertension, hyperlipidemia and severe aortic stenosis. she has had two episodes of lightheadedness causing her to fall to the floor over the past 8 weeks. her most recent echo is from which revealed a normal left atrium, a normal left ventricle with an lvef of >55%, severe aortic stenosis with a valve area of 0.7 cm2, moderate aortic regurgitation and mild to moderate mitral regurgitation. cardiac catheterization revealed similar results with no coronary disease. past medical history: aortic stenosis hypertension hyperlipidemia cervical spondylosis arthritis gastroesophageal reflux disease vascular dementia migraines (no for many years) s/p left cataract surgery social history: race: caucasian last dental exam: few wks ago, partial lowers lives with: daughter occupation: retired tobacco: denies etoh: denies family history: two brothers died from cad (58 & 68) physical exam: height: 65" weight: 135lb general: well-developed female in no actue distress skin: dry intact heent: perrla eomi wears sun-glasses d/t sensitivity neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur 3/6 sem abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema: none varicosities: superficial 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 right: - left: - pertinent results: echo: prebypass: 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 descending thoracic aorta is mildly dilated. there are three aortic valve leaflets. the aortic valve leaflets are severely thickened/deformed. there is critical aortic valve stenosis (valve area <0.8cm2). moderate to severe (3+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. postbypass: biventricular systolic function remains normal. there is a well seated, well functioning bioprostheis in the aortic position. no ai is visualized. the remaining study is unchanged from prebypass. 08:05am blood wbc-13.7* rbc-3.30* hgb-10.3* hct-28.9* mcv-88 mch-31.2 mchc-35.6* rdw-14.2 plt ct-452* 04:25am blood pt-28.4* ptt-27.3 inr(pt)-2.7* 08:05am blood pt-20.2* inr(pt)-1.8* 05:00am blood pt-14.0* inr(pt)-1.2* 04:50am blood pt-12.8 inr(pt)-1.1 01:47am blood pt-12.0 ptt-24.6 inr(pt)-1.0 11:10am blood pt-13.7* ptt-41.1* inr(pt)-1.2* 10:05am blood pt-14.4* ptt-35.7* inr(pt)-1.2* 04:25am blood glucose-114* urean-34* creat-1.1 na-135 k-4.8 cl-96 hco3-26 angap-18 08:05am blood urean-36* creat-1.0 na-134 k-4.6 cl-97 brief hospital course: on mrs. was a same day admit after undergoing pre-operative work-up as an outpatient. on she was brought directly to the operating room where she underwent an aortic valve replacement. please see operative note for surgical details. following surgery she was transferred to the cvicu for invasive monitoring in stable condition. she awoke neurologically intact and was extubated without difficulty. she was weaned off pressor support and beta-blocker/aspririn/statin and diuresis were initiated. all lines and drains were discontinued in a timely fashion. she was transferred to the step down unit for further monitoring. pod#1 she went into atrial fibrillation and was treated with amiodarone and beta-blocker. she remained in rate controlled afib. anticoagulation was initiated with coumadin for atrial fibrillation. she was transferred to the step down unit for further monitoring. physical therapy was consulted for evaluation of strength and mobility. pod# 4 her rhythm paused for 5 and then 2.8 seconds. she was asymptomatic, sleeping, with hemodynamically stable blood pressure upon waking. beta-blocker and amiodarone were discontinued. electrophysiology was consulted for evaluation of nodal dysfunction. ms. complained of waking up with left knee pain that was edematous upon evaluation. rheumatology was consulted and a diagnostic/therapeutic aspiration was performed. she slowly progressed and on pod 7 she was cleared for discharge to rehabilitation. all follow up appointments were advised. medications on admission: eye gtts amlodipine 5mg daily fluticasone 50 mcg -
