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: fatigue major surgical or invasive procedure: : aortic valve replacement with 21-mm biocor tissue valve. history of present illness: 80 year old female known to our service with known aortic stenosis and increasing gradients. she reports fatigue but is still able to work 6 days per week at a bakery. she denies shortness of breath or chest pain. she is quite active, however, walking is limited by arthritis. cath revealed no obstructive coronary lesions. she was referred for surgical evaluation and presents today for pre-operative testing. past medical history: aortic stenosis mitral regurgitation hypertension hyperlipidemia osteopenia vitamin d deficiency parathyroid tumor excision of left parotid tumor tonsillectomy social history: lives with: children and grand-children live in her home occupation: works 6days/week at market basket bakery, enjoys staying active tobacco: none etoh: none family history: father had cad, died at 68yo daughter and 2 sons all s/p mi with stents 3 sisters with hypertension physical exam: height: 63" weight: 162lb general: nad, wgwn, appears younger than stated age skin: dry intact heent: perrla eomi neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur 4/6 systolic with + thrill abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema: trace varicosities: moderate varicosities neuro: grossly intact pulses: femoral right: 2+ left:2+ dp right: np left:np pt : 2+ left:2+ radial right: 2+ left:2+ carotid bruit right/left: radiation of cardiac murmur pertinent results: echocardiography report left ventricle - ejection fraction: 55% >= 55% aorta - sinus level: 3.2 cm <= 3.6 cm aorta - ascending: 3.4 cm <= 3.4 cm aortic valve - lvot diam: 2.0 cm findings tee probe cannot be passed into the stomach. there was resistance and after a couple of tries no attempts were made to pass the tee probe beyond the me windows. the og tube did pass beyond oropharynx and also showed similar inability to pass it completely before tee was attempted. there was no specific history from the patient when asked for it in the preoperative holding area. dr. was conveyed of this issue. left atrium: la not well visualized. good (>20 cm/s) laa ejection velocity. right atrium/interatrial septum: normal ra size. no asd by 2d or color doppler. left ventricle: mild symmetric lvh with normal cavity size and regional/global systolic function (lvef>55%). suboptimal technical quality, a focal lv wall motion abnormality cannot be fully excluded. right ventricle: normal rv chamber size and free wall motion. aorta: normal aortic diameter at the sinus level. focal calcifications in aortic root. normal ascending aorta diameter. focal calcifications in ascending aorta. normal aortic arch diameter. normal descending aorta diameter. simple atheroma in descending aorta. aortic valve: severely thickened/deformed aortic valve leaflets. severe as (area 0.8-1.0cm2). mild (1+) ar. mitral valve: moderately thickened mitral valve leaflets. mild (1+) mr. tricuspid valve: normal tricuspid valve leaflets with trivial tr. pulmonic valve/pulmonary artery: normal pulmonic valve leaflet. no ps. physiologic pr. pericardium: no pericardial effusion. conclusions pre-bypass: no atrial septal defect is seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy with normal cavity size and regional/global systolic function (lvef>55%). due to suboptimal technical quality, a focal wall motion abnormality cannot be fully excluded. right ventricular chamber size and free wall motion are normal. there are simple atheroma in the descending thoracic aorta. the aortic valve leaflets are severely thickened/deformed. there is severe aortic valve stenosis (valve area 0.8-1.0cm2). mild (1+) aortic regurgitation is seen. no doppler measurements could be done due to lack of transgastric views. the mitral valve leaflets are moderately thickened. mild (1+) mitral regurgitation is seen. there is no pericardial effusion. post-bypass: normal biventricular systolic function. lvef 55%. intact thoracic aorta. 04:35am blood wbc-8.2 rbc-3.34* hgb-9.8* hct-28.6* mcv-86 mch-29.3 mchc-34.3 rdw-13.7 plt ct-182 10:22am blood wbc-8.3# rbc-2.73*# hgb-8.3*# hct-24.0*# mcv-88 mch-30.3 mchc-34.5 rdw-13.9 plt ct-96* 04:35am blood plt ct-182 10:22am blood plt ct-96* 10:22am blood pt-14.9* ptt-31.7 inr(pt)-1.3* 04:35am blood urean-20 creat-0.5 na-136 k-4.4 cl-98 11:35am blood urean-16 creat-0.5 na-144 k-3.7 cl-117* hco3-19* angap-12 02:12am blood calcium-8.2* phos-3.7 mg-2.0 04:35am blood mg-2.1 1. improved lung aeration -
