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 attending: chief complaint: dyspnea on exertion major surgical or invasive procedure: aortic valve replacement (23mm ce pericardial tissue valve) history of present illness: 73 y/o female hospitalized in for congestive heart failure. improved with diuresis. work-up revealed severe aortic stenosis. past medical history: aortic stenosis, congestive heart failure, hypertension, hypercholesterolemia, diabetes mellitus, obesity, osteoarthritis, left cataract, hemorrhoids social history: denies tobacco and etoh use. family history: father died of cva at 55 brother with cad physical exam: vs: 70 12 114/72 62" 169# general: obese female in nad heent: eomi, perrla, nc/at neck: supple, from, -jvd lungs: ctab -w/r/r heart: rrr, 4/6 sem (murmur radiates to carotids) abd: soft, nt/nd, +bs ext: warm, well-perfused, -edema, -varicosities neuro: a&o x 3, mae, non-focal pertinent results: echo : pre-cpb: 1. the left atrium is normal in size. no spontaneous echo contrast is seen in the body of the right atrium or right atrial appendage. a left-to-right shunt across the interatrial septum is seen at rest. a small secundum atrial septal defect is present. 2. there is mild symmetric left ventricular hypertrophy with normal cavity size. 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%). transmitral doppler and tissue velocity imaging are consistent with grade i (mild) lv diastolic dysfunction. 3. right ventricular chamber size and free wall motion are normal. right ventricular chamber size is normal. right ventricular systolic function is normal. 4. there are simple atheroma in the aortic root. there are simple atheroma in the ascending aorta. there are simple atheroma in the aortic arch. there are simple atheroma in the descending thoracic aorta. 5. there are three aortic valve leaflets. the aortic valve leaflets are severely thickened/deformed. no masses or vegetations are seen on the aortic valve. there is severe aortic valve stenosis (area <0.8cm2). trace aortic regurgitation is seen. 6. the mitral valve leaflets are mildly thickened. no mass or vegetation is seen on the mitral valve. mild (1+) mitral regurgitation is seen. 7. there is no pericardial effusion. post-cpb: the bioprosthetic (#23 perimount) aortic valve is well seated without any paravalvular leak. no aortic regurgitation is seen. the lv systolic function is well preserved. the rv systolic function is also well preserved. there is no evidence of aortic dissection. brief hospital course: ms. was a same day admit after undergoing work-up as an outpatient. on she was brought to the operating room where she underwent a aortic valve replacement. please see operative report. following surgery she was transferred to the csru for invasive monitoring in stable condition. later on op day she was weaned from sedation, awoke neurologically intact and extubated. on post-op day one chest tubes were removed and diuretics and beta blockers were started. she was gently diuresed towards her pre-op weight. later this day she was transferred to the sdu. on post-op day three her epicardial pacing wires were removed. physical therapy worked with patient during hospital course for strength and mobility. she continued to improve other the next several days with adjustment in her medications and appeared ready for discharge home on post-op day ****. medications on admission: aspirin 325mg qd, lopressor 25mg qd, lasix 40mg qd, kcl 20 meq qd, zocor 10mg qd discharge disposition: home with service facility: discharge diagnosis: aortic stenosis s/p aortic valve replacement pmh: congestive heart failure, hypertension, hypercholesterolemia, diabetes mellitus, obesity, osteoarthritis, left cataract, hemorrhoids discharge condition: good discharge instructions: patient may shower, no baths. no creams, lotions or ointments to incisions. no driving for at least one month. no lifting more than 10 lbs for at least 10 weeks from the date of surgery. monitor wounds for signs of infection. please call with any concerns or questions. p instructions: dr. in 4 weeks dr.
