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 / tramadol hcl / hydrocodone attending: chief complaint: dyspnea on exertion major surgical or invasive procedure: - avr (21mm mosaic ultra porcine valve) history of present illness: this is a female patient with a past medical history of aortic valve disease, followed over the years by dr. . she has been stable until recently. she was seen in an office visit on with complaints of worsening dyspnea on exertion and exercise induced chest pain. according to dr. ??????s note her most recent echocardiogram revealed an aortic valve area of 0.9 cm2. she was scheduled to undergo knee surgery but has postponed that for the time being. she is now admitted for surgical management of her aortic valve stenosis. in terms of symptoms, she reports a significant reduction in her functional capacity with dyspnea on minimal exertion. she states she has difficulty with minimal tasks. past medical history: hypertension hyperlipidemia aortic stenosis osteoarthritis pending bilateral knee replacements colectomy with colostomy and reversible for bowel obstruction social history: she is a widow with 5 grown children. she does smoke or drink. she is a homemaker. her son will bring her his family history: her brother recently had a cardiac stent in his 60??????s physical exam: 72 sr 18 155/72 gen: nad heent: perrl, eomi, anicteric sclera, op benign neck: supple, no jvd lungs: clear heart: rrr, iv/vi systolic murmur abd: soft, nontender, nondistended, normoactive bowel sounds ext: warm, well perfused, no edema neuro: nonfocal pertinent results: echo pre bypass no spontaneous echo contrast or thrombus is seen in the body of the left atrium/left atrial appendage or the body of the right atrium/right atrial appendage. no atrial septal defect is seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity is small. 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 right ventricular free wall is hypertrophied. the ascending aorta is mildly dilated. there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. there are three aortic valve leaflets. the aortic valve leaflets are severely thickened/deformed. there is severe aortic valve stenosis (area <0.8cm2). moderate (2+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild (1+) mitral regurgitation is seen. there is a small pericardial effusion. dr. was notified in person of the results in the operating room at the time of the study. post bypass normal biventricular systolic function. there is a bioprosthesis located in the aortic position. it appears well seated. the leaflets can not be seen. no aortic regurgitation is seen. the maximum pressure gradient across the aortic valve is 47 mm hg with a mean gradient of 20 mm hg at a cardiac output of 4.23 l/m. the effective orifice area of the valve is around 1 cm2. the gradients are a little higher and the area a little smaller than is expected for this prosthesis. the rest of the exam is unchanged from the pre-bypass study. the thoracic aorta appears intact. 04:14am blood wbc-17.3* rbc-3.20* hgb-8.9*

angap-15 brief hospital course: ms. was admitted to the on for surgical management of her aortic valve stenosis. she was taken directly to the operating room where she underwent and aortic valve replacement using a tissue valve. please see operative note for details. postoperatively she was taken to the intensive care unit for monitoring. on pod#1 she was extubated and noted to be lethargic with left sided weakness. she required re-intubation after 3 hours due to fatigue. she had a short burst of atrial fibrillation, but was hemodynamically stable and did not require intervention. on pod#2 a head ct scan was negative for an acute neurologic event. neurology was consulted and thought the patient may have had small frontal infarct that was not evident on ct scan. an mri revealed no acute abnormality. a temporary nasogastric feeding tube was placed for nutrition. diureses was ongoing to facilitate extubation. she was able to successfully wean and extubated on pod #5. her neurologic status slowly improved over the ensuing days and her left upper extremity strength improved but did not fully return to baseline. she was evaluated by physical therapy and rehab was recommended. she completed a course of ciprofloxacin for a urinary tract infection. her beta blockade was stopped for bradycardia. the bradycardia abated after the lopressor was discontinued. by post-operative day fourteen she was ready for discharge to rehab. medications on admission: brimonadine , clonidine 0.1", diltiazem 240', cosopt , folic acid 1', hctz 12.5', cellcept ", vit c 250',
