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: history of present illness: three weeks ago during a routine physical she mentioned to her doctor that she had been getting short of breath when she bends over to pick something up. she denied chest pain and was referred for an echocardiogram. the echocardiogram was done on . at that time it revealed critical aortic stenosis with an aortic valve area of 0.23 cm squared and a peak gradient of 122 mm/hg with a mean gradient of 67 mm/hg. there was 1+ aortic regurgitation and 2+ mitral regurgitation with concentric left ventricular hypertrophy. she was then referred to for cardiac catheterization. past medical history: significant for hypertension, hypercholesterolemia, cerebrovascular accident in with no residual weakness, right knee surgery and an appendectomy. the patient denies diabetes, any family history of cardiac disease, any transient ischemic attacks, any melena or gastrointestinal bleeds, any orthopnea, edema or paroxysmal nocturnal dyspnea, any lightheadedness or claudication. allergies: she has no known allergies. medications prior to admission: include: 1. atenolol 50 mg q. day. 2. imdur 30 mg q. day. 3. hydrochlorothiazide 25 mg q. day. 4. lisinopril 20 mg q. day. 5. lipitor 10 mg q. day. 6. aspirin 81 mg q. day. 7. clindamycin 300 mg t.i.d. due to recent dental cleaning. social history: she lives alone and is independent. laboratory data: white count 6, hematocrit 39.4, platelet count 188,000. sodium 134, potassium 3.5, chloride 93, co2 29, bun 13, creatinine 0.7, inr 1. physical examination: height 5'1", weight 116 pounds. vital signs: heart rate 64 sinus rhythm, blood pressure 160/48, respiratory rate 12, oxygen saturation 99% on room air. heent: pupils equal, round and reactive to light. positive arcus nose xanthoma. neck is supple. no carotid bruits. jugular venous distention to 9. respiratory: breath sounds clear to auscultation bilaterally. cardiac: regular rate and rhythm with a 2/6 systolic ejection murmur heard best at the left sternal border. abdomen is soft and non-tender, non-distended with seborrhea. extremities: no edema. varicosities. dorsalis pedis on the right 1+, posterior tibial 2+, dorsalis pedis on the left 1+, posterior tibial 2+. electrocardiogram: sinus rhythm, intervals 20, 0840, normal axis with left ventricular hypertrophy. cardiac catheterization: showed an aortic valve area of 0.38 cm squared with a peak gradient of 100 mm/hg, an index of 1.9 and a wedge of 22, pa pressures of 66/22 with a mean of 40. shared left main 20%, lad 60%, left circumflex with minimal irregularities and rca 90%. following catheterization, cardiothoracic surgery was consulted, the patient was seen and accepted for aortic valve replacement and coronary artery bypass grafting. while awaiting surgery, the patient was seen by the dental service who extracted an infected tooth prior to her surgery. on the patient was brought to the operating room. please see the operating room report for full details. in summary, the patient had an aortic valve replacement with a #19 mosaic valve and coronary artery bypass grafting times two with the left internal mammary artery to the left anterior descending artery and a saphenous vein graft to the right coronary artery. the surgery was complicated by an aortic tear which was repaired. the patient's bypass time was 137 minutes. her crossclamp time was 126 minutes. she was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer the patient had neo-synephrine at 1.5 mcg/kg/min, propofol at 20 mcg/kg/min and aprotinin at 25 cc/hour. the patient did well in the immediate postoperative period. her anesthesia was reversed, sedation was discontinued and she was weaned from the ventilator and successfully extubated. she was weaned from all cardioactive intravenous medications. on the morning of postoperative day one the patient remained hemodynamically stable, however, neurologically, she was alert and oriented only times one. at that time she could identify that she was in the hospital, however, she believed that she was in the . other than that she followed commands. her pupils were equally round and reactive to light and she had bilaterally equal motor strength. on postoperative day two the patient was begun on captopril, lopressor and intravenous nitroglycerin to control her blood pressure. she was also kept in the intensive care unit because of the need for vigorous pulmonary toilet and to monitor her neurological status. the patient continued to do well. her intravenous nitroglycerin was weaned to off. as her p.o. medications were increased she remained mildly confused and on postoperative day four she was transferred to the floor for continuing postoperative care and cardiac rehabilitation. for the next several days the patient continued to progress slowly in her activity level. she remained pleasantly confused. on postoperative day six neurology consult was called and the patient went for a head ct scan. ct scan showed no acute hemorrhage, no mass effect or shifts. two foci of the hypothalamus in the right parietal lobe that represented a probable prior infarction. neurology consult recommended working up any possible infectious processes that could exacerbate mental status changes and to hold all sedatives. on postoperative day eight it was decided that the patient was stable and ready for transfer to a rehabilitation facility for continuing postoperative care and rehabilitation. at the time of anticipated transfer, the patient's physical examination is as follows: vital signs: temperature 97.0, heart rate 71 sinus rhythm, blood pressure 126/54, respiratory rate 18, oxygen saturation 93% on room air. weight preoperatively 53 kilograms, at discharge 58 kilograms. laboratory data: white count 8.9, hematocrit 35, platelet count 144,000. sodium 137, potassium 3.9, chloride 102, co2 27, bun 20, creatinine 0.6, glucose 115. physical examination: awake, oriented times one, confused about place and time. conversant, moves all extremities. respiratory: clear to auscultation bilaterally. cardiac: regular rate and rhythm. s1, s2. sternum: stable incision with steri-strips, open to air, clean and dry. abdomen soft, non-tender, non-distended with positive bowel sounds. extremities are warm and well perfused. no clubbing, cyanosis or edema. left lower extremity incision with steri-strips. a dry sterile dressing at the top pole of the incision with a small amount of serous drainage. discharge medications: include: 1. pantoprazole 40 mg q. day. 2. captopril 75 mg t.i.d. 3. metoprolol 100 mg b.i.d. 4. enteric coated aspirin 325 mg q. day. 5. colace 100 mg b.i.d. 6. percocet 5/325 one to two tabs q. 4h. p.r.n. discharge diagnoses: include: 1. aortic stenosis status post aortic valve replacement with a #19 mosaic valve. 2. coronary artery disease status post coronary artery bypass grafting times two with left internal mammary artery to left anterior descending artery and saphenous vein graft to right coronary artery. 3. hypercholesterolemia. 4. hypertension. 5. status post cerebrovascular accident in . 6. status post right knee surgery. 7. status post appendectomy. condition at discharge: stable. disposition: to rehabilitation. follow up: primary care physician two to three weeks after discharge from rehabilitation and follow up with dr. four weeks from discharge at . , m.d. dictated by: medquist36 procedure: single internal mammary-coronary artery bypass extracorporeal circulation auxiliary
