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: this is a 44-year-old female with a past medical history of migraine headaches. on she was walking down the stairs and had sudden onset of total blackout of vision in her right eye. she thought it was a migraine and took nonsteroidals and noticed her right face and arm felt heavy. there was no facial droop, slurred speech, or weakness. she laid down and her vision improved, but it was fractured. she went to bed and the next morning her vision was unchanged, but her face and arm felt better. she went to her primary care doctor where she had an mri which was read as showing an old migraine, but otherwise was fine. she saw a retinal specialist who saw a retinal artery occlusion and made a diagnosis of central retinal artery occlusion with visualization of calcium embolus. she had a transthoracic echocardiogram which revealed a bicuspid valve. her vision steadily improved, but a week later she had 20 minutes of confusion while in a restaurant and worsening of her vision. she was admitted to and then transferred to . she had another mri of the head and neck which showed no acute process except for chronic punctate left frontal lobe lacunar or old inflammatory process of the subcortical white matter. she had a hypercoagulable work-up which was all negative. she also had a transthoracic echocardiogram. this showed her aortic valve had a peak gradient of 51 mmhg and an aortic valve area of 1.1 cm sq. a transesophageal echocardiogram showed no plaque or clot and that her ejection fraction was 55%. she was anticoagulated and discharged to home on lovenox to return for surgery. she is admitted now for aortic valve replacement. past medical history: 1. history of migraines. 2. history of anxiety attacks. allergies: the patient is allergic to contrast dye and morphine. medications: she was on lovenox on admission. social history: she lives with her husband and four children. she does not smoke cigarettes. she drinks three to four glasses of red wine per week. family history: unremarkable. review of systems: as above. physical examination: she was a well-developed, well-nourished white female in no apparent distress. vital signs were stable, afebrile. heent: normocephalic, atraumatic, extraocular movements intact. oropharynx benign. neck: supple, full range of motion, no lymphadenopathy or thyromegaly. carotids 2+ and equal bilaterally without bruits. lungs: clear to auscultation and percussion. cardiovascular: regular rate and rhythm, normal s1 and s2, with no murmurs, gallops, or rubs. abdomen: soft, nontender with positive bowel sounds; no masses or hepatosplenomegaly. extremities: without cyanosis, clubbing or edema. neurological: examination was nonfocal. pulses: 2+ and equal bilaterally throughout. hospital course: on she underwent an aortic valve replacement with a . supra-annular aortic mechanical valve and a 20 mm gelweave graft supracoronary aortic ascending graft. her crossclamp time was 119 minutes. total bypass time 155 minutes. circulatory arrest time was nine minutes. she was transferred to the cardiac surgery recovery unit on neo-synephrine and propofol. she had a stable postoperative night and was extubated. she did require a large amount of volume her postoperative night, and was very edematous on her first few postoperative days. on postoperative day one she was begun on diuresis. on postoperative day two her chest tubes were discontinued. on postoperative day three she was transferred to the floor in stable condition and had her epicardial pacing wires discontinued. she did have a large amount of incisional pain and had migraine headaches and had a lot of nausea and difficulty with p.o. intake. she was treated with ibuprofen, dilaudid, reglan, zofran, and ativan. she continued to slowly progress and was seen by neurology who felt these were tension headaches and migraines and switched her from a beta blocker to calcium channel blocker. she slowly improved. she also was being anticoagulated with coumadin and heparin and was slow to have her inr become therapeutic. on postoperative day number 11 she was discharged to home in stable condition. her laboratory studies on discharge were white count 8,800, hematocrit 26.6, platelet count 278,000, sodium 137, potassium 4.4, chloride 101, co2 28, bun 12, creatinine 0.6, blood sugar 97, patient 17.2 with an inr of 2. discharge medications: 1. lasix 20 mg p.o. b.i.d. x 7 days. 2. coumadin 7.5 mg alternating with 10.5 mg p.o. q.o.d. 3. colace 100 mg p.o. b.i.d. 4. dilaudid ?????? to 1 p.o. q. 4-6 hours p.r.n. pain. 5. ibuprofen 800 mg p.o. q. 4-6 hours. 6. potassium 20 meq p.o. b.i.d. x 7 days. 7. verapamil 180 mg p.o. q.d. fop plans: she will be followed by dr. in one to two weeks and by dr. on , and by dr. in four weeks. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart open and other replacement of aortic valve resection of vessel with replacement, thoracic vessels monitoring of cardiac output by other technique diagnoses: thoracic aneurysm without mention of rupture aortic valve disorders congenital insufficiency of aortic valve other forms of migraine, without mention of intractable migraine without mention of status migrainosus central retinal artery occlusion 

Answer: The patient is high likely exposed to
