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: sulfa (sulfonamide antibiotics) attending: chief complaint: dyspnea on exertion/diminished exercise tolerance/ intermittent angina major surgical or invasive procedure: aortic valve replacement (19mm st. juse tisse), coronary artery bypass graft x 1 (saphenous vein graft to obtuse marginal) history of present illness: 75 year old female with a history of aortic stenosis which has been followed by serial echocardiograms. recently she has become symptomatic with a markedly diminished exercie tolerance and dyspnea on exertion which were new symptoms. an echocardiogram was obtained which showed severe aortic stenosis with an increased mean gradient. a stress test earlier in the year showed poor exercise tolerance with slight st depressions. in preparation for surgery, a cardiac catheterization was obtained which showed a 60% circumflex stenosis. given the progression of her disease and symptoms, she has now been referred for aortic valve replacement and surgical revascularization. past medical history: aortic stenosis s/p aortic valve replacement coronary artery disease s/p coronary artery bypass graft x 1 hypertension hyperlipidemia

echo: pre-bypass: the left atrium is mildly dilated. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. right ventricular chamber size and free wall motion are normal. 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. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. there is no pericardial effusion. post cpb: 1. preserved -vewntricular systolic function. 2. prosthetic valve identified in aortic position. it is well sr\eated and stable. normal lealfet motion. there is mild perivalvular reguragitation. unable to obtain gradients across the aortic valve due to poor transgastric windows. 3. no other change.

the operating room where she underwent an aortic valve replacement and coronary artery bypass graft x please see operative note for surgical details. following surgery she was transferred to the cvicu for invasive monitoring in stable condition. she initially woke with some right sided neglect which resolved on pod1 with no residual focal deficits. she was agitated initially post op and self extubated on pod1. all narcotics were discontinued for lethargy and zyprexa was given once for delirium. her mental status slowly improved over the next several days and she was neurologically intact at the time of discharge. on pod 2 chest tubes were removed with some bleeding at chest tube sites requiring sutures in the right and middle site with resolution of the bleeding. on pod 3 she went into rapid atrial fibrillation with subsequent hypotension and was briefly started on neosynephrine and converted to sinus rhythm on an amiodarone drip. she was given a unit of blood for a hematocrit of 23 and weaned off pressors. afib resumed and she was placed on coumadin. on pod 4 the patient had an episode of amaurosis fugax of the right eye. this was associated with right temporal headache and jaw claudication. additionally, esr and crp were elevated. she does have a history of temporal arteritis. rheumatology, ophthalmology and vascular surgery were consulted. high dose steroids were initiated. vascular surgery did not feel that temporal artery biopsy was warranted given the chronicity of her symptoms and that she's had a right sided temporal biopsy in the past. rheumatology feels strongly that the patient should be treated empirically, and that she may have been incompletely treated for her previous episode. she was placed on pcp prophylaxis in the setting of high dose steroids. visual symptoms resolved and the patient will follow up with her ophthalmologist, dr. as an outpatient. medications on admission: levothyroxine 112mcg daily pravastatin 40mg daily aspirin
