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: lipitor attending: chief complaint: dyspnea on exertion major surgical or invasive procedure: aortic valve replacement (23mm ce pericardial), coronary artery bypass graft x 1 (lima to lad) history of present illness: 69 y/o male with h/o atrial fibrillation, aortic stenosis, and coronary artery disease who is now having increased symptoms of dyspnea on exertion. along with fatigue and dizziness. he was referred for surgical intervention. past medical history: aortic stenosis, coronary artery disease, gastroesophageal reflux disease, atrial fibrillatoin s/p ablation, s/p ppm , erectile dysfunction s/p hernia repair, s/p bilat knee arthroscopy social history: denies tobacco or etoh use. family history: nc physical exam: vs: 72 18 154/98 6' 195# gen: wdwn

well-perfused -edema, -varicosities neuro: grossly intact, a&o x 3 pertinent results: echo: prebypass: 1. the left atrium is normal in size. no spontaneous echo contrast or thrombus is seen in the body of the left atrium or left atrial appendage. 2. left ventricular wall thicknesses and cavity size are normal. overall left ventricular systolic function is low normal (lvef 50-55%). right ventricular chamber size and free wall motion are normal. 3. the ascending and transverse thoracic aorta are normal in diameter and free of atherosclerotic plaque. there are simple atheroma in the descending thoracic aorta. 4. there are three aortic valve leaflets, which are moderately thickened. there is severe aortic valve stenosis (area <0.8cm2). 5. mild (1+) aortic regurgitation is seen. the mitral valve leaflets are moderately thickened. 6. there is no pericardial effusion. 7. dr. was notified in person of the results on at 1209. postbypass: 1. pt is currently on a phenylephrine infusion 2. the pt has thickened lv walls with an underfilled ventricle. wall motion is unchanged from prebypass, with ef 50% 3. the aortic annular ring can be seen well seated with no perivalvular leak. there is +1 aortic insufficiency 4. the contours of the aortic root are smooth after aortic cannular was removed. cxr: as compared to the previous radiograph, there is no relevant change. the monitoring and support devices are in unchanged position. there is no evidence of pneumothorax and no evidence of major pleural effusion. subtle retrocardiac atelectasis. no focal parenchymal opacities suggestive of pneumonia. mild overinflation of the stomach. 05:25pm blood wbc-6.3 rbc-5.04 hgb-15.7 hct-44.2 mcv-88 mch-31.2 mchc-35.6* rdw-13.5 plt ct-210 05:35am blood wbc-21.5*# rbc-4.63

brief hospital course: mr. was admitted a day before surgery d/t being on coumadin for h/o atrial fibrillation. he discontinued it 5 days before surgery. upon admission he was started on heparin and appropriately worked up for surgery. on he was brought to the operating room where he underwent a aortic valve replacement and coronary artery bypass graft x 1. please see operative report for surgical details. following surgery he was transferred to the cvicu for invasive monitoring in stable condition. later on op day he was weaned from sedation, awoke neurologically intact and extubated. on post-op day one ep was consulted to interrogate his pacemaker. later on this day mr. appeared to be doing well and was transferred to the telemetry floor for further care. mr was in chronic afib that was difficult to control and his metoprolol was advanced. he was re-started on coumadin on pod 2. a rub was noticed and he was started on ibuprofen.the remainder of his postoperative course was essentially unremarkable. due to an elevated wbc ct. blood and urine cultures were sent and empiric antibiotics were started. urine cx originally positive and sensitive to abx but repeat finalized negative. the wbc ct improved to normal and his temp.remained afebrile, at time of discharge blood cultures were pending, it was decided to continue a full week of antibiotic coverage. he was restared on his preoperative dose of digoxin, along with his preoperative coumadin regiment of 5 mg alt. with 2.5 mg daily, with vna. he was advised on all follow up appointments. medications on admission:
