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: morphine attending: chief complaint: syncope major surgical or invasive procedure: redo-sternotomy, aortic valve replacement (23mm st. epic bioprosthetic) cardiac catheterization history of present illness: 81 year old male that presents with two recent syncopal episodes & loss of conciousness 5 days ago in context of progressive fatigue and dyspnea on exertion but without chest pain. evaluated at and was ruled-out for myocardial infacrtion or stroke. he has known coronary artery disease and is s/p cabg , as well as aortic stenosis ( 0.5cm on echo ). he was transferred from to be evaluated for an aortic valve replacement. past medical history: 1. cad s/p cabg, cabg () 2. hypercholesteremia 3. htn 4. aortic stenosis (dx in ) social history: - lives with wife. married for 53 years, 2 daughters and 1 - retired farmer (grew tomatoes) - denies smoking and alcohol family history: non-contributory physical exam: pulse: 73 sr resp: 16 o2 sat: 98/ra b/p:

na-136 k-3.7 cl-102 hco3-28 a mg-2.4 chest pa and lateral: there are small bilateral pleural effusions. again noted is a tortuous aorta and the sternotomy wires, which are stable. the cardiac, mediastinal and hilar contours are unremarkable. intraop tee: pre-bypass: 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. no atrial septal defect is seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef>55%). right ventricular chamber size and free wall motion are normal. the ascending aorta is mildly dilated. there are simple atheroma in the aortic arch. there are simple atheroma in the descending thoracic aorta as well as a 0.6 cm complex atheroma. the aortic valve leaflets are severely thickened/deformed. there is critical aortic valve stenosis (valve area <0.8cm2). mild (1+) aortic regurgitation is seen. a proper annular diameter is difficult to measure in face of heavy calcification. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. there is no pericardial effusion. post-bypass: the patient is receiving no inotropy support post-bypass. there is a well seated bioprosthetic valve in the aortic position. there is no aortic perivalvular or valvular leak. there is no evidence of lvot obstruction. the mean gradient across the aortic valve is 8 mmhg. biventricular function is preserved post-bypass at >55% ef. all other findings are similar to prebypass findings. the aorta is intact post-decannulation. findings were discussed in person with surgeon. brief hospital course: transferred from outside hospital for evaluation due to syncope. underwent cardiac catheterization that revealed no obstructive coronary disease with a widely patent left internal mammary artery to left anterior descending artery. surgery was consulted for aortic valve replacement and he underwent preoperative workup and monitoring of creatinine which increased from admission 1.4 to 1.7 on preoperatively. on he was brought to the operating room and underwent redo sternotomy, and aortic valve replacement. see operative report for further details. given he was in the hosptial for greater than 24 hours preoperatively, he received vancomycin for perioperative antibiotics. postoperatively he was transferred to the intensive care unit for management. in the first twenty four hours he was weaned from sedation, awoke neurologically intact and was extubated without complications. his cvicu course was otherwise uneventful, and on postoperative day two, he transferred to the sdu. he remained in a normal sinus rhythm as beta blockade was advanced as tolerated. postoperatively, his renal function remained stable. over several days, he continued to make clinical improvements with diuresis and he was ready for discharge to home on post operative day five. medications on admission: amlodipine 5mg daily aspirin 81 mg daily atenolol 25mg cilostazol 50mg fexofenadine () 60mg rosuvastatin 40mg daily hctz 25mg
