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: penicillins / egg attending: chief complaint: shortness of breath major surgical or invasive procedure: - aortic valve replacement(25mm mosaic porcine valve)/ascending aorta replacement (32mm gelweave graft)/coronary artery bypass graftingx1 (left internal mammary artery->left anterior descending artery). history of present illness: 83-year-old gentleman who has had increasing shortness of breath with occasional episodes of palpitations this past spring. he was hospitalized for heart failure in late and treated with diuretics. he admits to worsening shortness of breath and some lower extremity edema. ultimately this prompted echocardiogram and cardiac catheterization, which showed single-vessel coronary artery disease, aortic insufficiency and a dilated aorta. he was seen by dr. in for surgical management and presents today for preoperative testing. he is scheduled for surgery on which will be an ascending aorta replacement, aortic valve replacement and coronary artery bypass grafting versus a bental procedure with bypass grafting. past medical history: chronic diastolic heart failure aortic insufficiency aortic stenosis aortic aneurysm hypertension hypercholesterolemia childhood asthma peptic ulcer disease question of hepatitis c left lower extremity varicosities diverticular disease left bundle branch block severely hard of hearing in both ears bilateral hernia repair colectomy tonsillectomy bilateral cataract surgeries social history: he is currently retired. he quit smoking 40 years ago and had only a five-pack-year history. he does not use any alcohol. he lives with his wife of many years in ma. family history: non contriibutory physical exam: pulse: 56-60 irregular resp: 16 o2 sat: 98% ra b/p right: 128/48 left: 122/40 height: 70" weight: 140lbs general: thin somewhat frail appearing elderly gentleman in nad. skin: warm, dry, intact. bilateral lower extremity chronic venous stasis changes. heent: ncat, perrla, sclera anicteric, op benign. edentulous. neck: supple full rom , mild jvd chest: lungs clear bilaterally heart: sb->rrr with pvc's and skipped beats. iii/vi sem with a ii/vi diastolic murmur. abdomen:

bruit. pertinent results: echo pre bypass the left atrium is elongated. the left atrium is dilated. no spontaneous echo contrast or thrombus is seen in the body of the left atrium/left atrial appendage or the body of the right atrium/right atrial appendage. no atrial septal defect is seen by 2d or color doppler. left ventricular wall thicknesses are normal. the left ventricular cavity is moderately to severely dilated. there is moderate regional left ventricular systolic dysfunction with severe apical hypokinesis and mild global hypokinesis. overall left ventricular systolic function is moderately depressed (lvef= 35 %). right ventricular chamber size and free wall motion are normal. the aortic root is markedly dilated at the sinus level. the ascending aorta is markedly dilated. the aortic arch is mildly dilated. there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are complex (>4mm) atheroma in the descending thoracic aorta. the aortic valve leaflets (3) are mildly thickened but aortic stenosis is not present. severe (4+) aortic regurgitation is seen. the mitral valve leaflets are moderately thickened. the base of the posterior mitral leaflet is particularly thickened and calcified. mild (1+) mitral regurgitation is seen. there is a trivial/physiologic pericardial effusion. dr. was notified in person of the results in the operating room at the time of the study. post bypass the patient is being atrially paced. the patient is receiving epinephrine by infusion. there is normal right ventricular systolic function. the left ventricle displays moderate to severe apical hypokinesis with mild global left ventricular hypokinesis. ejection fraction is in the 35-40% range. there is a bioprosthesis in the aortic position. it appears well seated. initially, after separation from bypass, several jets of aortic regurgitation were seen. one appeared to be a trace to mild jet of paravalvular ai that transversed the left ventricular outflow tract. the other jets appeared to be trace and valvular in origin. 30 minutes later, only a single jet of trace ai was seen, it's origin not identifiable. the leaflets of the bioprosthesis are not seen. the effective valve area of the valve was about 2 cm2 with a peak gradient of 13 mmhg and a mean of 7 mmhg. the ascending aortic graft is seen only poorly in situ. the rest of the thoracic aorta apperas unchanged. mild mitral regurgitation persists. brief hospital course: admitted same day surgery and was brought to the operating room for ascending aorta replacement, aortic valve replacement and coronary artery bypass graft surgery. see operative report for further details. he received vancomycin for perioperative antibiotics. postoperatively he was transferred to the intensive care unit for hemodynamic management. in the first twenty four hours he was weaned from sedation, awoke neurologically intact, and was extubated without complications. he was progressively weaned off pressors on post operative day one. he developed atrial fibrillation which he was treated with beta blockers and amiodarone. on postoperative day two he converted to normal sinus rhythm, and was transferred to the postoperative floor. his chest tubes and temporary pacing wires were removed per protocol. physical therapy worked with him on strength and mobility. he was cleared for discharge to home with his family and 24 hr care which was already in place and vna services. of note mr. was discharged on 10meq of potassium supplement while he is not takin his lisinopril. once his lisinopril starts, he may need the potassium stopped. medications on admission: lisinopril 5 mg daily simvastatin 20 mg daily omeprazole 20 mg twice a day furosemide 80 mg twice a
