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 (sulfonamides) attending: chief complaint: rare chest tightness major surgical or invasive procedure: ascending aorta replacement (34 mm gelweave) and aortic valve replacement (23mm ce pericardial tissue) history of present illness: 73 y/o with rare chest tightness. underwent follow-up echocardiogram which revealed an increasing ascending aortic anuerysm. past medical history: bipolar disorder, chronic urinary tract infections, s/p bilaeral varicose vein stripping, s/p cholecystectomy social history: retired. 15 cigs/d x 50 years (quit ). drinks etoh few times a month. family history: father with aortic aneurysm physical exam: preop: vs: 86 20 120/84 124/88 5'2" 175# skin: unremarkable heent: nc/at, eomi, perrl neck: supple, from, -jvd chest: ctab

right ventricular chamber size and free wall motion are normal. 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 moderately dilated. there are simple atheroma in the descending thoracic aorta. there are three aortic valve leaflets. there is no aortic valve stenosis. moderate (2+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. post-bypass: a bioprosthesis is well seated in the aortic position. all 3 leaflets move well. trace central ai is seen. a mean gradient of mm of hg is obtained. an ascending aortic graft is seen. lv function appears slightly improved and rv function is unchanged. cxr : 1. no significant change in left pleural effusion, which has a small loculated lateral component. 2. interval decrease in the right pleural effusion, and improved bibasilar aeration. 3. unusual orientation of sternotomy wires, with slight rightward displacement of uppermost wire. clinical correlation is recommended to exclude dehiscence. 12:33pm blood wbc-9.7 rbc-2.94*# hgb-9.3*# hct-27.1*# mcv-92 mch-31.6

the operating room where she underwent an aortic valve and ascending aorta replacement. please see operative note for surgical details. she tolerated the procedure well and was transferred to the csru for invasive monitoring in stable condition. later on op day she was weaned from sedation, awoke neurologically intact, and was extubated. on post-op day one her chest tubes were removed and she was transferred to the sdu. beta blockers and diuretics were initiated and she was gently diuresed towards her pre-op weight. on post-op day two her epicardial pacing wires were removed. she required additional o2 with aggressive pulmonary toilet until post-op day four. physical therapy worked with patient for strength and mobility. she recovered well without post-op complications and was discharged home with vna services and the appropriate follow-up appointments on post-op day seven. medications on admission: lamicatal 100" keflex 500 2x/wk for chronic uti trazadone 100@hs nicotine
