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: no known allergies / adverse drug reactions attending: chief complaint: ascending aortic aneurysm, bicuspid aortic valve major surgical or invasive procedure: bental(27mm /28mm gelweave graft) history of present illness: this 59 year old male with a known ascending aneruysm for at least 7 years, followed by serial echocardiograms. his last echo revealed a 5cm dilated root with a probable bicuspid valve and moderate aortic insufficiency. he had a negative stress echo and catheterization revealed no significant coronary disease. he was admitted for elective surgery. past medical history: thoracic ascending aneurysm depression vertigo paroxysmal atrial fibrillation social history: self employed/actor 20pk year history, stopped bottle of wine /week demntal exam <6 months family history: father had aneurysm sx in his 80s(? type) physical exam: hr 54 bp 122/75 rr 18 sat 99% physical exam- general: wdwn in nad cardiac: rrr with quiet diastolic murmur chest: lungs clear bilateral abdomen: soft nontender nondistended extremities: warm well perfused edema: none pertinent results: day of surgery: 05:19pm blood wbc-12.3*# rbc-2.86*# hgb-9.1*# hct-25.5*# mcv-89 mch-31.8 mchc-35.6* rdw-12.9 plt ct-132* 05:19pm blood pt-15.3* ptt-33.8 inr(pt)-1.3* 05:19pm blood fibrino-167 10:16pm blood urean-13 creat-1.1 na-145 k-4.0 cl-106 hco3-28 angap-15 day of discharge: 04:45am blood wbc-9.5 rbc-4.15* hgb-12.4* hct-36.5* mcv-88 mch-29.8 mchc-33.9 rdw-13.8 plt ct-199 04:45am blood plt ct-199 04:45am blood glucose-117* urean-47* creat-1.2 na-137 k-4.1 cl-102 hco3-23 angap-16 radiology report chest (pa & lat) study date of 2:25 pm chest two views on findings: the right ij line has been removed. there is dense retrocardiac opacification consistent with volume loss/infiltrate. there is also small left effusion, small right effusion. the upper lungs are clear. compared to the study from three days ago the lung aeration is improved. dr. echocardiography report echocardiographic measurements results measurements normal range left ventricle - ejection fraction: 55% to 65% >= 55% aorta - ascending: *4.9 cm <= 3.4 cm aortic valve - lvot diam: 2.2 cm findings left atrium: normal la size. good (>20 cm/s) laa ejection velocity. no thrombus in the laa. right atrium/interatrial septum: normal ra size. left ventricle: normal lv wall thickness. normal lv cavity size. right ventricle: normal rv chamber size and free wall motion. aorta: mildy dilated aortic root. moderately dilated ascending aorta mildly dilated aortic arch. normal descending aorta diameter. aortic valve: bicuspid aortic valve. no as. moderate to severe (3+) ar. mitral valve: normal mitral valve leaflets with trivial mr. tricuspid valve: normal tricuspid valve leaflets with trivial tr. pulmonic valve/pulmonary artery: normal pulmonic valve leaflet. no ps. physiologic pr. pericardium: no pericardial effusion. general comments: a tee was performed in the location listed above. i certify i was present in compliance with hcfa regulations. the patient was under general anesthesia throughout the procedure. the patient received antibiotic prophylaxis. the tee probe was passed with assistance from the anesthesioology staff using a laryngoscope. no tee related complications. patient. regional left ventricular wall motion: n = normal, h = hypokinetic, a = akinetic, d = dyskinetic conclusions pre-cpb: 1. the left atrium is normal in size. no thrombus is seen in the left atrial appendage. 2. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. 3. right ventricular chamber size and free wall motion are normal. 4. the aortic root is mildly dilated at the sinus level. the ascending aorta is moderately dilated. the aortic arch is mildly dilated. 5. the aortic valve is bicuspid. there is no aortic valve stenosis. moderate to severe (3+) aortic regurgitation is seen. 6. the mitral valve appears structurally normal with trivial mitral regurgitation. 7. there is no pericardial effusion. dr. was notified in person of the results. post-cpb: on infusion of nitroglycerine, av pacing for slow sr with 1 degree av block. pt placed on cpb x 3 for bleeding, dehiscence of aortic valve. well-seated bioprosthetic valve in the aortic position. trace ai. trivial systolic gradient with co= 5 l/min. small pericardial efusion. aortic contour in the descending arch is normal post decannulation. i certify that i was present for this procedure in compliance with hcfa regulations. electronically signed by , md, interpreting physician 21:38 brief hospital course: this patient is a same day admission, he was taken to the operating room where a bental procedure was performed. the valve was indeed bicuspid. at the end of the case he had significant bleeding from the right coronary button which required reopening of the chest, the bleeding was then controlled surgically. he required multiple blood products to correct a coagulopathy but stabilized and was brought to the cardiac surgery icu in stable condition. he was relatively hypoxic post-operatively likely from the volume of blood products he received. he was kept sedated and aggressively diuresed over the next several days. he awoke neurologically intact but cognitively slowed, he was weaned from the ventilator and extubated on pod 3. he continued to be diuresed, beta blockade was begun and he was seen by physical therapy to assist with mobility and endurance. he remained in the icu to monitor his pulmonary status. all tubes, lines and drains were removed per cardiac surgery protocols. on pod5 he transferred to the step down floor. over the next several days he worked with physical therapy and nursing to improve his conditioning and allow his cognitive status to improve. by pod8 he was ready for discharge home with a visiting nurse. followup in 1 week for wound check and 4 weeks with dr medications on admission: medications -
