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: lisinopril attending: chief complaint: exertional chest pain major surgical or invasive procedure: aortic valve replacement utilizing a 23mm st. mechanical valve history of present illness: this is a 60 year old male with known aortic stenosis who recently has been complaining of worsening chest pain. there is no history of syncope or shortness of breath. a recent echocardiogram from confirmed severe aortic stenosis - valve area of 0.7cm2, peak 80 and mean of 47 mmhg. his lvef was normal with only 1+ mitral regurgitation. subsequent cardiac catheterization revealed severe aortic stenosis with a valve area of 0.7cm2. angiography showed only mild coronary artery disease with a 50% lesion in the left anterior descending artery. based on the above results, he was referred for cardiac surgical intervention. past medical history: aortic stenosis, mild coronary artery disease, hypertension, hypercholesterolemia, renal insufficiency, prior hernia repair, prior tonsillectomy, history of frequent epistaxis social history: quit tobacco over 30 years ago. denies excessive etoh. currently employed and works for trial court. he is married and lives with his wife. family history: father had mi in his late 40's physical exam: vitals: ******************* general: well developed male in no acute distress heent: oropharynx benign, perrl, eomi neck: supple, no jvd, transmitted murmur noted over carotids heart: regular rate, normal s1s2, 3/6 systolic ejection murmur lungs: clear bilaterally abdomen: soft, nontender, normoactive bowel sounds ext: warm, no edema, no varicosities pulses: 2+ distally neuro: alert and oriented, cn 2-12 intact, mae, nonfocal pertinent results: ct scan: bilateral perihilar and lower lobe opacities with associated pleural effusions consistent with moderate-to-severe pulmonary edema. no evidence of small-bowel obstruction. abdominal ultrasound: the gallbladder is mildly distended. there is no gallbladder wall thickening, pericholecystic fluid, or gallstones present. there is a small amount of gallbladder sludge. there is no intra- or extra- hepatic ductal dilatation. tee: overall left ventricular systolic function is mildly depressed. resting regional wall motion abnormalities include mildly hypokinetic anterior, anterior septum and anterior walls. a mechanical aortic valve prosthesis is present. mild (1+) aortic regurgitation is seen. cardiac cath: mild coronary artery disease. ct scan: low attenuation of the liver, most likely consistent with fatty infiltration. no evidence of cholecystitis but exam significantly limited secondary to lack of iv contrast administration. bilateral pleural effusions with associated atelectasis, not significantly changed compared to the previous study. mrcp: no intra- or extraheptic biliary ductal dilitation or pancreatic ductal dilatation. no biliary stones. no evidence of peripancreatic inflammation. brief hospital course: on the day of admission, mr. mechanical aortic valve replacement by dr. . for surgical details, please see separate dictated operative note. following the operation, he was brought to the csru for invasive monitoring. initially maintained on neo-synephrine and epinephrine for low cardiac indices. also required av pacing for complete heart block. within 24 hours, he awoke neurologically intact and was extubated on postoperative day one. on postoperative day two, he complained of mild abdominal pain associated with abdominal distention. an nasogastric tube was placed. general surgery was consulted and multiple imaging studies were obtained. ct scan was unremarkable except for pulmonary edema while abdominal ultrasound revealed only mild gallbladder distention with small amount of sludge. he concomitantly experienced worsening oxygenation and required reintubation on pod3. at that time, he was noted to have elevation in white count, creatinine, lactate, lfts, amylase, and lipase. lactate levels peaked to 5.3 on pod3. white count peaked to 15k on pod3. his creatinine peaked to 2.4 on pod5. he was empirically started on antibiotics for presumed pneumonia(serial chest x-rays showed worsening bilateral infiltrates). an echocardiogram showed no evidence of tamponade and repeat cardiac catheterization showed no obstructive coronary artery disease. given his mechanical aortic valve, patient required heparinization. he was kept sedated and intubated for several additional days. he was noted to have copious amounts of secretions which required frequent suctioning. therapeutic bronchoscopy was also performed. over these several days, his abdominal distention improved and his complete heart block resolved. he gradually weaned from inotropic support. his acidosis resolved and there was slow improvement in white count, lfts, amylase, lipase, and lactate. amylase peaked at 277 on pod9. lipase peaked to 1601 on pod8. alt peaked at 223 on pod5. ast peaked at 314 on pod2. total bilirubin peaked to 6.5 on pod6. he was intermittently was transfused with packed red blood cells to maintain hematocrit and he continued to make clinical improvements with diuresis. patient was re-extubated on pod6. general surgery continued to follow and recommended further imaging studies to evaluate for pancreatitis. an abdominal ct scan on was negative for pancreatitis. on , mr. developed epigastric tenderness and tpn was started. an mri of the abdomen was performed which showed no intra- or extrahepatic biliary ductal dilatation or pancreatic ductal dilatation, no biliary stones and no evidence of peripancreatic inflammation. a clear liquid diet was started and progressed towards a regular diet as tolerated. as he tolerated this well, he was transferred to the step down unit on for further recovery and discharge planning. physical therapy continued to work with him daily. mr. continued to make steady progress and was discharged home on postoperative day fourteen. he will follow-up with dr. , his cardiologist and his primary care physician as an outpatient. medications on admission: tricor 48 qd, atenolol 25 qd, aspirin 325 qd discharge medications: 1. aspirin 81 mg tablet, delayed
