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: patient recorded as having no known allergies to drugs attending: chief complaint: syncope major surgical or invasive procedure: aortic valve replacement utilizing a 27mm ce perimount pericardial tissue valve history of present illness: this is a 48 year old male who was admitted to outside hospital after syncopal episode. noted to be in rapid atrial fibrillation at that time and converted back to a normal sinus rhythm with lopressor and intravenous cardizem. echocardiogram revealed bicuspid aortic valve with severe critical aortic stenosis. the aortic valve area was estimated at 0.6cm2. his left ventricular ejection fraction was 55-60%. cardiac catheterization on confirmed severe aortic stenosis. coronary angiography revealed clean coronary arteries. based on the above results, he was transferred to the for cardiac surgical intervention. past medical history: aortic stenosis, childhood heart murmur, history of atrial fibrillation, history of migraine headaches, horseshoe kidney social history: denies tobacco and excessive etoh. married with children. works in construction. currently lives with his wife. family history: uncle died suddenly at young age(before 55). physical exam: vitals: bp 110/84, hr 71, rr 16, sat 96% on room air general: well developed male in no acute distress heent: oropharynx benign, left temporal ecchymosis, stitches noted below lower lip neck: supple, no jvd, heart: regular rate, normal s1s2, 4/6 systolic ejectiom murmur which radiated to carotid region lungs: clear bilaterally abdomen: soft, nontender, normoactive bowel sounds ext: warm, no edema, varicosities noted on left leg pulses: 2+ distally neuro: alert and oriented, nonfocal pertinent results: 04:40pm glucose-94 urea n-15 creat-1.0 sodium-142

48 year old man s/p avr reason for this examination: evaluate pneumothorax and atx indication: 48-year-old man status post aortic valve replacement. pa and lateral chest x-ray dated is compared to the prior from yesterday. the patient is status post median sternotomy. the aortic valve has been replaced. there is stable elevation of the left hemidiaphragm with left lower lobe atelectasis and pleural effusion. there is no evidence for congestive heart failure or pneumothorax. impression: stable elevation of left hemidiaphragm with a small left pleural effusion. no pneumothorax. the study and the report were reviewed by the staff radiologist. dr. . dr. general comments: a tee was performed in the location listed above. i certify i was present in compliance with hcfa regulations. no tee related complications. the patient was under general anesthesia throughout the procedure. the patient appears to be in sinus rhythm. results were personally post-bypass data conclusions: pre-bypass: 1. overall left ventricular systolic function is normal (lvef>55%). regional left ventricular wall motion is normal. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. 2. there is moderate aortic valve stenosis. the aortic valve is bicuspid. the aortic valve leaflets are severely thickened/deformed. no aortic regurgitation is seen. 3. the left atrium is moderately dilated. no atrial septal defect is seen by 2d or color doppler. 4. right ventricular chamber size and free wall motion are normal. 5. the mitral valve leaflets are structurally normal. trivial mitral regurgitation is seen. 6. there is a trivial/physiologic pericardial effusion. post-bypass: 1. a well-seated bioprosthetic valve is seen in the aorticl position with normal leaflet motion and gradients (mean gradient = 13 mmhg). no perivalvular leak is seen. trace aortic regurgitation is seen. 2. regional and global biventricular systolic function are normal. 3. no aortic dissection is seen post decannulation. 4. rest of study is unchanged from pre-bypass study. physician: brief hospital course: mr. was admitted and underwent routine preoperative evaluation. an echocardiogram confirmed a bicuspid aortic valve with severe aortic stenosis. a carotid ultrasound showed normal internal carotid arteries. he was cleared by the dental service after bedside and radiographic examinations. he otherwise remained stable on medical therapy and was cleared for surgery. no further episodes of atrial fibrillation were noted on telemetry after cardioversion. on , dr. performed an aortic valve replacement. surgery was uncomplicated and he was brought to the csru for invasive monitoring. for further surgical details, please see seperate dictated operative note. within 24 hours, he awoke neurologically intact and was extubated without incident. low dose beta blockade was resumed and amiodarone was initiated for ventricular ectopy. he otherwise maintained stable hemodynamics and transferred to the sdu on postoperative day one. he was gently diuresed and physical therapy initiated. he continued to progress without complications and was discharged home on post operative day 5 in good condition with vna services. medications on admission: aspirin 325 qd, protonix 40 qd, zocor 20 qd, toprol xl 50 qd, ativan prn discharge medications: 1. docusate
