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: history of present illness: this is a 45-year-old male with known murmur x20 years. echo showed severe mitral regurgitation. he was then referred for cardiac catheterization. catheterization was done on that showed normal coronary arteries with severe mitral regurgitation and normal ventricular function, and an ef (ejection fraction) of 61. past medical history: is significant only for remote prostatitis. medications: at the time of admission include ativan p.r.n. vitamins and aspirin 81 mg q.daily. he states an allergy to penicillin, which causes a rash. social history: he lives with his wife and two children. he denies tobacco use, social alcohol use, 1 to 2 drinks per week. family history: mother had an mi (myocardial infarction) in the past. review of systems: noncontributory. physical examination: vital signs: pulse 76, blood pressure 148/80, respiratory rate 20, height 6 feet 1 inch, weight 185 pounds. general: well-appearing 45-year-old man in no acute distress. skin is unremarkable. heent: pupils equally round and reactive to light. extraocular movements intact. anicteric, noninjected. mucous membranes moist. neck is supple. no lymphadenopathy. no carotid bruits. chest is clear to auscultation bilaterally with a harsh holosystolic murmur. abdomen is soft, nontender, nondistended, normal active bowel sounds. no hepatosplenomegaly. extremities are warm and well-perfused with no clubbing, cyanosis or edema and no varicosities. neurologically grossly intact, nonfocal exam. as stated previously, the patient was a direct admission to the operating room. please see the or report for full details. in summary, the patient had a minimally invasive mitral valve repair via an anterior approach with a resection of p2 and a 32 mm - ring. the patient's bypass time was 90 minutes with a crossclamp time of 63 minutes. he tolerated the operation well and was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, the patient was in sinus rhythm at 88 beats per minute with a mean arterial pressure of 69 and a cvp of 2. he had neo-synephrine at 0.3 mics/kilogram/minute. the patient did well in the immediate postoperative period. he was hemodynamically stable. his anesthesia was reversed and he was initially weaned from the ventilator. however, he did experience some co2 retention and, therefore, he was put back on a mandatory rate with the ventilator overnight. on the morning of postoperative one, the patient remained hemodynamically stable with adequate blood gases. he was weaned from the ventilator and successfully extubated. however, he continued to require neo-synephrine infusion to maintain an adequate blood pressure and he stayed in the cardiothoracic unit throughout postop day 1. by postoperative day 2, the patient had been weaned off his neo- synephrine drip. he remained hemodynamically stable. his chest tubes were removed as was his central venous catheter, and his foley catheter, and he was transferred to the floor for continuing postoperative care and cardiac rehabilitation. over the next several days, the patient had an uneventful hospital course. his activity level was increased with the assistance of the nursing staff as well as the physical therapy staff, and on postoperative day 5, it was decided that the patient was stable and ready to be discharged to home. at the time of this dictation, the patient's physical exam is as follows: vital signs: temperature 98.6, heart rate 88 sinus rhythm, blood pressure 130/60, respiratory rate 18, o2 sat 98 percent on room air. weight on day of discharge 95 kg, preoperatively 85 kg. laboratory data: white count 3.9, hematocrit 23.5, platelets 185, sodium 141, potassium 4.4, chloride 103, co2 30, bun 10, creatinine 1.0, glucose 97. physical exam: neuro: alert and oriented x3. moves all extremities. follows commands. nonfocal exam. pulmonary: clear to auscultation bilaterally. cardiovascular: regular rate rhythm, s1-s2 with no murmurs. sternum is stable. incision with steri-strips open to air, clean and dry. abdomen: soft, nontender, nondistended, normal active bowel sounds. extremities: warm with trace edema. patient's condition at time of discharge is good. discharge diagnoses: include status post minimally-invasive mitral valve repair. discharged medications: include potassium chloride 20 meq po q.daily x 2 weeks, colace 100 mg b.i.d., aspirin 81 mg q.daily, percocet 5/325 1-2 tablets q. 4-6 hours p.r.n., ferrous gluconate 300 mg q.daily x1 month, ascorbic acid 500 mg b.i.d. x1 month, lasix 20 mg q.daily x2 weeks, metoprolol 25 mg b.i.d., and multivitamin one q.daily. th is to have follow-up in the wound clinic in 2 weeks. follow-up with dr. in weeks and follow-up with dr. in 4 weeks. , md procedure: open heart valvuloplasty of mitral valve without replacement diagnoses: mitral valve disorders 

Answer: The patient is high likely exposed to
