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 76 year old female patient with known history of mitral valve prolapse with increasing left atrial and left ventricular size and previous history of chest pain and syncope with beta blockers and ace inhibitors. past medical history: 1. the patient is status post colectomy in secondary to colon cancer. 2. she is status post hip replacement in . 3. she is status post left elbow replacement in . 4. status post cholecystectomy. medications: preoperative medications include: 1. enteric coated aspirin one p.o. q. day. allergies: the patient states allergies to penicillin, ace inhibitors, morphine, which gives her gi upset. physical examination: on admission on general examination, the patient appears to be in good general health. skin unremarkable. heent unremarkable. neck with full range of motion. chest: breath sounds are clear bilaterally. cardiac examination is grade v/vi murmur with an irregular rhythm. abdomen is unremarkable. extremities are warm and well perfused. bilateral varicosities of her lower extremities. neurologically, was grossly intact. hospital course: the patient was admitted to the hospital on and taken to the operating room with dr. , where she underwent a mitral valve replacement with a #31 porcine mosaic valve. postoperatively, she was transported from the operating room to the cardiac surgery recovery room in stable condition on a neo-synephrine drip for some transient hypotension. postoperative day one, the patient remained in low-dose neo-synephrine due to continued hypotension however, was hemodynamically stable in a regular heart rhythm. she was weaned from mechanical ventilator and extubated successfully. on postoperative day two, she was weaned off her neo-synephrine drip and transferred from the intensive care unit. her chest tubes were removed on postoperative day two. the patient had transient decrease in her platelet count. her heparin and zantac were discontinued at that time prophylactically. physical therapy evaluation was obtained on postoperative day two and cardiac rehabilitation was initiated. the patient progressed well from a cardiac rehabilitation standpoint. on postoperative day three, in the early morning, the patient was noted to be in atrial fibrillation with variable ventricular rate. she was treated with intravenous beta blocker and p.o. amiodarone was initiated for postoperative atrial fibrillation. the patient subsequently converted to normal sinus rhythm. the patient continued to progress from an ambulatory status. she is able to ambulate to a level of 5 cardiac rehabilitation status. her oxygen was weaned off and she remains on room air with acceptable oxygen saturation of 92 to 95% on room air. the patient continued to progress from chest physical therapy and ambulation and pulmonary toilet standpoints. today, postoperative day five, , she remains hemodynamically stable. vital signs are as follows: temperature 97.2 f.; pulse 58 and normal sinus rhythm; blood pressure 100/55; respiratory rate 18; oxygen saturation as previously stated. most recent laboratory values are from , which revealed a white blood cell count of 5,300, hematocrit of 27.7, platelet count of 82,000. sodium 138, potassium 4.6, chloride 103, co2 29, bun 17, creatinine 0.7, glucose of 92. most recent chest x-ray is also from , which reveal small bilateral effusions with concurrent atelectasis, bilateral bases. physical examination today is: coronary examination is regular rate and rhythm. pulmonary examination: her lungs are clear to auscultation bilaterally. her abdomen is soft, nontender, nondistended with positive bowel sounds. her incision is clean, dry and intact. her extremities are warm without edema. discharge medications: 1. lasix 20 mg p.o. q. day times one week. 2. colace 100 mg p.o. twice a day. 3. enteric coated aspirin 325 mg p.o. q. day. 4. prevacid 30 mg q. day. 5. potassium chloride 20 meq p.o. q. day. 6. lopressor 25 mg p.o. twice a day. 7. amiodarone 400 mg p.o. three times a day times four more days, and then to be decreased to 400 mg p.o. twice a day times one week, then to 400 mg p.o. q. day. this should be continued for four to six weeks postoperatively at the discretion of her primary care physician /or primary cardiologist. this is for treatment of postoperative atrial fibrillation. 8. ibuprofen 400 mg p.o. q. six hours p.r.n. pain. 9. percocet 5/325 one p.o. q. four hours p.r.n. pain. condition at discharge: stable. discharge diagnoses: 1. mitral valve prolapse status post mitral valve replacement. 2. postoperative atrial fibrillation. discharge instructions: 1. the patient is to follow-up with her primary care physician, . , in three to four weeks or p.r.n. upon discharge from the hospital. 2. the patient is to follow-up with dr. , in approximately one month post-surgery. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery open and other replacement of mitral valve with tissue graft diagnoses: mitral valve disorders cardiac complications, not elsewhere classified atrial fibrillation personal history of malignant neoplasm of large intestine hip joint replacement 

Answer: The patient is high likely exposed to
