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 56 year old man who reports a history of mitral valve disease and atrial fibrillation first diagnosed approximately five years ago. his most recent echocardiogram was from . this was remarkable for mildly enlarged left ventricle with normal systolic function. there was mitral valve prolapse with moderate to severe mitral regurgitation along with severe left atrial enlargement. the patient states he feels in his usual state of health. he denies any chest pain, shortness of breath or palpitations. he does have occasional lower extremity edema. he denies claudication, orthopnea, paroxysmal nocturnal dyspnea and light-headedness. height six feet three inches, weight 275 pounds. past medical history: 1. atrial fibrillation. 2. mitral regurgitation. 3. hypertension. past surgical history: 1. bladder cancer treated surgically in . 2. varicocelectomy. 3. hydrocelectomy. 4. excision of pilonidal cyst. 5. removal of extra digit as a child. allergies: no known drug allergies. medications on admission: 1. coumadin 5 mg q.d. 2. verapamil 240 mg q.d. 3. coenzyme one q.d. laboratory data: white count 7.5, hematocrit 46.1, platelets 286,000. sodium 140, potassium 4.2, chloride 104, co2 28, blood urea nitrogen 18, creatinine 0.9. inr on admission was 1.53. social history: the patient is married and lives in . he works for airline loading planes. the patient was admitted to the cardiology service and brought to the cardiac catheterization laboratory. please see catheterization report for full details. in summary, the catheterization showed 3+ mitral regurgitation with an atrial septal defect, ejection fraction of 50%. and no significant coronary artery disease. following catheterization, the patient was discharged home. hospital course: he was readmitted on , directly to the operating room at which time he underwent repair of his mitral valve and atrial septal defect repair and a procedure. please see the operating room report for full details. in summary, the patient as stated earlier had a resection of his mitral valve, the repair with a 28 ring and atrial septal defect repair and a procedure. he was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, he had an arterial line, swan-ganz catheter, atrial and ventricular pacing wires and mediastinal chest tubes. at that time, his mean arterial pressure was 69 with a cvp of 11. he had epinephrine, milrinone, nitroglycerin and propofol infusing at the time of transfer. after arrival to the intensive care unit, the patient was weaned from the epinephrine. his milrinone was slowly weaned during the course of operative day number one. a chest x-ray done upon arrival to the intensive care unit showed left sided fluid collection. at that time, a #28 french chest tube was placed. unfortunately, we were unable to evacuate the fluid collection at that time. due to difficulty oxygenating the patient, the patient was kept sedated following his surgery. on postoperative day one, the patient's sedation was discontinued. he was weaned to pressure support ventilation. at that time, he remained hemodynamically stable, however, he did experience episodes of rapid atrial fibrillation. for this, he was bolused with amiodarone, however, he remained in rapid atrial fibrillation despite the amiodarone infusion. on the morning of postoperative day three, the patient was extubated with the assistance of anesthesia due to the fact that he was a difficult intubation. on postoperative day three, it was noted that the patient had a temperature to 102.7. at that time, he had a chest x-ray, blood, urine and sputum cultures. on postoperative day four, the patient remained hemodynamically stable in atrial fibrillation despite being maintained on an amiodarone drip. all other cardioactive medications, intravenous medications had been weaned to off by that point. he remained in the intensive care unit on postoperative day four to further monitor his pulmonary status. on postoperative day five, the patient remained stable from both pulmonary and cardiac state. he was bolused again with another 150 mg amiodarone and heparinized at that point for persistent atrial fibrillation. following his additional bolus with amiodarone, the patient was transferred to the floor for continuing postoperative care and cardiac rehabilitation. over the next several days, the patient's activity level was increased with the assistance of the nursing staff and physical therapy. he slowly progressed from an activity standpoint. on postoperative day eight, it was decided that the patient was stable and ready for discharge to rehabilitation as soon as his inr was within therapeutic range. at that time, the patient's physical examination is as follows: vital signs revealed temperature 98, heart rate 60 and atrial fibrillation, blood pressure 101/57, respiratory rate 22, oxygen saturation 93% on two liters. weight preoperatively is 122.7 kilograms and at discharge is 122.2 kilograms. laboratory data revealed a white count 9.6, hematocrit 32.2, platelets 414,000. prothrombin time 14.3, partial thromboplastin time 26.7, inr 1.4. sodium 140, potassium 4.4, chloride 103, co2, blood urea nitrogen 21, creatinine 0.7, glucose 88. on physical examination, the patient is alert and oriented time three, moves all extremities, follows commands. breath sounds are somewhat decreased at the bases bilaterally; otherwise clear to auscultation the heart sounds revealed irregular rate and rhythm, s1 and s2, no murmurs. sternum is stable. incisions with staples, open to air, clean and dry. the abdomen is soft, nontender, nondistended, normoactive bowel sounds. extremities are warm and well perfused with 1+ pitting edema. medications on discharge: 1. amiodarone 400 mg t.i.d. through , and then 400 mg q.d. 2. potassium chloride 20 meq q.d. 3. lasix 20 mg p.o. q.d. times one week. 4. metoprolol 100 mg b.i.d. 5. levofloxacin 500 mg q.d. times one week. 6. colace 100 mg b.i.d. 7. ranitidine 150 mg b.i.d. 8. percocet 5/325 one to two tablets q4hours p.r.n. 9. coumadin 5 mg q.d. and titrate to keep inr 2.0 to 3.0. condition on discharge: the patient's condition is stable. discharge diagnoses: 1. mitral regurgitation, status post mitral valve repair with a 28 ring. 2. patent ductus arteriosus repair. 3. mays. 4. atrial fibrillation. 5. hypertension. 6. bladder cancer. 7. excision of pilonidal cyst. 8. varicocelectomy. 9. hydrocelectomy. 10. removal of an extra digit as a child. th is to be discharged to rehabilitation. anticipated date of discharge is . he is to have follow-up in wound clinic in two weeks and follow-up with his primary care physician in three to four weeks and follow-up with dr. in four weeks. , m.d. dictated by: medquist36 procedure: extracorporeal circulation auxiliary to open heart surgery diagnostic
