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: asymptomatic major surgical or invasive procedure: mvr (33mm st. mechanical valve), asd closure history of present illness: 51 y/o gentleman who had a heart murmur detected on a routine physical exam in . mitral valve prolapse was found and he was watched by serial echocardiogram. more recently, mr. developed bradycardia of 26 and sought attention from his pcp. pacemaker was placed. his most recent echocardigram revealed severe mitral valve regurgitation and he now presents for surgical management. past medical history: mvp/mr s/p #33 mechanical/asd closure sinus bradycardia s/p pm vea (pvcs, bigeminy) broken collar bone as teenager social history: was working as a correction officer. he is single and lives with his mother. has never smoked or used alcohol family history: maternal gm with colon ca. no cad / sudden death physical exam: pulse 60 bp 140/90 74" 240lbs gen: wdwn in nad heart: rrr, iii/vi sem lungs: clear abd: benign neuro: nonfocal pertinent results: 07:10am blood hct-28.0* 07:10am blood pt-29.7* inr(pt)-3.1* 07:10am blood urean-14 creat-0.9 k-4.6 cxr persistent tiny left pneumothorax. ospital course: mr. was admitted to the on for elective surgical management of his mitral valve disease. he was taken to the operating room where he underwent a mitral valve replacement with a 32mm st. mechanical valve and an atrial septal defect closure. postoperatively, his pacemaker was interrogated and reprogrammed by the electrophysiology service. he was then taken to the cardiac surgical intensive care unit for monitoring. on postoperative day one, mr. neurologically intact and was extubated. beta blockade and aspirin were resumed. a chest tube was placed for drainage of a left pleural effusion. coumadin was started for anticoagulation for his mechanical valve. the physical therapy service was consulted for assistance with his postoperative strength and mobility. on postoperative day three, he was transferred to the cardiac surgical nursing floor for further recovery. mr. was gently diuresed toward his preoperative weight. amiodarone was started for atrial tachycardia which was likely atrial fibrillation. as his inr was slow to reach a therapeutic range, heparin was started as a bridge. mr. continued to make steady progress and was discharged home on postoperative day seven. on discharge, his inr was 3.1, his wounds were clean and dry and his hemodynamics were stable. mr. will follow-up with dr. , his cardiologist and his primary care physician as an outpatient. medications on admission: atenolol cozaar discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*0* 2. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*30 tablet, delayed release (e.c.)(s)* refills:*0* 3. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*50 tablet(s)* refills:*0* 4. ferrous sulfate 325 (65) mg tablet sig: one (1) tablet po daily (daily). disp:*30 tablet(s)* refills:*0* 5. ascorbic acid 500 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*0* 6. potassium chloride 10 meq tablet sustained release sig: two (2) tablet sustained release po once a day for 2 weeks. disp:*28 tablet sustained release(s)* refills:*0* 7. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 8. furosemide 40 mg tablet sig: one (1) tablet po once a day for 2 weeks. disp:*14 tablet(s)* refills:*0* 9. amiodarone 200 mg tablet sig: as directed tablet po bid (2 times a day): 400mg x1 wk then 400mg qd x1 wk then 200mg qd . disp:*60 tablet(s)* refills:*2* 10. warfarin 2 mg tablet sig: as directed tablet po once a day: 4 mg and thenas directed by dr office. disp:*60 tablet(s)* refills:*0* discharge disposition: home with service facility: nashobavna discharge diagnosis: s/p mvr(#33 mechanical)/asd closure pmh:mr,asd,ppm for bradycardia,vertigo,vea, collarbone fracture discharge condition: good. discharge instructions: call with fever, redness or drainage from incision or weight gain more than 2 pounds in one day or five in one week. shower, no baths, no lotions, creams or powders to incisions. no heavy lifting or driving. p instructions: dr. 2 weeks and for coumadin dosing. clinic in 2 weeks dr. 4 weeks procedure: extracorporeal circulation auxiliary to open heart surgery open and other replacement of mitral valve other and unspecified repair of atrial septal defect transfusion of packed cells transfusion of other serum continuous intra-arterial blood gas monitoring diagnoses: mitral valve disorders other specified cardiac dysrhythmias ostium secundum type atrial septal defect cardiac pacemaker in situ
