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: severe mitral regurgitation status post minimally invasive mitral valve repair. major surgical or invasive procedure: redo mitral valve surgery with mitral valve replacement, 27 mm biocor tissue valve. history of present illness: mr. is a 70-year-old male who 1 week earlier underwent mitral valve repair for a flail posterior leaflet and a myxomatous valve through a right minithoracotomy minimally invasively. his postoperative tee at the time of surgery showed an intact repair with no mitral regurgitation whatsoever. he was discharged from the hospital 3 days later with no murmur and feeling well. however, on the 5th postoperative day he presented to an outside hospital complaining of shortness of breath and found to have a murmur and echocardiogram showed moderate to severe mitral regurgitation. he was admitted urgently to the icu and tee that showed dehiscence of the mitral annuloplasty band posteriorly. he was brought to the operating room for mitral valve surgery through a median sternotomy. past medical history: past medical history: mitral and aortic valve

thrombus in the body of the laa. all four pulmonary veins identified and enter the left atrium. right atrium/interatrial septum: normal ra size. a catheter or pacing wire is seen in the ra. pfo is present. left-to-right shunt across the interatrial septum at rest. left ventricle: wall thickness and cavity dimensions were obtained from 2d images. normal lv wall thickness and cavity size. low normal lvef. right ventricle: normal rv chamber size. mildly dilated rv cavity. mild global rv free wall hypokinesis. aorta: normal ascending aorta diameter. simple atheroma in ascending aorta. normal descending aorta diameter. simple atheroma in descending aorta. aortic valve: three aortic valve leaflets. mildly thickened aortic valve leaflets (?#). no as. trace ar. mitral valve: bioprosthetic mitral valve prosthesis (mvr). mitral valve annuloplasty ring. abnormal mvr motion c/w partial dehiscence. severe (4+) mr. to the eccentric mr jet, its severity may be underestimated (coanda effect). tricuspid valve: normal tricuspid valve leaflets. mild tr. pulmonic valve/pulmonary artery: normal pulmonic valve leaflet. no ps. physiologic pr. pericardium: no pericardial effusion. pre-bypass: the left atrium is mildly dilated. no spontaneous echo contrast or thrombus is seen in the body of the left atrium or left atrial appendage. a patent foramen ovale is present. a left-to-right shunt across the interatrial septum is seen at rest. left ventricular wall thicknesses and cavity size are normal. overall left ventricular systolic function is low normal (lvef 50-55%). right ventricular chamber size is normal. the right ventricular cavity is mildly dilated with mild global free wall hypokinesis. there are simple atheroma in the ascending aorta. there are simple atheroma in the descending thoracic aorta. there are three aortic valve leaflets. the aortic valve leaflets are mildly thickened . there is no aortic valve stenosis. trace aortic regurgitation is seen. a mitral valve annuloplasty ring is present. the annunloplasty ring has dehisced and has dissociated from the posterior mitral annular region. motion of the mitral annulus is abnormal and suggestive of partial dehiscence. severe (4+) mitral regurgitation is seen. due to the eccentric nature of the regurgitant jet, its severity may be significantly underestimated (coanda effect). there is no pericardial effusion. post cpb: 1. there is a bioprosthetic prosthesis in mitral position. well seated and stable with good leqaflet excursion. there is no mr. gradient is 17 mm hg and mean gradient is 11 mm hg. (cardiac output 6.5 liters/min with epinephrine infusion) 2. lv and rv systolic functions are unchanged. 3. intact aorta. brief hospital course: 70 yo male admitted with shortness of breath and increasing lower extremity edema. after tee showed dehiscence of the mitral annuloplasty band posteriorly, the patient was taken on to the operating room for a redo mitral valve surgery with mitral valve replacement, 27 mm biocor tissue valve via median sternotomy. see operative note for full details. he was transported to the intensive care unit and weaned off of all vasoactive medications on post operative night. he was extubated without incidence on post operative night. he was started on beta blockers and they were increased as needed. chest tubes and pacing wires were removed per cardiac surgery protocol. he was transferred to the floor on post operative day # 1. he continued to work with physical therapy for improving strength and endurance. he was diuresing well with lasix twice a day. he was tolerating a full po diet, his incisions were healing well and he was ambulating with assistance on post operative day 4. it was felt that he was safe for discharge to home with vna services at this time. medications on admission: lopressor 25 , lasix 40 po daily, kcl, colace, omeprazole, asa, ibuprofen tid discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 2. aspirin 81 mg tablet, delayed release (e.c.) sig: one (1) tablet, delayed release (e.c.) po daily (daily). disp:*100 tablet, delayed release (e.c.)(s)* refills:*2* 3. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po q4h (every 4 hours) as needed for pain. disp:*30 tablet(s)* refills:*0* 4. omeprazole 20 mg capsule, delayed release(e.c.) sig: one (1) capsule, delayed release(e.c.) po daily (daily). disp:*30 capsule, delayed release(e.c.)(s)* refills:*2* 5. metoprolol tartrate 50 mg tablet sig: one (1) tablet po tid (3 times a day). disp:*90 tablet(s)* refills:*1* 6. lasix 40 mg tablet sig: one (1) tablet po twice a day for 10 days. disp:*20 tablet(s)* refills:*0* 7. potassium chloride 20 meq tab sust.rel. particle/crystal sig: two (2) tab sust.rel. particle/crystal po once a day for 10 days. disp:*20 tab sust.rel. particle/crystal(s)* refills:*0* 8. acetaminophen 325 mg tablet sig: two (2) tablet po q4h (every 4 hours) as needed for pain/fever. tablet(s) 9. magnesium hydroxide 400 mg/5 ml suspension sig: thirty (30) ml po hs (at bedtime) as needed for constipation. discharge disposition: home with service facility: community nurse care,inc discharge diagnosis: severe mitral regurgitation status post minimally invasive mitral valve repair. discharge condition: alert and oriented x3 nonfocal ambulating, gait steady sternal pain managed with percocet prn discharge instructions: please shower daily including washing incisions gently with mild soap, no baths or swimming, and look at your incisions please no lotions, cream, powder, or ointments to incisions each morning you should weigh yourself and then in the evening take your temperature, these should be written down on the chart no driving for approximately one month until follow up with surgeon no lifting more than 10 pounds for 10 weeks please call with any questions or concerns females: please wear bra to reduce pulling on incision, avoid rubbing on lower edge followup instructions: please call to schedule appointments surgeon dr in 4 weeks primary care dr in weeks cardiologist dr 1-2 weeks wound check appointment - 6 () - your nurse will schedule procedure: extracorporeal circulation auxiliary to open heart surgery open and other replacement of mitral valve with tissue graft diagnoses: esophageal reflux mitral valve disorders congestive heart failure, unspecified unspecified essential hypertension disruption of internal operation (surgical) wound hypertrophy (benign) of prostate without urinary obstruction and other lower urinary tract symptom (luts) other and unspecified hyperlipidemia acute diastolic heart failure
