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: penicillins / olanzapine attending: chief complaint: increasing dyspnea on exertion major surgical or invasive procedure: 1. mitral valve repair with a 28 mm annuloplasty band and stitch between a1 and p1. 2. coronary artery bypass grafting x1 with left internal mammary artery graft to left anterior descending. history of present illness: 75yo man seen in after chf exacerbation requiring intubation. during that stay patient had acute delerium and was deemed porr surgical candidate at that time. he ultimately was discharged to rehab where after period of recovery he returned home where he lives alone. he has been in relatively good health since that time but recently has been experiencing increasing dyspnea on exertion. he had repeat echo and underwent cardiac catheterization today. he is now referred to re evaluate surgical candidacy. past medical history: mitral regurgitation paroxysmal atrial fibrillation hypertension hypercholesterolemia congestive heart failure chronic obstructive pulmonary disease ?cva obesity past surgical history: s/p left knee replacement s/p right knee surgery social history: race: caucasian last dental exam: lives with:

minimal plaque with bilateral less than 40% carotid stenosis. echo: pre-cpb: the left atrium is mildly dilated. no thrombus is seen in the left atrial appendage. a tiny patent foramen ovale is present. a left-to-right shunt across the interatrial septum is seen at rest. there is mild symmetric left ventricular hypertrophy. overall left ventricular systolic function is low normal (lvef 50-55%). right ventricular chamber size and free wall motion are normal. the ascending aorta is mildly dilated. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. no thoracic aortic dissection is seen. the aortic valve leaflets (3) are mildly thickened. trace aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. there is moderate/severe prolapse of the p1 portion of the posterior mitral leaflet. an eccentric, anteriorly directed jet of 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 also a central mr jet. post-cpb: there is a mitral annular ring in place. the anterior mitral leaflet spans the entire mitral annulus, and the posterior mitral leaflet is minimally visible, consistent with mitral valve repair. there is no residual mr. the lv systolic function appears unchanged from preop, estimated ef 50%. there is no evidence of aortic dissection. dr. was notified in person of the results at time of study. radiology report chest port. line placement study date of 11:07 medical condition: 75 year old man with new picc final report one view. comparison with the previous study done earlier the same day. a picc line has been inserted on the left and terminates in the upper superior vena cava. a right jugular sheath has been withdrawn. there is no other significant change. brief hospital course: mr. presented to for admission prior to surgery for cardiac cath and due to being on coumadin at home for atrial fibrillation. he stopped coumadin prior to admission and was started on iv heparin. following cath he was transferred to the floor for medical management. in addition he underwent extensive surgical work-up which included echo, carotid u/s, pft's and dental clearance. on he was brought to the operating room where he underwent a mitral valve repair and coronary artery bypass graft x 1. please see operative report for surgical details. following surgery he was transferred to the cvicu for invasive monitoring in stable condition. within 24 hours he was weaned from sedation, awoke neurologically intact and extubated. on post-op day one ep was consulted for management of bradycardia, sinus pauses and atrial fibrillation (brady-tachy syndrome). he remained in the cvicu for a week for close rhythm monitoring and management. during this time he was diuresed towards his pre-op weight. chest tubes and epicardial pacing wires were removed per protocol. although pacing wires remained intact for longer due to rhythm issues. heparin, eventually coumadin, and amiodarone were started for atrial fibrillation. on post-op day seven he was transferred to the stepdown floor for further care. on post operative day 8 his rhythm was stable in atrial fibrillation at a rate 90-100's with no required pacing for multiple days. his heparin was stopped at this time and pacing wires were pulled. heparin was then resumed 6 hours later and stopped once patient became therapeutic on coumadin. during post-op period he worked with physical therapy for strength and mobility. on post operative day 9 he was ambulating with assistance, his incisions were healing well and he was tolerating a full oral diet. it was felt that he was safe for discharge to in . he will follow-up with dr in 3 weeks. medications on admission: coumadin 7 alt 6 daily asa 81 mg daily lisinopril 2 mg kcl 10 mg daily metoprolol 5 mg lasix 40a/20p amlopidine 10 mg daily
