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: dyspnea on exertion major surgical or invasive procedure: two vessel coronary artery bypass grafting(left internal mammary to left anterior descending, vein graft to diagonal), aortic valve replacement(23mm mosaic porcine), mitral valve replacement(29mm mosaic porcine), and maze procedure re-exploration for bleeding history of present illness: mr. is a 63 year old male with new onset dyspnea on exertion and fatigue. also admits to decreased exercise tolerance and paroxsymal nocturnal dyspnea. an echocardiogram showed mild to moderate aortic insufficiency with moderate to severe mitral regurgitation. his lvef was estimated at 60-65%. he subsequently underwent cardiac catheterization which showed obstructive coronary artery disease(no official report). based on the above results, he was referred for cardiac surgical intervention. past medical history: rheumatic heart disease with history of rheumatic fever, atrial fibrillation, history of pvcs and pacs, history of first degree av block and mobitz i second degree av block, hypertension, prostatism, menieres disease, ?sleep apnea, strabismus repair as a child social history: no history of tobacco. admits to drinking a few beers per week. he is a retired financial manager. he is married and lives with his wife. family history: denies premature coronary artery disease. physical exam: vitals: bp 94-100/60, hr 54, rr 18, sat 98 on room air general: healthy appearing male in no acute distress heent: oropharynx benign, neck: supple, no jvd, transmitted murmur bilaterally heart: regular rate, normal s1s2, holosystolic murmur lungs: clear bilaterally abdomen: soft, nontender, normoactive bowel sounds ext: warm, no edema, no varicosities pulses: 2+ distally neuro: alert and oriented, nonfocal pertinent results: 04:58pm blood wbc-7.3 rbc-4.36* hgb-14.1 hct-39.7* mcv-91 mch-32.2* mchc-35.4* rdw-13.8 plt ct-179 04:58pm blood pt-15.0* ptt-27.2 inr(pt)-1.3* 04:58pm blood glucose-83 urean-24* creat-1.1 na-139 k-4.4 cl-102 hco3-26 angap-15 04:58pm blood alt-42* ast-32 ld(ldh)-267* alkphos-74 amylase-86 totbili-0.5 brief hospital course: mr. was admitted the day prior to surgery for heparinization and preoperative workup. on , he underwent coronary artery bypass grafting, aortic and mitral valve replacements, and a maze procedure by dr. . for further surgical details, please see seperate dictated operative note. after the operation, he was brought to the csru for invasive monitoring. he was noted to have persistent postoperative bleeding which required re-exploration that same day. he returned to the csru in stable condition. on postoperative day one, he awoke neurologically intact and was extubated without incident. he went on to develop hypotension in the setting of atrial fibrillation/flutter with slow ventricular rhythm. he was started on neosynephrine and required vvi pacing to maintain hemodynamics. the cardiology service was consulted and initially recommended to initially hold all nodal agents. there was no indication for temporary pacing wire at that time. over several days, heart rate and hemodynamics improved. neosynephrine was weaned without difficulty and vvi pacing was no longer required. pacing wires were removed on pod3 and patient then transferred to the sdu for further care and recovery. he remained mostly in a atrial fibrillation/flutter with a slow ventricular rate in the 50's. prothrombin times were followed daily and warfarin was dosed for a goal inr between 2.0 - 3.0. a course of antibiotics were given for possible thrombophlebitis. he continued to make clinical improvements with diuresis and was eventually cleared for discharge on pod7. medications on admission: toprol xl 12.5 qd, aspirin 81 qd, lipitor 10 qd, lisinopril 2.5 qd, folate, glucosamine, lasix 20 qd, vitamin c, mvi, fish oil, saw , warfarin -
