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: sob, peripheral edema, fatigue major surgical or invasive procedure: pacemaker placement history of present illness: 22 y/o male presented to with 2 week history of cough, peripheral edema, sob & fatigue. he was found to have a lbbb, elev. bnp, and depressed lv function. tee revealed aortic valve endocarditis. he was transferred to on for surgical intervention. past medical history: hep c positive ivdu (cocaine & heroin) 3ppd smoker (since age 10) social history: incarcerated at the time of admission to smokes 3ppd ivdu (heroin & cocaine) family history: non-contributory physical exam: bibasilar crackles holosystolic murmur 1+ ankle edema bilat otherwise exam upon admission was unremarkable pertinent results: 08:05am blood wbc-10.7 rbc-3.75* hgb-10.8* hct-30.4* mcv-81* mch-28.8 mchc-35.5* rdw-15.2 plt ct-289 07:14am blood wbc-12.3* rbc-4.12* hgb-11.4* hct-33.6* mcv-82

valve disease. endocarditis. height: (in) 71 weight (lb): 157 bsa (m2): 1.90 m2 bp (mm hg): 102/28 hr (bpm): 90 status: inpatient date/time: at 15:49 test: tee (complete) doppler: full doppler and color doppler contrast: none tape number: 2006w000-0:00 test location: west cath/ep lab technical quality: adequate referring doctor: dr. measurements: left ventricle - ejection fraction: 30% to 35% (nl >=55%) interpretation: findings: left atrium: dilated la. right atrium/interatrial septum: dilated ra. a catheter or pacing wire is seen in the ra and extending into the rv. no asd by 2d or color doppler. left ventricle: dilated lv cavity. moderate global lv hypokinesis. aorta: no atheroma in aortic arch. no atheroma in descending aorta. aortic valve: bicuspid aortic valve. moderately thickened aortic valve leaflets. large vegetation on aortic valve. aortic root abscess. severe (4+) ar. mitral valve: normal mitral valve leaflets. no mass or vegetation on mitral valve. trivial mr. tricuspid valve: normal tricuspid valve leaflets. no mass or vegetation on tricuspid valve. mild tr. pulmonic valve/pulmonary artery: normal pulmonic valve leaflets with physiologic pr. pericardium: small to moderate pericardial effusion. general comments: the patient was monitored by a nurse e throughout the procedure. the posterior pharynx was anesthetized with 2% viscous lidocaine. no tee related complications. 0.2 mg of iv glycopyrrolate was given as an antisialogogue prior to tee probe insertion. conclusions: the left atrium is dilated. the right atrium is dilated. no atrial septal defect is seen by 2d or color doppler. the left ventricular cavity is dilated. there is moderate global left ventricular hypokinesis. the transverse and descending thoracic aorta are normal in diameter and free of atherosclerotic plaque. the aortic valve is bicuspid. the aortic valve leaflets are moderately thickened. there is a large (2 x 0.7 cm) vegetation on the posterior aortic valve leaflet. an aortic annular abscess is seen in the intervalvular fibrosa (best seen at the base of the anterior mitral valve leaflet). severe (4+) aortic regurgitation is seen. the mitral valve leaflets are structurally normal. no mass or vegetation is seen on the mitral valve. trivial mitral regurgitation is seen. there is a small to moderate sized circumferential pericardial effusion. impression: bicuspid aortic valve with a large (2 x 0.7 cm) vegetation on the posterior leaflet with severe aortic regurgitation. small (0.4 x 0.8 cm) abscess that appears to be in the intervalvular fibrous tissue (between the aortic valve and mitral valve), best visualized at the base of the anterior mitral valve leaflet. the left ventricle is severely dilated with moderate global hypokinesis. small to moderate circumferential pericardial effusion. electronically signed by , md on 19:26. physician: , . chest (pa & lat) 9:11 am chest (pa & lat) reason: lead placement medical condition: 22 year old man with av endocarditis s/p single cahmber pacemaker reason for this examination: lead placement chest x-ray with pa and lateral views indication: patient is status post single chamber pacemaker placement. comparisons: . cardiomegaly is unchanged. again seen is a single chamber pacemaker with lead wire in appropriate position without change. there is no evidence of pneumothorax. compared to , there are increased pulmonary markings in a more patchy distribution, particularly in the right lower lobe that are concerning for an underlying infectious process. the upper lung zones are otherwise clear. there are no pleural effusions. the osseous structures and soft tissues are unremarkable. impression: 1. new patchy-like opacities within right lower lobe could reflect new underlying infectious process. clinical correlation advised. 2. no evidence of pneumothorax. 3. persistent cardiomegaly. brief hospital course: mr. was admitted to the csru from outside hospital. remained hemodynamically stable. id consult obtained. since there was no documented bacteria, broad spectrum antibiotics were initiated. he was started on gentamicin (for an empiric 7 day course), vancomycin, and ceftriaxone (for a week course of each). a right pleural effusion was tapped (600 cc straw colored fluid obtained). the electrophysiology service was consulted due to the history of heart block as well as aortic root abscess. a temporary pacemaker was placed initially. this was converted to a permanent vvi pacemaker on . it will likely be replaced with an epicardial lead system when he is ultimately taked to the or for an aortic valve/root replacement upon completion of his antibiotic course. he was transferred to the telemetry floor where he has remained hemodynamically stable. he has had a neurology consult (due to a small frontal lobe lesion noted on mri). this was felt to be a small embolic infarct, and only a small risk of hemmorhage is likely with anticoagulation. they did, however, recommend a full antibiotic course prior to surgery. opthalmology consult revealed a small hemmorhagic lesion in the left eye which required no intervention. hepatology consult revealed no evidence of cirrhosis, and no contraindication to surgery. he is to be transferred to to complete his antibiotic course (both ceftriaxone and vancomycin should be administered through ). he will then be re-evaluated for aortic valve/root replacement. medications on admission: on transfer from : nitroglycerine gtt vancomycin gentamicin nafcillin lasix 40mg iv
