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: nkda past medical history: endocarditis with lv abcess ; htn; elevated lipids; s/p avr -aortic root replaced c/b seizure disorder, sever ai,mr requiring prolonged intubation. in miuc c/b ards -> prolonged intubation paralytics, worsening arf requiring cavhd and dopa, elevated lft's and new onset pancreatitis. tee showed marked ao root dilitation with paravalvular abcess. review of systems: pt was intubated since admission. initially he had tolerated psv but following a self extubation with probable aspiration he developed early signs of ards and required ac. his vent setting were increased in tidal volume and rate to maintain his abg's. his settings when he left for surgery were ac 600 x22, peep 10, fio2 45%, with abg 127/32/7.42. suctioning thick blood tinged tan secretions cardiac: pt was on dopa initially for blood pressure control but it was stopped when he went into afib . he was started on dobutamine for a trial but it was d/c'ed after 24 hours because it was causing hypotension and afib. he was started on levophed on for dropping blood pressure which it was weaned off by . dobutamine was tried again but he again went into afib so it was stopped . he was started on natrecor on nights . he was on and off a lasix gtt for most of the admission, max. up to 4mg/hr. on he was aggressively bolused with lasix which produced a good duiresis. his b/p was 120-180/30-40's, hr 70-80's sr. neuro: he was very hard to keep sedated. he was on ativan and fentanly since admission in increasing amounts. prior to discharge he was on ativan 4mg/hr and fentanyl 300mcg/hr. he required paralyzation on due to inability to ventilate. he was on cisatricurium at 0.2 mg/kg/hr. gu: he had periods of renal insufficiency with a creat up to 3.6 on . this episode improved when his u/o increased but by the time of transfer his bun was 119/ creat 2.0. the plan was for intra-op dialysis to decrease his bun. gi: he was on and off tube feeds due to tolerance. he was started on tpn . he was having mucous like stool from daily dulcolax supp. the stools were blood streaked from ? internal hemorroids. id: pt was having frequent temps from an unknown source. the possible source was the aortic root and valve placed on . he was on vanco and levo at transfer. his wbc's 8.7 on . procedure: continuous invasive mechanical ventilation for 96 consecutive hours or more extracorporeal circulation auxiliary to open heart surgery parenteral infusion of concentrated nutritional substances (aorto)coronary bypass of two coronary arteries intraoperative cardiac pacemaker hemodialysis percutaneous [endoscopic] gastrostomy [peg] reopening of recent thoracotomy site temporary tracheostomy open and other replacement of aortic valve with tissue graft closed [endoscopic] biopsy of bronchus pericardiotomy percutaneous [endoscopic] gastrojejunostomy open heart valvuloplasty of mitral valve without replacement diagnoses: acute kidney failure with lesion of tubular necrosis atrial fibrillation mitral valve insufficiency and aortic valve insufficiency hemorrhage complicating a procedure acute and subacute bacterial endocarditis infection and inflammatory reaction due to cardiac device, implant, and graft adhesive pericarditis 

Answer: The patient is high likely exposed to
