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: mitral valve endocarditis major surgical or invasive procedure: - mvr (29mm ce thermafix pericardial valve) history of present illness: is a 26-year-old female who presented approximately 6-1/2 weeks ago with severe mitral regurgitation and shortness of breath and found to have, by echocardiography, evidence of mitral valve endocarditis. the infectious disease service was consulted at that time and it was elected to treat her with a complete course of antibiotics given that she was hemodynamically stable in an effort to allow as completely treatment as possible, and this was accomplished over the next 6 weeks through a picc line. she had multiple negative blood cultures since. a repeat echocardiogram on the day prior to surgery showed persistence of the mitral valve regurgitation of 4+. she is presenting for mitral valve replacement. she elected to have a tissue valve placed in an effort to avoid long-term coumadin therapy so that she has the option of having a pregnancy. she realizes that down the road she will need redo surgery given her young age with a tissue prosthesis. past medical history: sub acute endocarditis right sacroiliatis social history: the patient moved out from her parents home 6 months ago butcame back after she started having the "anxiety attacks". she works as an accountant. she denies any use of tobacco or illicit drugs. she drinks occasionally etoh. family history: father with htn grand mother lung cancer. physical exam: vitals: t:98 p:88 r: 18 bp:92/64 sao2: 100 ra general: awake, alert, nad. heent: moist oral mucose, exteernal ocular movements preserved. no lad, no jvd appreciated. neck supple pulmonary: lungs decrease breath sounds on the right base, decrease fremitus on the right base. no crackles. cardiac: rrr, nl. s1s2, iv/vi murmus holosytolic in the apex. abdomen: soft, nt/nd, normoactive bowel sounds, no masses or organomegaly noted. extremities: no edema, distal pulses preserved. right leg: range of movement preserved proximal and distal. straight leg raising negative. skin: no rashes or lesions noted. back: no costovertebral tenderness, pain to palpation over the right iliac bone. no point-tenderness over midline. neurologic: alert, oriented x 3, non focal. strength preserved le. pertinent results: 06:15am blood wbc-14.6* rbc-3.23* hgb-8.6* hct-25.5* mcv-79* mch-26.7* mchc-33.8 rdw-18.4* plt ct-109* 06:15am blood plt ct-122* 04:25am blood k-4.2 06:15am blood glucose-101 urean-8 creat-0.5 na-136 k-4.0 cl-100 hco3-26 angap-14 echo pre-bypass: the left atrium is dilated. no spontaneous echo contrast or thrombus is seen in the body of the left atrium/left atrial appendage or the body of the right atrium/right atrial appendage. a moderately dilated left ventricle, normal thickness and borderline normal lv systolic function.(lvef 50-55%). right ventricular chamber size and free wall motion are normal. the ascending, transverse and descending thoracic aorta are normal in diameter and free of atherosclerotic plaque. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. the mitral leaflets are thickened. there is a torn chordae supporting the posterior mitral leaflet. there is a freely mobile echodensity of 0.9cm on the left atrial aspect of the posterior mitral leaflet c/w with a vegetation. the p1 and p2 scallops of the pml are destroyed giving rise a severe mitral regurgitant jet with a flow reversal in the right and left sided pulmonary veins. no perforations are seen in the anterior mitral leaflet. there is a trivial tr and pi. post_bypass: preserved right ventricular systolic function. lvef 45-50%. a bioprosthesis is seen in the native mitral position, well seated and opening and closing well with no leaks. the gradients are pg11 and mean 5. aortic valve is intact and aortic contour is well preserved. cxr increased left pleural effusion and left lower lobe atelectasis. in the setting of dropping hematocrit as indicated in the history, clinical correlation is recommended. stable tiny right pleural effusion. brief hospital course: ms. was admitted to the on for surgical management of her mitral valve disease. her picc line was removed and an echocardiogram was repeated. this showed severe 4+ mitral regurgitation with a normal ejection fraction. on , ms. was taken to the operating room where she underwent a mitral valve replacement using a 29mm thermafix pericardial valve. postoperatively she was taken to the cardiac surgical intensive care unit for monitoring. she awoke neurologically intact and was extubated. she was then transferred to the step down unit for further recovery.the infectious disease service continued to follow her postoperatively. her vancomycin dose was increased to 1.25 grams twice daily. her drains and wires were removed per protocol. she was gently diuresed towards her preoperative weight. the physical therapy service was consulted for assistance with her strength and mobility. as her valve culture and pathology returned negative, her antibiotics were discontinued. dilaudid was used with good pain relief. ms. continued to make steady progress and was discharged home on postoperative day four. she will follow-up with dr. , her cardiologist or primary care physician as an outpatient. medications on admission: iv ceftriaxone discharge medications: 1. metoprolol tartrate 25 mg tablet sig: 0.5 tablet po
