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: pollen extracts attending: chief complaint: doe major surgical or invasive procedure: mvr (tissue), maze, laa ligation history of present illness: known mr, afib,

inpatient date/time: at 09:10 test: tee (complete) doppler: full doppler and color doppler contrast: none tape number: 2007aw2-: test location: anesthesia west or cardiac technical quality: adequate referring doctor: dr. measurements: left atrium - four chamber length: *7.2 cm (nl <= 5.2 cm) left ventricle - ejection fraction: 50% to 55% (nl >=55%) aorta - valve level: *3.9 cm (nl <= 3.6 cm) aorta - ascending: *3.5 cm (nl <= 3.4 cm) aorta - arch: *3.4 cm (nl <= 3.0 cm) interpretation: findings: left atrium: marked la enlargement. mild spontaneous echo contrast in the laa. no thrombus in the laa. right atrium/interatrial septum: normal ra size. a catheter or pacing wire is seen in the ra and extending into the rv. no thrombus in the raa. no asd by 2d or color doppler. left ventricle: normal lv wall thicknesses and cavity size. normal lv wall thickness. normal lv cavity size. low normal lvef. lv wall motion: basal anterior - normal; mid anterior - normal; basal anteroseptal -

basal anterolateral - normal; mid anterolateral - normal; anterior apex - normal; septal apex - normal; inferior apex - normal; lateral apex - normal; apex - normal; right ventricle: borderline normal rv systolic function. aorta: mildly dilated aortic sinus. normal ascending aorta diameter. normal descending aorta diameter. simple atheroma in descending aorta. aortic valve: three aortic valve leaflets. mildly thickened aortic valve leaflets. no as. trace ar. mitral valve: severely thickened/deformed mitral valve leaflets. myxomatous mitral valve leaflets. partial mitral leaflet flail. no mass or vegetation on mitral valve. mild mitral annular calcification. moderate thickening of mitral valve chordae. no ms. eccentric mr jet. severe (4+) mr. tricuspid valve: normal tricuspid valve leaflets with trivial tr. general comments: a tee was performed in the location listed above. i certify i was present in compliance with hcfa regulations. no tee related complications. the patient received antibiotic prophylaxis. the tee probe was passed with assistance from the anesthesioology staff using a laryngoscope. the patient was under general anesthesia throughout the procedure. conclusions: pre-cpb: 1. the left atrium is markedly dilated. mild spontaneous echo contrast is present in the left atrial appendage. no thrombus is seen in the left atrial appendage. 2. no thrombus is seen in the right atrial appendage no atrial septal defect is seen by 2d or color doppler. 3. left ventricular wall thicknesses and cavity size are normal. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. overall left ventricular systolic function is low normal (lvef 50-55%). 4. right ventricular systolic function is borderline normal. 5. the aortic root is mildly dilated at the sinus level. there are simple atheroma in the descending thoracic aorta. 6. there are three aortic valve leaflets. the aortic valve leaflets are mildly thickened. there is no aortic valve stenosis. trace aortic regurgitation is seen. 7. the mitral valve leaflets are severely thickened/deformed. the mitral valve leaflets are myxomatous. there is partial mitral leaflet flail. there is severe prolapse of the anterior leaflet and prolapse of the posterior leaflet.no mass or vegetation is seen on the mitral valve. there is moderate thickening of the mitral valve chordae. an eccentric jet of severe (4+) mitral regurgitation is seen. the mitral regurgitant jet is die\rected posteriorly. post-cpb: on infusions of epinephrine, milrinone and phenylephrine. well-seated bioprosthetic valve in the mitral position. trivial mr with small perivalvular jet consistent with suture hole, not seen after protamine administration. lv systolic function is preserved on inotropic support. lvef is 55%. rv systolic function was depressed prior to milrinone administration. trace ai. aortic contour is normal post decannulation. electronically signed by , md on 10:40. physician: brief hospital course: mr. was transferred from mwmc s/p catheterization on , for mitral valve replacement. he was taken to the or on for mvr (porcine), maze, and laa ligation. please see operative report for complete details of procedure. post-operatively, he was taken to the csru in stable condition. he was weaned off mechanical ventilation and extubated on the day of surgery. he was started on amiodarone and lopressor (for the maze procedure), but was soon noted to have av dissociation with a rapid junctional escape rhythm. the eps service was consulted, amiodarone and lopressor were stopped, and he returned to nsr. he has since been back on and again off lopressor due to continued episodes of this same av dissociation. he is being anticoagulated for the rhythm issues (pre-op afib, post-op heart block, s/p maze). he has remained hemodynamically stable throughout, and is ready to be discharged home with of hearts monitior. his coumadin will again be followed by dr. office.
