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: fentanyl attending: chief complaint: persistant afib, rca disease on cath major surgical or invasive procedure: cabg x2, maze, laa ligation history of present illness: the patient is 56-year-old gentleman who was initially sent to me for minimally invasive maze procedure for paroxysmal atrial fibrillation. the patient had longer and longer episodes of atrial fibrillation and now constitutes persistent atrial fibrillation. one time he was admitted for his minimally invasive maze procedure and a left atrial clot was noted in his left atrial appendage and he underwent anticoagulation for that with subsequent resolution of his left atrial thrombus. the last time he was admitted to hospital for the minimally invasive maze procedure, a diagnostic cardiac cath was performed by dr. due to some atherosclerosis which was noted on the preoperative ct angiogram to evaluate his left atrium. the diagnostic cardiac cath revealed anomalous right coronary artery with a significant lesion within the mid to proximal segment as well as a subtotally occluded first obtuse marginal coronary artery. the decision was therefore made to proceed with concomitant maze on top of a coronary artery bypass grafting procedure. the patient therefore agreed to proceed past medical history: paroxysmal atrial fibrillation tachybrady syndrome s/p ppm stroke upper gi bleed hepatitis c in the setting of iv drug use diabetes hpertension oesity social history: he is a prior smoker. he is currently self-employed as an exterminator. he used to use iv drugs but does not use them anymore. family history: there is a family history of diabetes and early stroke in his mother. physical exam: general: well appearing male in nad. generalized edema noted. vs: 98.5, 126/78, 102, 20, 98% on ra heent: unremarkable chest: cta bilat. sternal incision well approx, no redness, no drainage. sternum stable. cor: rrr s1, s2 abd: soft, round, nt, nd, +bowel sounds, +flatus. extrem: bilat extrem edema. neuro: intact. pertinent results: , portable tte (complete) done at 11:00:00 am preliminary referring physician information , c. , status: inpatient dob: age (years): 56 m hgt (in): 74 bp (mm hg): 131/76 wgt (lb): 280 hr (bpm): 80 bsa (m2): 2.51 m2 indication: pericardial effusion. icd-9 codes: 423.9, 424.1, 424.0, 424.2 test information date/time: at 11:00 interpret md: , md test type: portable tte (complete) son: , rdcs doppler: full doppler and color doppler test location: / 6 contrast: none tech quality: adequate tape #: 2009w006-0:20 machine: vivid echocardiographic measurements results measurements normal range left atrium - long axis dimension: *5.3 cm <= 4.0 cm left atrium - four chamber length: *5.8 cm <= 5.2 cm right atrium - four chamber length: *5.5 cm <= 5.0 cm left ventricle - septal wall thickness: *1.2 cm 0.6 - 1.1 cm left ventricle - inferolateral thickness: 1.0 cm 0.6 - 1.1 cm left ventricle - diastolic dimension: 4.9 cm <= 5.6 cm left ventricle - systolic dimension: 3.2 cm left ventricle - fractional shortening: 0.35 >= 0.29 left ventricle - ejection fraction: >= 60% >= 55% aorta - sinus level: *4.0 cm <= 3.6 cm aortic valve - peak velocity: 1.6 m/sec <= 2.0 m/sec mitral valve - e wave: 1.2 m/sec tr gradient (+ ra = pasp): *45 mm hg <= 25 mm hg pericardium - effusion size: 1.5 cm findings right atrium/interatrial septum: a catheter or pacing wire is seen in the ra and extending into the rv. left ventricle: normal lv cavity size. overall normal lvef (>55%). no resting lvot gradient. right ventricle: dilated rv cavity. aorta: moderately dilated aortic sinus. aortic valve: mildly thickened aortic valve leaflets. mild (1+) ar. mitral valve: mildly thickened mitral valve leaflets. trivial mr. tricuspid valve: normal tricuspid valve leaflets. mild tr. moderate pa systolic hypertension. pulmonic valve/pulmonary artery: pulmonic valve not well seen. no ps. pericardium: small to moderate pericardial effusion. sgnificant, accentuated respiratory variation in mitral/tricuspid valve inflows, c/w impaired ventricular filling. conclusions the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef>55%). the right ventricular cavity is dilated the aortic root is moderately dilated at the sinus level. the aortic valve leaflets are mildly thickened. mild (1+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. there is moderate pulmonary artery systolic hypertension. there is a small to moderate sized pericardial effusion. there is significant, accentuated respiratory variation in mitral/tricuspid valve inflows, consistent with impaired ventricular filling. the effusion is partially echodense consistent with some degree of organization. interpretation assigned to , md, interpreting physician pathology examination name birthdate age sex pathology #
