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: dyspnea on exertion major surgical or invasive procedure: redo, redo-sternotomy, pulmonic valve replacement with 25mm mosaic aortic porcine valve/right ventricular outflow tract reconstruction with pericardial patch cardiac cath history of present illness: 54 y/o male c/p dyspnea on exertion with h/o congenital aortic valve disease s/p aortic valve repair ('s) and s/ procedure (). he has been undergoing routine echocardiograms and most recent has shown worsening pulmonic stenosis/suprapulmonic stenosis stenosis of homograft (incr. peak/mean) with moderate tr. past medical history: hypertension, congenital aortic valve disease s/p av repair ('s) and procedure () social

a normal lmca. the lad had a 50-60% stenosis in its mid portion. the lcx was normal. the rca had luminal irregularities but no angiographically significant cad. 2. resting hemodynamics revealed markedly elevated right ventricular pressures; rv systolic pressure was 85-90 mmhg and rv filling presure was 18 mmhg. there was a 60-70 mmhg gradient between rv and pa. systemic arterial pressures were normal; lv filling pressure was mildly elevated. 3. there was a 60-mmhg gradient at/across the pulmonic valve. there was trivial mitral regurgitation. aortography did not demonstrate any significant ai. echo: pre-bypass: 1. the left atrium is normal in size. the right atrium is moderately dilated. no atrial septal defect is seen by 2d or color doppler. 2. left ventricular wall thicknesses and cavity size are normal. overall left ventricular systolic function is normal (lvef>55%). 3. the right ventricular free wall is hypertrophied. the right ventricular cavity is moderately dilated. there is mild global right ventricular free wall hypokinesis. 4. the aortic root is moderately dilated athe sinus level. there are focal calcifications in the aortic arch. there are simple atheroma in the descending thoracic aorta. 5. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion. there is no aortic valve stenosis. mild to moderate (+) aortic regurgitation is seen. 6. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. 7. there is severe pulmonic valve stenosis. 8. there is no pericardial effusion. post-bypass: for the post-bypass study, the patient was receiving vasoactive infusions including phenylephrine 1. a bioprosthesis is well seated in the pulmonic position. no significant pr is seen. visualization of the valve was suboptimal. 2. biventricular function is preserved. 3. other findings are unchanged. cxr: there is no pneumothorax or increased pleural effusion after removal of two chest tubes. there is improvement in the aeration of the bases bilaterally with still residual linear atelectasis present in the right lung. the heart size and mediastinal contours are unchanged. the replaced pulmonary valve is demonstrated. the lucency between the sternal areas is again noted. the patient's radiograph doesn't demonstrate evidence of congestive heart failure. 09:00am blood wbc-5.2

undergo cardiac cath and other work-up prior to surgery. on he was then brought to the operating room where he underwent redo, redo-sternotomy, pulmonic valve replacement, and right ventricular outflow tract reconstruction. please see operative report for surgical details. following surgery he was transferred to the csru for invasive monitoring in stable condition. within 24 hours he was weaned from sedation, awoke neurologically intact and extubated. on post-op day one he was started on beta blockers and diuretics and diuresed towards his pre-op weight. later on this day he was transferred to the telemetry floor for further care. on post-op day two his mediastinal chest tubes were removed and on post-op day three he pleural chest tubes were removed. also on post-op day three his epicardial pacing wires were removed. his medication were titrated for maximum hemodynamics and he worked with physical therapy for strength and mobility. he did require aggressive pulmonary toilet and needed oxygen via nasal cannula for several days to maintain his oxygen saturation above 93%. this was slowly weaned and he was discharged home on post-operative day four with the appropriate meds and follow-up appointments. medications on admission: aspirin 325mg qd, diltiazem 120mg qd, diovan 80mg qd discharge medications: 1. aspirin 81 mg tablet, delayed release (e.c.) sig:
