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: sypnea on exertion, orthopnea major surgical or invasive procedure: redo avr (23mm st. mechanical)/ cabg x1 (svg to pda) history of present illness: 56 yo male with prior tissue avr in presented to er in with 2-3 weeks gradual orthopnea and doe. admitted to icu for chf and hypertensive emergency and was diuresed. originally evaluated by dr. at that time. returned for surgery after pre-op evaluation completed. past medical history: s/p renal transplant , baseline creatinine 3.0 avr , bovine valve s/p endocarditis , , prostate ca s/p xrt melanoma on neck s/p resection hypertension hyperlipidemia gout gi bleed/hemorrhoids ( banded) remote fracture left shoulder s/p parathyroidectomy social history: social history is significant for the absence of any tobacco use. there is no history of alcohol abuse. lives with wife. family history: there is no family history of premature coronary artery disease or sudden death. father had mi when he was older. physical exam: 69" 160# hr 72 rr 20 bp 144/91 normocephalic, well-nourished skin/heent unremarkable neck incison healed ctab rrr with 3/6 systolic murmur abd soft/nd extrems warm, well-perfused; 1+ edema no varocosities noted neuro grossly intact 3+ bil. femorals 2+ bil. dp/pt/radials left carotid bruit noted pertinent results: conclusions pre bypass: this study is limited by poor image quality and a rotated heart with off axis views only. right ventricular chamber size and free wall motion are normal. there are complex (>4mm) atheroma in the aortic arch. there are complex (>4mm) atheroma in the descending thoracic aorta. the prosthetic aortic valve leaflets are thickened. significant aortic stenosis is present (not quantified) insitu aortic valve prosthesis appears heavily calcified. no aortic regurgitation is seen. the mitral valve leaflets are moderately thickened. mild to moderate (+) mitral regurgitation is seen. post bypass: patient is on epinepherine 0.02 mcg/kg/min, and phenylepherine 1 mcg/kg/min, v paced biventricular funciton is slightly improved with mild to moderate residual hypokinesis in the inferior wall. a mechanical prosthethesis is seen in the aortic position with a peak gradient of 20 on average. no ai or perivavlvuar leaks are seen. mitral regurgitation is now mild. aortic contours are intact. remaining exam is unchanged. all finidings discussed with surgeons at the time of the exam. i certify that i was present for this procedure in compliance with hcfa regulations. electronically signed by , md, interpreting physician 14:22 ??????
