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: worsening dyspnea major surgical or invasive procedure: re-do sternotomy for aortic valve replacement (#23 tissue) history of present illness: mr. has known cad, s/p cabg at cmc with cardiac cath in which showed patent graft to rca w/90% stenosis at insertion, to svg to om, patent lima-lad. he has had recent increase in his doe/orthopnea and echo showed severe as, 0.75cm2, peak aortic gradient 69, 2+mr, ef42%. he was admitted last week with increased sob, had mildly elevated

echo contrast is seen in the body of the left atrium. no atrial septal defect is seen by 2d or color doppler. right ventricular chamber size is moderately dilated and there is mild global hypokinesis. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. the aortic valve leaflets are severely thickened/deformed. there is severe aortic valve stenosis (valve area 0.8-1.0cm2). trace aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. there is no mitral valve prolapse. moderate (2+) mitral regurgitation is seen. there is no pericardial effusion. dr. was notified in person of the results on . post-bypass: for the post-bypass study, the patient was receiving vasoactive infusions including epinephrine infusions 0.02 mcg/kg/min, phenylephrine 1.0 mcg/kg/min intact thoracic aorta. moderate mitral regurgitation. mild tricusid regurgitation. there is a bioprosthesis in the native aortic position, stable and functioning well with no residual regurgitation. the mean gradient is 15mm post replacement. mild global rv hypokinesis. lv systolic function is mildly improved with lvef 45%. mild mitral regurgitation. mild . brief hospital course: the patient was admitted for further preop workup. carotid scan revealed <40% stenosis bilaterally. dental clearance was obtained. heparin was initiated for atrial fibrillation. echo revealed critical aortic stenosis with aortic valve area <0.8cm2, 2+ mitral regurgitation and ejection fraction 50-55%. sleep medicine was consulted for a question of obstructive sleep apnea. cpap was recommended and this was initiated. the patient was brought to the operating room on for redo sternotomy, aortic valve replacement with st. tissue valve. overall the patient tolerated the procedure well and post-operatively was transferred to the cvicu on neo, epinephrine and propofol for further observation and invasive monitoring. the epinephrine drip was weaned off, and the patient acutely decompensated, becoming hemodynamically unstable with a metabolic acidosis. he was volume resuscitated with colloid and 4 units packed red blood cells. he was further treated with levophed, epinephrine, calcium and bicarbonate. tee was performed. atrial fibrillation ensued and he was cardioverted and subsequently paced. right femoral line was placed. the patient stabilized. he was extubated on pod 1, hemodynamics stabilized and he awoke neurologically intact. chest tubes and pacing wires were discontinued without complication. coumadin was initiated for atrial fibrillation. he progressed and was transferred to the step down floor for further recovery. he was gently diuresed toward his preoperative weight. low dose beta blockade was initiated in light of bradycardia. he was evaluated by physical therapy. by pod 7 he was cleared by dr. for discharge to rehab. medications on admission: medications on transfer: lovenox 130mg sc twice daily norvasc
