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: decreased energy major surgical or invasive procedure: avr ( . regent mechanical) history of present illness: 55 year old man with a known childhood murmur who was echoed during a recent admission for pneumonia and found to have severe aortic stenosis. referred for avr after cath showed clean coronaries. past medical history: bicuspid aortic valve, aortic stenosis, aortic insufficiency, valvular induced cardiomyopathy, moderate pulmonary hypertension (52/23), recent pneumonia social history: last dental exam: 2 years ago lives with: fiance occupation: teamster trucker tobacco: none etoh: rarely family history: non-contributory physical exam: pulse: 82 o2 sat: 96% b/p left: 96/57

sem radiating to carotids and across precordium abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema/varicosities: none neuro: grossly intact pulses: femoral right:2+ left:2+ dp right:2+ left:2+ pt :2+ left:2+ radial right:2+ left:2+ carotid bruit right:- left:- pertinent results: conclusions pre-cpb:1. the left atrium is moderately dilated. no spontaneous echo contrast is seen in the left atrial appendage. no thrombus is seen in the left atrial appendage. 2. no atrial septal defect is seen by 2d or color doppler. 3. there is moderate symmetric left ventricular hypertrophy. the left ventricular cavity is moderately dilated. doppler parameters are most consistent with grade ii (moderate) left ventricular diastolic dysfunction. 4. right ventricular chamber size and free wall motion are normal. 5. there are simple atheroma in the descending thoracic aorta. 6. the aortic valve is bicuspid. there is severe aortic valve stenosis (valve area 0.8-1.0cm2). moderate (2+) aortic regurgitation is seen. the severity of aortic regurgitation may be underestimated. the aortic regurgitation jet is eccentric, directed toward the anterior mitral leaflet. 7. the mitral valve appears structurally normal with trivial mitral regurgitation. there is bilateral retraction of the mitral valve. 8. there is a small to moderate sized pericardial effusion. 9. a moderate left pleural effusion is seen. drs. and were notified in person of the results. post-cpb: on infusions of epi, neo. av pacing , then a pacing. well-seated mechanical valve in the aortic position. coronary flow seen in lmca and rca. trace ai consistent with washing jets. preserved ventricular function on inotropic support. lvef is now 40%. trace mr. aortic contour is normal

admitted on and underwent avr( mech avr #23 st. ) with dr. . see operative note for details. post operatively he remained intubated and was transferred to the cvicu in stable condition on epinephrine, phenylephrine, propofol, and lidocaine drips. he awoke neurologically intact, was weaned from the ventilator and extubated. vasoactive medications were weaned after hemodynamic stability was achieved. betablockers, diuretics and statin therapies were initiated and titrated. chest tubes and temporary pacing wires were removed per protocol. coumadin therpay was intiated for mechanical avr. he was evaluated and treated by physical therapy for strength and conditioning. mr. was cleared for discharge to home on pod#4 with an inr of 2.0 by dr. . medications on admission: lasix 20mg daily zocor
