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, fatigue, decreased exercise tolerance major surgical or invasive procedure: aortic valve replacement (25mm st. epic tissue valve) history of present illness: the patient is an 89yo male with known aortic stenosis who has been followed by serial echocardiograms since . he has had progressive dyspnea on exertion as well as fatigue and was referred for surgical evaluation. past medical history: aortic stenosis mitral regurgitation tricuspic regurgitation

1+ radial right: 2+ left: 2+ carotid bruit right: + radiating murmur left: + radiating murmur pertinent results: pre-bypass: the right atrium is dilated. no atrial septal defect is seen by 2d or color doppler. overall left ventricular systolic function is mildly depressed (lvef= 40 %). with mild global free wall hypokinesis. the ascending aorta is moderately dilated. the aortic arch is mildly dilated. there are complex (>4mm) atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are complex (>4mm) atheroma in the descending thoracic aorta. there are three aortic valve leaflets. the aortic valve leaflets are severely thickened/deformed. there is severe aortic valve stenosis (valve area 0.8-1.0cm2). moderate (2+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. moderate (2+) mitral regurgitation is seen. the tricuspid valve leaflets are mildly thickened. moderate tricuspid regurgitation is seen. severe pulmonic regurgitation is seen. there is no pericardial effusion. post-bypass: the patient is v paced and on infusions of epinephrine and phenylephrine. biventricular function is preserved. the aortic valve has been replaced with a bioprosthesis. there is no ar. the peak gradient through the valve is approximately 14 mmhg. the aorta is intact. the pulmonary artery catheter is in good position in the proximal right pa. the previous valvular abnormalities and the remainder of the examination is otherwise unchanged. 05:20am blood wbc-6.2 rbc-3.13* hgb-9.6* hct-29.0* mcv-93 mch-30.7 mchc-33.2

cross clamp time=54 minutes. cardiopulmonary bypass time=80minutes. please refer to dr operative note for further details. he tolerated the procedure well and was transferred to the cvicu in critical but stable condition. pod#1 he was weaned off medications and extubated without difficulty. all lines and tubes were discontinued in a timely fashion. ep interrogated his ppm. mr. remained in the cvicu over the weekend for close observation. pod#3 he was transferred to the stepdown floor for further monitoring and progression. physical therapy consulted and an evaluation was done. beta-blockers were optimized. anticoagulation with coumadin was resumed for his chronic atrial fibrillation/flutter. mr. continued to progress and on pod# 6 dr. cleared him for discharge. mr. was discharged to rehab for further increase in endurance, strength, and activity. all follow up appointments were advised. medications on admission: coumadin 5mg alternating 4mg, albuterol prn, atenolol
