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: adhesive tape attending: chief complaint: progressive dyspnea on exertion and fatigue major surgical or invasive procedure: aortic valve replacement (21mm st. tissue valve), coronary artery bypass graft x 2 (saphenous vein graft to diagonal, saphenous vein graft to obtuse marginal) history of present illness: 74 year old gentleman with known aotric stenosis followed by serial echocardiograms. since the new year, he has noted increasing fatigue and dyspnea. a repeat echocardiogram in revealed an aortic valve area of 1.0cm2 which was unchanged from his prior echo. a cardiac catheterization was performed which showed severe aortic stenosis, moderate aortic insufficiency, an enlarged aortic root and single vessel coronary artery disease. given the progression of his symptoms and disease, he was referred to dr. for surgical evaluation. he was orginally seen in by dr. and returns today for preadmission testing. he continues to note dyspnea on exertion and fatigue which has not changed. he denies chest pain, syncope or orthopnea. past medical history: hypertension hyperlipidemia asbestosis tia() rt arm and facial symptoms-(now resolved)
