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: peanut attending: chief complaint: ascending aortic aneurysm major surgical or invasive procedure: bentall procedure(25mm freestyle) with hemiarch replacment(26mm gelweave graft) with circulatory arrest. history of present illness: this is a 46 year old female with a longstanding heart murmur and a known bicuspid aortic valve. she has been followed with serial echocardiograms over the years with her most recent showing mild aortic stenosis and an ascending aorta of 4.7cm. she has been referred for surgery and is now admitted for same. past medical history: bicuspid aortic valve aortic stenosis/aortic insufficiency ascending aortic aneurysm gastroesophageal reflux social history: last dental exam: recently-has dental clearance lives with: alone occupation: archivist wgbh tobacco: denies etoh: glasses wine/wk family history: family history: half-sister with hocm. father died of mi at 71. mother died in her 40's -
