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: dypsnea on exertion major surgical or invasive procedure: aortic valve replacement(. regent mechanical valve) history of present illness: this is a 81 yo female with severe aortic stenosis followed by serial echos. she complains of dyspnea on exertion and displays class iii heart failure. most recent echo showed 0.5 cm2. cardiac cath showed 70% diagonal lesion. based upon the above, she was referred to dr. for cardiac surgical intervention. past medical history: aortic stenosis hypercholesterolemia type ii diabetes mellitus hypertension obesity osteoarthritis pulmonary nodules social history: quit tobacco 25 years ago. occasional etoh. lives with husband. family

10:51am blood mg-2.5 chest x-ray: when compared to prior studies dated and , bilateral small pleural effusions, greater on the left side, have slightly increased in amount. left perihilar and left lower lobe retrocardiac atelectases are unchanged. left cardiac border is obscured by the pleural and parenchymal abnormalities. right internal jugular vein catheter tip is in unchanged position in the svc. there is no pneumothorax. intraop tee: pre-bypass: 1. no atrial septal defect is seen by 2d or color doppler. 2. there is moderate symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. overall left ventricular systolic function is mildly depressed (lvef= 40 %). 3. right ventricular chamber size is normal. 4. there are complex (>4mm) atheroma in the ascending aorta. the descending thoracic aorta is mildly dilated. there are complex (>4mm) atheroma in the descending thoracic aorta. 5. there are three aortic valve leaflets. the aortic valve leaflets are severely thickened/deformed. there is severe aortic valve stenosis (area <0.8cm2). moderate (2+) aortic regurgitation is seen. 6. the mitral valve leaflets are moderately thickened. there is severe mitral annular calcification. mild to moderate (+) mitral regurgitation is seen. 7. the tricuspid valve leaflets are mildly thickened. 8. the pulmonic valve leaflets are thickened. 9. there is a small pericardial effusion. post-bypass: 1. biventricular systolic function is unchanged. 2. mechanical valve seen in the aortic postion. leaflets move well and the valve appears well seated. washing jets seen. 3. mild mitral regurgitation present. 4. aorta intact post decannulation. brief hospital course: admitted and underwent avr with dr. . transferred to the csru in stable condition on phenylephrine and propofol drips. extubated the next day and transferred to the floor on pod #2 to begin increasing her activity level. went into a fib on pod #2 and treated with amiodarone. coumadin also started for her mechanical valve and dosed for a goal around 2.5 to 3.0. chest tubes and pacing wires were eventually removed without complication. by pod#3, she converted back to a normal sinus rhythm. she maintained a normal sinus rhythm for the remainder of her hospital stay. no further episodes of atrial fibrillation were noted. over several days, she continued to make clinical improvements with diuresis and was medically cleared for discharge to home on . following discharge, she is to get a follow-up ct scan of the chest in 6 months for bilateral pulmonary nodules. dr. office has been notified of this finding. dr. will also monitor coumadin as an outpatient. medications on admission: lisinopril 20 mg/hctz 12.5 mg daily ecotrin 325 mg daily glipizide 2.5 mg daily
