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: no known allergies / adverse drug reactions attending: chief complaint: exertional dyspnea with stairs major surgical or invasive procedure: replacement of ascending aorta

maze procedure using a combination of the bp2 irrigated bipolar device and cryo cath. history of present illness: this is an 81 year old female with known atrial fibrillation and dilated ascending aorta. a recent ct scan in showed an increase in size, from approximately 4.5 to 6.0 centimeters. she remains asymptomatic. she denies chest and back pain. she denies palpitations, dizziness, syncope, presyncope, orthopnea, pnd and pedal edema. she does admit to some dyspnea when climbing a flight of stairs. past medical history: ascending aortic aneurysm aortic, mitral, and tricuspid valve regurgitation atrial fibrillation, s/p ablation dyslipidemia hypertension diverticulosis cataract surgery bladder suspension social history: lives with: son : etoh: rare family history: non

bruit right: none left: none pertinent results: echo: pre cpb: mild spontaneous echo contrast is seen in the body of the left atrium and left atrial appendage. no atrial septal defect is seen by 2d or color doppler. left ventricular wall thicknesses are normal. the left ventricular cavity size is normal. overall left ventricular systolic function is normal (lvef>55%). the right ventricular cavity is moderately dilated with normal free wall contractility. the ascending aorta is severely dilated. the descending thoracic aorta is mildly dilated. the aortic valve leaflets (3) are mildly thickened. there is no aortic valve stenosis. mild to moderate (+) aortic regurgitation is seen. there is no mitral valve prolapse. mild to moderate (+) mitral regurgitation is seen. moderate tricuspid regurgitation is seen with a dilated tricuspid annulus (surgeon informed). dr. was notified in person of the results. post cpb: the patient was initially a-paced and then sr, on a phenylephrine infusion. the biventricular systolic function is preserved. lvef 55% the left atrial appendage has been resected. there is a tube graft in the ascending aorta position. there is mild mr, mild tr, and mild ar. cxr: cardiomegaly and widened mediastinum are stable. moderate bilateral pleural effusions larger on the left side, unchanged from prior study allowing the difference in positioning of the patient. bilateral atelectasis, left greater than right. there is no pneumothorax or pulmonary edema. sternal wires are aligned. 03:24pm blood wbc-4.6# rbc-2.32*# hgb-7.3*# hct-21.0*# mcv-91 mch-31.5

hospital course: ms. was admitted same day surgery and was brought to the operating room for ascending aortic replacement, maze, and left atrial appendage ligation. please see operative report for further details. postoperatively she was transferred to the intensive care unit for management. she required vasodilators for blood pressure management and was placed on amiodarone for atrial fibrillation s/p maze. she remained intubated due to oxygen requirements and over the next few days was diuresed and able to be weaned from ventilation. she was able to be extubated on post operative day three but continued to require aggressive diuresis and pulmonary exercises. she was weaned down to nasal cannula and was transferred to the floor on post operative day five. chest tubes and epicardial pacing wires were removed per protocol. additionally she was started on coumadin for atrial fibrillation but had rapid rise in inr and was treated with ffp. inr trended back down after several days of no coumadin. she worked with physical therapy for strength and mobility. she continued to make steady progress and on post-op day seven she was discharged to rehab ( centre) with the appropriate medications and follow-up appointments. date coumadin dose inr 0 2.6 0 2.7 0 4.6, then 2.8 0 2.6, then 3.6 2.5 1.8 2.5 1.4 5 --- medications on admission: amlodipine 2.5 mg daily
