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 major surgical or invasive procedure: mitral valve replacement, cryomaze procedure and left atrial appendage resection history of present illness: 72 y/o female with known mitral regurgitation who was referred for surgical intervention. past medical history: mitral regurgitation, atrial fibrillation h/o cardioversion, hypertension, chronic obstructive pulmonary disease, hodgkin's disease s/p chemo, squamous cell cncer right calf s/p excision, hypothyroidism, s/p hysterectomy, s/p c-section and appendectomy, s/p lumbar disc surgery social history: denies tobacco use. occasional etoh. lives with husband. family history: non-contributory

soft, nt/nd +bs ext: warm, well-perfused 1+ pedal pulses, -varicosities neuro: mae, non-focal, a&o x 3 pertinent results: echo : prebypass: left ventricular cavity size, and systolic function are normal (lvef>55%). intrinsic function is probably depressed in the setting of moderate mitral regurgitation. there is mild left ventricular hypertrophy. there are complex (>4mm) atheroma in the descending thoracic aorta. the aortic valve leaflets (3) are mildly thickened. there is no aortic valve stenosis. mild (1+) aortic regurgitation is seen. the mitral valve leaflets are myxomatous. there is moderate/severe mitral valve prolapse of the anterior and posterior mitral leaflets.. moderate (2+) mitral regurgitation is seen. the mitral regurgitation jet is eccentric. there are multiple eccentric jets seen. significant pulmonic regurgitation is seen. post bypass: biventricular systolic function is preserved. bioprosthetic valve seen in the mitral position. valve appears well seated. leaflets move well. no mitral regurgitation detected. mean gradient across the bioprosthetic valve is 2 mmhg. aorta appears intact post decannulation. cxr : there is small left pneumothorax on the left apex that is stable compared to the previous study. there is also a small right pneumothorax at the right lung apex that is not well seen on the previous study. there is left subclavian cv line with its tip in distal third svc. there is prosthetic mitral valve that is stable compared to the previous study. there is left pleural effusion stable compared to previous study. heart size is mildly enlarged. mediastinal and hilar contours are normal. 02:00pm blood wbc-6.9 rbc-3.81* hgb-11.7* hct-32.9* mcv-86 mch-30.8 mchc-35.7* rdw-15.1 plt ct-246 05:40am blood wbc-9.4 rbc-3.23* hgb-9.9*

she was started on heparin. on she was brought to the operating room where she underwent a mitral valve replacement and maze procedure. please see operative report for surgical details. following surgery she was transferred to the csru for invasive monitoring in stable condition. later on op day she was weaned from sedation, awoke neurologically intact and extubated. she was weaned off all drip and started on beta blockers and diuretics. on this day she had several episodes of bradycardia and beta blockade was temporarily held. on post-op day two she appeared to be doing well and was transferred to the sdu. chest tubes were removed on this day and epicardial pacing wires on post-op day three. coumadin and amiodarone were restarted but she remained in sinus rhythm. physical therapy followed patient during entire post-op course for strength and mobility. she continued to improve quite well and was discharged home with vna services and the appropriate follow-up appointments on post-op day four. medications on admission: premarin, synthroid, atenolol, cozaar, coumadin, folate, aspririn, amiodarone discharge medications: 1. potassium chloride 10 meq capsule, sustained release
