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: penicillins attending: chief complaint: asymptomatic with severe mitral valve regurgitation major surgical or invasive procedure: mitral valve repair with posterior p2 quadrangular resection and placement of a 34 mm annuloplasty band. history of present illness: 58 y/o asymptomatic male with h/o mitral regurgitation. he has undergone serial echocardiograms which now reveal servere mitral regurgitation with enlarged left atrium. past medical history: mitral regurgitation, hypertension, hypercholesterolemia, h/o cll, mastocytosis, depression social history: disabled. quit smoking tobacco (pipe) 15 yrs ago. etoh drinks/week family history: non-contributory physical exam: vs: 68 20 140/88 5'" 222@ gen: well-appearing male in nad skin: unremarkable heent:

results: echo: pre-bypass: 1.no atrial septal defect is seen by 2d or color doppler. 2.left ventricular wall thicknesses and cavity size are normal. regional left ventricular wall motion is normal. overall left ventricular systolic function is normal (lvef>55%). 3.right ventricular chamber size and free wall motion are normal. 4.the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. 5.the mitral valve leaflets are mildly thickened. the mitral valve leaflets are myxomatous. an eccentric jet of severe (4+) mitral regurgitation is seen. 6. there is a trivial/physiologic pericardial effusion. post-bypass: 1 .a well-seated mitral annuloplasty ring is seen with normal leaflet motion and gradients (mean gradient = 4 mmhg). there is no valvular systolic anterior motion (). trivial (normal for prosthesis) mitral regurgitation is seen. 2. biventricular systolic functions is preserved. 3. aorta intact post decannulation 11:44am blood

underwent a mitral valve repair via sternotomy. please see operative note for surgical details. minimal invasive approach was abandoned following difficulty advancing necessary catheters. following surgery he was transferred to the csru for invasive monitoring in stable condition. later on op day he was weaned from sedation, awoke neurologically intact and extubated. on post-op day one he was started on beta blockers and diuretics. he was gently diuresed towards his pre-op weight. on post-op day one he was transferred to the sdu for further care. his chest tubes and epicardial pacing wires were removed per protocol. he has remained stable & is ready for discharge home. medications on admission: benicar 40mg qd, zocor 40mg qd, celexa 60mg qd, wellbutrin 150mg , risperidone qhs, benadryl
