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 major surgical or invasive procedure: - right thoracotomy (minimally invasive approach), redo mitral replacement (29mm st. mechanical ) history of present illness: this is a 61-year-old male who had a mitral repair done 5 years ago which consisted of an annuloplasty ring trade. he developed severe mitral regurgitation recently and it was recommended that he undergo replacement of his mitral . the risks and benefits were explained to him and he has agreed to proceed. past medical history: hyperlipidemia lower back

echo pre cpb: the left atrium is normal in size. no mass/thrombus is seen in the left atrium or left atrial appendage. no atrial septal defect is seen by 2d or color doppler. left ventricular wall thicknesses and cavity size are normal. overall left ventricular systolic function is low normal (lvef 50-55%). right ventricular chamber size and free wall motion are normal. the ascending, transverse and descending thoracic aorta are normal in diameter and free of atherosclerotic plaque. there are simple atheroma in the ascending aorta. there are simple atheroma in the aortic arch. there are simple atheroma in the descending thoracic aorta. the aortic leaflets (3) appear structurally normal with good leaflet excursion and no aortic regurgitation. trace aortic regurgitation is seen. the mitral leaflets are mildly thickened. there is moderate/severe mitral prolapse. a mitral annuloplasty ring is present. there is no systolic anterior motion of the mitral leaflets. severe (4+) mitral regurgitation is seen. the mitral regurgitation jet is eccentric. the tricuspid leaflets are mildly thickened. moderate tricuspid regurgitation is seen. there is no pericardial effusion. post cpb: well-seated mechanical in the mitral position. trace mr discs. trivial paravalvular or stitch leak that is not visible after protamine administration . ai is trace and verified by dr. . normal biventricular systolic function on phenylephrine drip. 2+ tr, trace pi as described. cxr endotracheal tube has been removed, but there has been no appreciable change in lung volumes. moderate degree of atelectasis at both lung bases, more severe on the right, has improved on the left. upper lungs are clear. widening of the postoperative cardiomediastinal silhouette has improved. there is no appreciable pleural effusion or any indication of pneumothorax. right pleural tubes are in standard placements. tip of the swan-ganz catheter projects over the bifurcation of the pulmonary artery. ospital course: mr. was admitted to the on for elective surgical management of his mitral regurgitation. he was taken directly to the operating room where he underwent a mini right thoracotomy with a redo mitral replacement utilizing a 29mm st. mechanical . postoperatively he was taken to the cardiac surgical intensive care unit for monitoring. by postoperative day one, mr. had awoke neurologically intact and was extubated. his drains were removed and he was transferred to the nursing floor for further recovery. mr. was gently diuresed towards his preoperative weight. heparin as a bridge to coumadin was started for anticoagulation. the physical therapy service was consulted for assistance with his postoperative strength and mobility. mr. was slow to reach a therapeutic inr however by postoperative day six, he was within range. he was thus discharged home and will follow-up with dr. , his cardiologist and his primary care physician as an outpatient. on discharge, his wound was clean, dry and intact and his vitals signs were stable. medications on admission: aspirin 81mg daily lipitor 20mg daily lisinopril 5mg daily toprol xl 37.5mg twice daily discharge
