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: erythromycin base attending: chief complaint: dyspnea major surgical or invasive procedure: aortic valve replacement (. regent) . history of present illness: this is a 54-year-old gentleman who has otherwise been healthy and recently suffered a cerebrovascular accident with left-sided hemiparesis. this has resolved completely and the patient has been worked up thoroughly by his outside physicians. the physicians felt, based on a preoperative echocardiogram done in he had a patent foramen ovale. he has had an irregular heart rhythm, which the patient notes feeling palpitations. no record of atrial fibrillation has been documented for him. he has had an echocardiogram which shows a valve area of 1.3 cm2, and a gradient of 25 mm/hg, giving him moderate aortic stenosis with ++ aortic insufficiency. this has caused diminished exercise capacity. past medical history: hypertension copd stroke (residual left sided weakness) smoker rheumatic heart disease atrial fibrillation history of alcohol abuse prostatitis ? patent foramen ovale left foot surgery social history: works in computers. former alcoholic. smoked for 25 years. physical exam: gen: well developed, well noursihed man in no acute distress heart: irregualr rhythm, iii/vi systolic murmur lungs: clear abd: benign ext: trace edema, 2+ pulses, no varicosities pertinent results: 04:35am

hco3-27 angap-11 cxr: no acute pulmonary process identified. cxr: the previously identified left lower lobe pneumonia has been markedly improving. there is continued small right pleural effusion and patchy atelectasis in the right lung base. the lungs are clear otherwise. the patient has prior avr and median sternotomy. there is no evidence for pneumothorax is identified. ekg sinus rhythm ventricular premature complexes in bigeminal pattern diffuse nonspecific st-t wave abnormalities since previous tracing of , precordial q wave voltage less prominent and further st-t wave changes present ospital course: mr. was admitted to the on and taken directly to the operating room where he underwent an aortic valve replacement utilizing a . regent valve. postoperatively he was taken to the cardiac surgical step down unit for monitoring. on postoperative day one, mr. neurologically intact and was extubated. coumadin was started for anticoagulation. he was then transferred to the cardiac surgical step down unit for further recovery. he was gently diuresed towards his preoperative weight. the physical therapy service was consulted for assistance with his postoperative strength and mobility. as he was slow to anticoagulate on coumadin, heparin was started as a bridge until his inr became therapeutic. amiodarone was started for frequent premature ventricular and atrial contractions. toradol was started for relief of his sternal and shoulder pain. mr. developed a left lower lobe consolidation for which combivent, flovent and levofloxacin were started. zosyn was also started for better coverage. mr. was transfused 2 units of packed red blood cells for postoperative anemia with good results. mr. continued to make steady progress and was discharged home on postoperative day ten. he will follow-up with dr. , his cardiologist and his primary care physician as an outpatient. medications on admission: lisinopril aspirin discharge medications: 1. docusate
