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: exertional dyspnea major surgical or invasive procedure: aortic valve replacement (#23mm st. tissue valve) history of present illness: mr. is a 73 year old gentleman with known history of severe aortic stenosis with complaints of progressive exertional dyspnea. most recent echocardiogram showed mean gradient of 65 mmhg, aortic valve area of 0.6cm2, and an ejection fraction of 45%. preoperative cardiac catheterization revealed minimal coronary artery disease and was notable for post-stenotic dilatation of aortic root and ascending aorta. he was admitted for aortic valve replacement. past medical history: severe aortic stenosis dilated aortic root inferior myocardial

present in compliance with hcfa regulations. the patient was under general anesthesia throughout the procedure. no tee related complications. the patient appears to be in sinus rhythm. results were personally reviewed with the md caring for the patient. conclusions prebypass no atrial septal defect is seen by 2d or color doppler. there is severe symmetric left ventricular hypertrophy. regional left ventricular wall motion is normal. overall left ventricular systolic function is low normal (lvef 50-55%). with borderline normal rv free wall function. the aortic root is moderately dilated at the sinus level. the ascending aorta is moderately dilated. 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 valve leaflets are severely thickened/deformed. there is critical aortic valve stenosis (valve area <0.8cm2). mild (1+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild to moderate (+) mitral regurgitation is seen. there is no pericardial effusion. dr. was notified in person of the results on at 830am post bypass patient is av paced and receiving an infusion of phenylephrine. biventricular systolic function is unchanged. bioprosthetic valve seen in the aortic position. leaflets move well and the valve appears well seated. the peak gradient across the valve is 22 mmhg. aorta is intact post decannulation. the tricuspid regurgitation is now mild. mild mitral regurgitation persists. i certify that i was present for this procedure in compliance with hcfa regulations. electronically signed by , md, interpreting physician 16:06 , m 73 radiology report chest (portable ap) study date of 11:34 am provisional findings impression: sp tue 3:23 pm final report type of examination: chest ap portable single view. indication: status post and ct removal. evaluate for possible pneumothorax. findings: ap single view of the chest obtained with patient sitting upright position is analyzed in direct comparison with the next preceding similar study of . during the one-day examination interval, the patient has been extubated, the ng tube has been removed. the same holds for the previously present swan-ganz pulmonary catheter and right-sided internal jugular sheath. left-sided chest tube has been withdrawn. no pneumothorax can be identified in the apical area. comparison of the chest findings demonstrates that the diaphragms are somewhat in higher position indicating shallow breathing mechanism but no evidence of new pulmonary parenchymal infiltrates or vascular congestion is seen. the lateral pleural sinuses remain free. impression: unremarkable postoperative findings. dr. brief hospital course: mr. went to the operating room and underwent aortic valve replacement (#23mm st. tissue valve) with dr.. cross clamp time= 65 minutes, cardiopulmonary bypass time= 87 minutes. please refer to dr operative report for further details. he was intubated, sedated, and on pressors to optimize hemodynamics when transported in critical but stable condition to cvicu. he awoke neurologically intact and was extubated without difficulty on the day of surgery. beta-blocker, aspirin, statin, and diuretics were initiated. all lines and drains were discontinued in a timely fashion. he continued to progress and was transferred to the step down unit for further monitoring on pod#1. physical therapy consulted for evaluation of increase in strength and mobility. the remainder of his postoperative course was essentially uneventful. he continued to progress and on pod# 6 he was cleared by dr. for discharge to home. all follow up appointments were advised. medications on admission: lantus insulin
