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: cardizem / pine oil attending: chief complaint: worsening shortness of breath major surgical or invasive procedure: 1. aortic valve replacement 23 mm biocor epic tissue valve. 2. tricuspid valve repair with a 30 mm contour annuloplasty ring. history of present illness: mr. is an 81 year old man with past medical history of hepatitis c virus genotype 2 with stage ii liver fibrosis (biopsy ) secondary to a blood transfusion in . he received blood transfusion after partial gastrectomy which was secondary to a benign gastric tumor. he has never been on treatment for his liver disease. in addition, he also has history of aortic stenosis, atrial fibrillation, hypertension and gout. he is not on anticoagulation for his atrial fibrillation. over the past one year, he has developed progressive shortness of breath that is now limiting his activity climbing one flight of stairs and walking to his car. he does not complain of chest pain or lightheadedness. he does have significant lower extremity edema which he started developing few months ago. he is nyha class ii for his symptoms. on echocardiogram from peak gradient across the aortic valve was 54 mmhg and the mean gradient was 39 mmhg. the calculated aortic valve area was 0.6 cm2. the rv systolic pressure was 49 the lvef was approximately 60%. there was moderate mitral regurgitation, moderate pulmonary hypertension and -atrial enlargement. he under went cath today which showed not signifcant cad but had a wedge pressure if 30. cardiac surgery was consulted for consideration for avr. past medical history: aortic stenosis hypertension, essential with heart failure chf - diastolic: nyha class iii atrial fibrillation, not currently on anticoagulation history of hepatitis c virus genotype 2 with stage ii liver fibrosis (biopsy ) secondary to a blood transfusion in after partial gastrectomy gout hematuria, remote gi bleed unknown cause no bloody stool in 2 yrs kidney stone, remote lower

spontaneous echo contrast is seen in the body of the left atrium. mild spontaneous echo contrast is present in the left atrial appendage. a definite thrombus is seen in the left atrial appendage. the thrombus is not mobile and appears laminated. no atrial septal defect is seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. regional left ventricular wall motion is normal. overall left ventricular systolic function is mildly depressed (lvef= 35-40 %). the right ventricular cavity is mildly dilated with borderline normal free wall function. the ascending aorta is mildly dilated. there are simple atheroma in the ascending aorta. there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are complex 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 (1+) mitral regurgitation is seen. moderate to severe tricuspid regurgitation is seen. the main pulmonary artery is dilated. the right pulmonary artery is dilated. there is no pericardial effusion. dr. was notified in person of the results at time of surgery. post-bypass: the patient is av paced. the patient is on no inotropes. left ventricular function is improved (lvef = 45%). right ventricular function is unchanged. there is a well-seated bioprosthetic valve in the aortic position. no aortic regurgitation is seen. there is a mean gradient of 9 mmhg at a cardiac output of 4.9 l/min. there is a tricuspid annuloplasty ring in place. no tricuspid regurgitation is seen. mitral regurgitation is unchanged. the left atrial appendage thrombus appears unchanged. the aorta is intact post-decannulation. . head ct : no acute intracranial hemorrhage or mass effect. correlate clinically to decide on the need for further workup. . head mra : 1. area of slow diffusion in the posterior aspect of the pons, just anterior to the fourth ventricle, with corresponding increased t2 flair signal representing a small subacute infarction. a punctate acute infarct is also located in the left paramedial vermis. 2. unremarkable mra examination. brief hospital course: mr. was a same day admit and was brought directly to the operating room where he underwent an aortic valve replacement and tricuspid valve repair. please see operative note for surgical details. following surgery he was transferred to the cvciu for invasive monitoring in stable condition. within 24 hours he was weaned from sedation, awoke neurologically intact and extubated. on post-op day one beta-blockers and diuretics were started and he was gently diuresed towards his pre-op weight. on post-op day two he appeared to have new onset facial droop and complained of blurred vision. neurology was consulted and he underwent a head ct. the ct showed no acute intracranial hemorrhage or mass effect. on the next day he underwent a head mra which showed a small subacute infarct. heparin and coumadin were started. he remained stable and was transferred to the step-down floor on post-op day four. he was seen by opthamology for post-operative lateral gaze and dipolpia. eye drops were recommended. he was told that if the symptoms persist he could patch either eye and follow-up with dr. . he was seen in consultation by the physical therapy service. by post-operative day six he was ready for discharge to rehab at in . follow-up
