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: history of present illness: this is a 41 year-old gentelman who underwent an aortic valve replacement in for endocarditis. following that procedure the patient had a repeat bout of endocarditis and had to have the replacement valve removed and a new one inserted. the patient's first aortic valve replacement was done with a bioprosthetic valve. then in the patient's repeat avr was done with a carbomedics valve. over the last couple of years the patient has been followed by serial echocardiograms where it has been noticed that his aortic root has gradually been dilating. currently his aortic root is approximately dilated at 5.8 cm with 1+ mitral regurgitation and 3+ tricuspid regurgitation, and mild pulmonary hypertension. the patient was admitted for a repeat aortic valve replacement. the patient was admitted and underwent an aortic valve replacement surgery on . a #23 st. jude valve was placed and a graft was placed on the ascending aorta. the cross clamp time was 144 minutes. the procedure was performed by dr. and he was assisted by dr. . there were no complications during the case and the patient tolerated the procedure well. following a brief stay in the pacu the patient was transferred to the csru still sedated on a propofol drip. the patient was also on a nitroglycerin drip, which was titrated to maintain his systolic blood pressure between 100 and 110. the nitroglycerin drip was weaned as tolerated. postoperative day number one the patient had three chest tubes in place. on postoperative day number one the patient had his ta line and a line removed. the nitroglycerin drip was continued to be weaned as tolerated. the patient was extubated without difficulty and was able to maintain his o2 saturations greater then 95% on nasal cannula. the patient's postoperative course was complicated by development of compartment syndrome following the surgery. vascular surgery was consulted and it was determined that the patient needed to be returned to the operating room to open up the patient's left calf. the patient underwent a fasciotomy on by vascular surgery dr. . there were no complications during the surgery and the patient tolerated this without difficulty. the final procedure was a left lower extremity anterior, posterior, lateral compartment fasciotomies. the patient was continued to be weaned off all of his pressors and he was able to maintain his blood pressure. the patient still had his av wires attached, but was able to remain in normal sinus rhythm without any ectopy. on postoperative day number two the patient had his dc pacing wires removed and the patient was started on coumadin for anticoagulation. the patient's left lower extremity continued to decrease in size and no longer complained of any pain at that site. the patient was seen by renal consult for an increase in creatinine. the patient's creatinine had risen range of motion 1.0 to 1.5 over the course of one day. it was determined that the patient was most likely experiencing some rhabdomyolysis, which caused the creatinine to increase. recommendations from renal included transfusion if the patient's hematocrit dropped to less then 30 and to hold off on any aggressive intravenous fluid or bicarb replacement. by postoperative day number three it was determined that the patient was well enough to be transferred out of the csru to the surgical floor. when the patient reached the floor he continued to have a relatively uneventful recovery. the patient was seen and evaluated by physical therapy who determined that the patient would be able to be discharged to home following a few sessions with the physical therapist. the patient's postoperative course on the floor was complicated only by increase in his white blood cells. the patient's white blood cell count increased from approximately 13 to 20. the patient was seen and evaluated by infectious disease. multiple blood cultures, urine cultures, chest x-rays were performed. all of these came back negative. the patient never spiked a fever nor had any clinical indication of any infection. the patient underwent a ultrasound of the cannulation site in his left groin, which demonstrated a small hematoma. as there was no fluctuance, erythema or pain surrounding the site this was determined not to be the course of the patient's elevated white blood cell count. the patient was continued to be followed for several days and his white blood cells were monitored. the patient continued to not exhibit any indications of a systemic illness and the patient's white count decreased to 13. at this point as the patient had been cleared by physical therapy and no obvious source of infection had been discovered it was determined that the patient was well enough to be discharged to home. die disposition: the patient will be discharged to home and asked to follow up with dr. in four weeks. in addition, the patient was instructed to follow up with the clinic for which he follows his inr levels. the patient was also instructed to follow up with dr. in one to two weeks and his cardiologist in two to three weeks. the patient was asked to please schedule these appointments. discharge diagnoses: 1. status post aortic valve replacement with a st. jude valve. 2. status post avr times two. 3. status post fasciotomy left lower extremity. 4. status post ascending aortic graft replacement. 5. hypertension. discharge medications: 1. metoprolol 100 mg po b.i.d. 2. colace 100 mg po b.i.d. 3. lasix 20 mg po b.i.d. for seven days. 4. potassium chloride 20
