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: the patient is a 61 year old female with a long history of mitral valve prolapse. over the last several months, she has experienced increased shortness of breath and fatigue. echocardiogram had shown progression of her mitral regurgitation at 3+ to 4+ with a left ventricular ejection fraction of approximately 25%. cardiac catheterization revealed nonobstructive coronary artery disease. elevated filling pressures with a prominent v wave are consistent with severe mitral regurgitation as seen by cardiac catheterization. the patient was counseled on the risks and benefits and, therefore, agreed to have her mitral valve repaired with a bioprosthetic mitral valve. past medical history: 1. pyelonephritis. 2. degenerative joint disease. 3. hypertension. 4. fibromyalgia. 5. chronic renal insufficiency. 6. hiatal hernia. past surgical history: 1. breast biopsy. 2. elbow surgery. 3. total abdominal hysterectomy and bilateral salpingo-oophorectomy in the past. medications on admission: hydralazine, plaquenil, premarin, desipramine, multivitamins, darvocet, zantac and ativan. laboratory data: admission chest x-ray was notable for bilateral pleural effusions. admission white blood cell count was 6, hematocrit 39 and platelet count 279,000. urinalysis was unremarkable. admission sodium was 141, potassium 3.9, chloride 99, bicarbonate 23, bun 27, creatinine 1.7, prothrombin time 12.8, and partial thromboplastin time 25.3. ho course: the patient was taken to the operating room by dr. on , where she underwent a thoracic approach with a mitral valve repair using an annuloplasty band prosthesis, serial number , model number 4600, life sciences valve. postoperatively, the patient remained intubated and was sent to the csru, where she was being maintained on levophed, milrinone and propofol secondary to her labile intraoperative pressures and labile postoperative pressures. the patient remained intubated overnight. the next morning she was transfused three units to keep her hematocrit above 26 postoperatively. her hematocrit was 35 on postoperative day number one. she was noted to have pulmonary artery pressures of 33/29 and cardiac output of 2.66 and index of 1.8. she was still being maintained with levophed and milrinone and neo-synephrine as well as a propofol drip for sedation. the plan on postoperative day number one was to wean support as long as she was hemodynamically stable. the patient's hematocrit was followed serial and she was transfused to maintain a hematocrit greater than 30. her milrinone was weaned as tolerated. given her labile pressures postoperatively, she did receive an echocardiogram on , which showed right ventricular failure and anterior wall hypokinesis. she was maintained with an intra-aortic balloon pump from into , as well as pressors. her increasing pressor requirement and balloon pump requirement was concerning, however, the patient did not sour clinically. tube feeds were started because the patient was unable to be extubated and did not tolerate this hemodynamically. her platelet count was noted to drop down to 94,000 on postoperative day number two. her bun and creatinine were 19 and 1.2, down from the admission of 1.7. her coagulation profile had a prothrombin time and inr of 14 and 1.4 and partial thromboplastin time of 34 with an ionized calcium of 1.3. the patient failed to wean to extubate until . her follow-up platelet count was noted to be 52,000 and it was thought that a medication such as zantac or heparin or the balloon-pump, etc, or an indwelling catheter, such as the swan-ganz catheter, may be contributing to her thrombocytopenia. therefore, all of the potentially inciting medications were discontinued. her balloon-pump was discontinued after five packs of platelets were transfused. a hit panel was sent for analysis that ultimately returned as positive. by postoperative day number three, the patient was neurologically stable and alert. she was on percocet for pain. a chest x-ray showed large bilateral effusions. her milrinone and hydralazine were discontinued and she was started on lopressor. nipride was weaned as tolerated. she was given albumin and lasix as well. she was started on a diet with supplements. by postoperative day number four, the patient was noted to be somewhat confused and agitated. it was felt to be secondary to mild intensive care unit psychosis. she was not hypoxic or severely volume depleted in any way or over-medicated. the patient was discharged to the floor with a sitter. she was started on hydralazine 10 mg every six hours as well as aspirin. her swan-ganz catheter was moved to central venous pressure. on postoperative day number five, the cordis was removed and the patient had a peripheral intravenous line placed. her pacing wires were removed. physical therapy and rehabilitation screening began. the patient was tolerating a diet and ambulating in the hallway. her pain was being controlled. she was voiding spontaneously and reported a bowel movement. the chest tube, however, continued to have moderate to high output and was therefore maintained until postoperative day number eight, when it was discontinued. a follow-up chest x-ray showed bilateral pleural effusions with no pneumothorax. the effusions were stable, if not improved. ultimately, the patient was slated for discharge to a rehabilitation facility the following day, on postoperative day number nine. she is stable and doing well. her discharge examination is noted for a stable sternum with clean, dry and intact wound with steri-strips. she has a dressing over the superior abdomen, the site of her previous wire and chest tube insertion sites, which can be removed two days after discharge. the patient's heart is regular. she has decreased breath sounds at the bases bilaterally, no crackles. abdomen is benign. extremities are warm and well perfused with normal pulses. condition on discharge: stable. discharge status: the patient is being discharged to a cardiac rehabilitation facility. discharge diagnosis: history of mitral valve prolapse with severe mitral regurgitation and left ventricular ejection fraction of 30%, status post mitral valve repair #26 ce rim, complicated by postoperative right ventricular failure and anterior wall hypokinesis requiring intra-aortic balloon pump resuscitation; currently, patient is stable, afebrile and appropriate for discharge to a rehabilitation facility. , m.d. dictated by: medquist36 procedure: extracorporeal
