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 an 88 year old female with 4+ tricuspid regurgitation, atrial fibrillation, recently admitted to from through for increased shortness of breath, dyspnea on exertion. the patient was not diuresed at this time as by laboratory data she was dry, prerenal. she diuresed 2 liters on her own. the patient was discharged to follow up with her primary care physician as her shortness of breath improved, status post 2 liters diuresis. the patient states that over the last two to three days lasix has not been effective and notes decreased urine output during the daytime and increased abdominal swelling and lower extremity edema, increasing shortness of breath, decreased energy times one week and is now reliant again on her walker. the patient denies palpitations. she denies chest pain. she denies dietary changes. she denies urgency but has decreased urine output. past medical history: atrial fibrillation, 4+ tricuspid regurgitation following polyps, status post fall and rotator cuff injury, hypertension, urinary retention. home medications: lasix 40 b.i.d.; coumadin 2 q.h.s.; lopressor 25 t.i.d.; losartan 50 q. am; fosamax one tablet q. sunday; synthroid 75 mcg q.d.; magnesium oxide 400 q. am. allergies: question of intolerance to ace inhibitors. physical examination: temperature 95.2, blood pressure 132/66, heartrate 92, respiratory rate 20. oxygen saturation 90% on room air. general, the patient is in no acute distress, alert and oriented times three. short of breath with standing. she is talking. head, eyes, ears, nose and throat, pupils equal, round and reactive to light, extraocular movements intact, jugulovenous distension to earlobe. heart, irregularly irregular, ii/vi systolic ejection murmur. loud s3. lungs, bibasilar crackles, left greater than right. abdomen soft, distended, tympanitic, hepatomegaly 3 cm below the costal margin. chest x-ray 2 to 3+ pitting edema bilaterally. laboratory data: the patient's sodium was 126, creatinine 1.6 from a baseline of 1.4. hospital course: the patient was admitted to on . the patient was initially admitted to internal medicine service, dr. where she was treated medically for her condition. she was given lasix, nitracor, sodium-restricted diet. she was continued on lopressor and coumadin. cardiology and congestive heart failure services were consulted. the patient initially experienced an improvement in her congestive heart failure, diuresing fluid fairly efficiently with her medication regimen. she was loaded on amiodarone for her atrial fibrillation. a new echocardiogram was performed which indicated severe pulmonary hypertension. she had mild aortic regurgitation and mitral regurgitation and indicated severe tricuspid regurgitation. it was then decided to consult the cardiothoracic surgery service for possible surgical intervention. her coumadin was at that time stopped. the patient had a urinary tract infection. she was ciprofloxacin 500 mg q.d. times seven days. the patient was sent for cardiac catheterization which showed tricuspid regurgitation 4+ and right-sided heart failure. the patient was seen by the vascular service over the course of her stay after an ultrasound showed a small pseudoaneurysm at the site of cardiac catheterization. vascular recommended that the groin be closely watched in the operating room for hematoma formation or expansion, otherwise not to intervene surgically or fibrin injection. the patient was transfused a unit of red blood cells for an anemia. the patient was allowed to recover from her urinary tract infection presurgical intervention and on , the patient was taken to the operating room where a tricuspid valve replacement with a 29 mm mosaic was performed. the patient appeared to tolerate the procedure well and was transferred to the cardiac intensive care unit for close monitoring postoperatively. postoperatively she was visited by vascular who were pleased by the lack of evidence for expansion of her right groin pseudoaneurysm. the patient received vancomycin postoperatively. when stable the patient was transferred to the regular cardiac floor for continued monitoring and continued pharmacologic diuresis. she was closely followed by the cardiac heart failure service. a number of pharmacological agents were used including nitracor, lasix were used. the patient was restarted on coumadin. she was treated with beta blockers. the patient was seen and treated by physical therapy. over the last few days of the patient's stay in the hospital she waited for therapeutic coumadin levels with appropriate inr levels for atrial fibrillation. she also continued rigorous diuresis managed by the congestive heart failure team and finally on the patient seemed to be ready to be discharged to rehabilitation both per congestive heart failure service and the cardiothoracic surgery service. the patient is therefore now being discharged to rehabilitation on . condition on discharge: she is in good condition. follow up: she is to follow up with dr. in four weeks, her primary care physician in one to two weeks and the cardiologist in two to three weeks, congestive heart failure team. medications on discharge: the nitracor will be discontinued. her lasix will be discontinued. she will be started on bumex 1 mg p.o. b.i.d. she will be restarted on losartan 25 mg q.d. she will also be sent home on 4 mg of warfarin q.d., polysaccharide iron complex 150 mg p.o. b.i.d., lopressor 50 mg p.o. b.i.d., levothyroxine 75 mcg p.o. q.d., percocet 1 to 2 tablets p.o. 4 prn pain, potassium chloride 20 meq p.o. q. 12 to be held for a potassium greater than 5. ranitidine 950 mg p.o. b.i.d., colace 100 mg p.o. b.i.d. discharge instructions: the patient may shower although she should not take baths. the patient should observe a heart-healthy diet. she should not drive on pain medications. , m.d. dictated by: medquist36
