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: addendum to previous discharge summary dated : please see previous discharge summary for full past medical history and hospital course up until . patient was originally scheduled to be discharged to rehabilitation. however, before a bed at the rehabilitation facility could become available the patient progressed sufficiently with physical therapy to the point where she was deemed safe for discharge to home. subsequently the patient remained in the hospital for several days awaiting her inr to increase to a safe level and by postoperative day number 18 her inr had risen to 2.9 and she was cleared for discharge to home. condition at discharge: temperature maximum 97.9, pulse 76, blood pressure 108/68, respiratory rate 16, room air oxygen saturation 97 percent. neurologically the patient is awake, alert and oriented times three. her examination is nonfocal. heart is regular rate and rhythm with a sharp mild click and no murmur. respiratory: breath sounds were clear bilaterally. gastrointestinal: positive bowel sounds, soft, nontender, nondistended, tolerating a regular diet. extremities: lower extremities have bilateral varicosities. no evidence of edema. sternal incision is clean and dry. there is no erythema or drainage. chest x-ray performed on showed a small right effusion, was without evidence of infiltrate or pneumothorax. laboratory data: her pt was 21.4, her inr was 2.9. patient is to be discharged to home in stable condition. discharge diagnoses: 1. mitral stenosis, status post mitral valve replacement with a . mechanical valve. 2. tricuspid regurgitation, status post tricuspid valve repair. 3. atrial fibrillation. 4. status post maze procedure. 5. diabetes mellitus. 6. hypertension. 7. asthma. 8. hypercholesterolemia. 9. status post vvi permanent pacemaker. 10. anxiety. discharge medications: 1. colace 100 mg p.o. b.i.d 2. protonix 40 mg p.o. once daily. 3. bumex 2 mg p.o. once daily. 4. amiodarone 200 mg p.o. once daily. 5. synthroid 25 mcg p.o. once daily. 6. colchicine 0.6 mg p.o. b.i.d 7. ibuprofen 400 mg p.o. q 4 to 6 hours p.r.n. 8. coumadin. patient is to be discharged with alternating doses of 7 and 10 mg of coumadin. she is to take 7.5 mg of coumadin on . she is to have her inr checked on . if the inr is within range of 3.0 to 3.5 she is to take 10 mg coumadin on . she is also to have her inr checked on and again if the inr if sufficient she to take 7.5 mg of coumadin on . these laboratories will be followed by dr. house staff with appropriate instructions to the visiting nurse and patient is to have inr drawn on with results called to her primary care physician, . office. 9. paxil 40 mg p.o. once daily. 10. nicotine transdermal patch 7 mg patch transdermal once daily. 11. trazodone 25 mg p.o. once daily. 12. clonopin 0.5 mg p.o. once daily. 13. glyburide 5 mg p.o. once daily. 14. glucophage 500 mg p.o. b.i.d 15. lisinopril 10 mg p.o. once daily. 16. lopressor 12.5 mg p.o. b.i.d patient is to follow up with her cardiologist, dr. , in two to three weeks. she is to follow up with her primary care physician, . , by phone on for inr results and in person in two to three weeks. she is to follow up with dr. in four weeks. she is to follow up with dr. from electrophysiology service in four weeks for evaluation of her pacemaker. her coumadin follow up is as above. the inr on and will be checked by dr. house staff and on will be checked by dr. office. , m.d. procedure: continuous invasive mechanical ventilation for less than 96 consecutive hours venous catheterization, not elsewhere classified extracorporeal circulation auxiliary to open heart surgery combined right and left heart cardiac catheterization coronary arteriography using two catheters angiocardiography of left heart structures diagnostic ultrasound of heart insertion of endotracheal tube non-invasive mechanical ventilation excision or destruction of other lesion or tissue of heart, open approach open and other replacement of mitral valve systemic arterial pressure monitoring central venous pressure monitoring open heart valvuloplasty of tricuspid valve without replacement diagnoses: unspecified essential hypertension atrial fibrillation other chronic pulmonary heart diseases atrial flutter rheumatic heart failure (congestive) other and unspecified angina pectoris primary hypercoagulable state diseases of tricuspid valve mitral stenosis 

Answer: The patient is high likely exposed to
