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 -year-old woman with a history of aortic stenosis, presented to , hospital on , with acute onset of shortness of breath. she was found to be in new onset atrial fibrillation with resultant chf. she given diltiazem for rate control and lasix for diuresis. an echo at the outside hospital showed an ejection fraction of 53% and aortic valve area of 0.3 cm with a peak gradient of approximately 130. she was transferred on , to the cmi service in preparation for catheterization and possible valvuloplasty on . past medical history: 1. aortic stenosis, 17-18 mmhg gradient by echo with a valve area of 0.3. 2. paroxysmal atrial fibrillation. 3. retinal detachment. social history: the patient denies tobacco or alcohol use. she is a widow and lives alone. her daughter lives nearby. family history: noncontributory. medications at home: digoxin 0.125 mg p.o. q.d. allergies: penicillin and shellfish. physical examination on admission: vital signs - temperature 97.6, heart rate 87, blood pressure 102/54, breathing 21, satting at 92% on room air. she is an elderly woman in no acute distress. heent - moist mucous membranes, pupils are equal and reactive to light, extraocular muscles intact. neck exam - no jvd. cardiovascular exam - irregularly irregular, 3/6 systolic ejection murmur at the right upper sternal border, harsh in character, also a 2/6 systolic ejection murmur, blowing in character at the apex. lungs were clear bilaterally. abdomen was soft, nontender, nondistended, positive bowel sounds. extremities - 2+ dorsalis pedis pulses bilaterally without edema. she is alert and oriented x3. ekg prior to procedure normal sinus rhythm at 90, normal intervals, st elevations in v1 and 3, st depressions v4 through v6, 1, avl and lead 2. t-wave inversions v4 through v6, 1 and avl, no significant changes compared with the prior. the patient has lvh with re-polarization abnormalities and st segment changes. hospital course: on , the patient was taken to the cardiac catheterization lab, there was no significant coronary artery disease on the catheterization. the peak gradient across the aortic valve was 86 with a calculated valve area of 0.32 cm2. after the intervention, which was a balloon valvuloplasty, the peak gradient was 39 with a calculated valve area of 0.66. the patient tolerated the procedure well and was then admitted to the ccu for close monitoring of her hemodynamics and for complications after the procedure. the patient did extremely well after the procedure. within 24 hours the patient was up and moving around. she had no complications from the procedure. she had no pain or ecchymoses in her groin physical therapy saw the patient and deemed her safe for discharge to home. during this time repeat ekgs demonstrated that the patient was in normal sinus rhythm. lab data was significant for a hematocrit of 33.6, platelets of 211, bun and creatinine of 16 and 0.5 after the procedure. her coagulation studies were within normal limits. the patient was discharged on . discharge medications: digoxin 0.125, she was on this medicine on admission. the patient was also discharged on coumadin for paroxysmal atrial fibrillation. she was instructed to start this medicine the evening of . sha follow up appointment with her cardiologist on . she will also call his office on for an inr check. finally the patient was given the phone number of dr. and instructed to make an appointment with him to discuss possible valve replacement within the next two months. the patient initially expressed great reluctance about her valve repair, but she was encouraged to see dr. to discuss her options. , m.d. dictated by: medquist36 procedure: combined right and left heart cardiac catheterization coronary arteriography using two catheters insertion of temporary transvenous pacemaker system percutaneous balloon valvuloplasty diagnoses: congestive heart failure, unspecified atrial fibrillation aortic valve disorders personal history of tobacco use long-term (current) use of anticoagulants encounter for therapeutic drug monitoring 

Answer: The patient is high likely exposed to
