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: mr. is a 57-year-old male who had an abnormal ekg which ultimately lead to work up including cardiac catheterization, transthoracic echocardiogram and a ct scan ultimately showing a bicuspid aortic valve with aortic regurgitation and an ascending thoracic aneurysm with secondary left ventricular hypertrophy. th has never had any chest pain, shortness of breath or dyspnea. no history of congestive heart failure or palpitations. no lower extremity edema. no prior history of mi or cva. no diabetes in the past. cardiac catheterization data was unavailable at initial presentation as a resultant fax to dr. office. past medical history: 1. he has no prior surgical history. 2. he had a heart cath 18 years ago for a "congenital disease" which is not otherwise specified. 3. benign heart murmur for which he gets prophylaxis with antibiotics over his lifetime. 4. no history of major depression and anxiety. 5. no hypertension. 6. he is on accupril for his aortic insufficiency. 7. no history of coronary artery disease. he has clean coronaries by recent preoperative cardiac catheterization. 8. no history of gastroesophageal reflux disease. 9. no history of dyslipidemia or diabetes. outpatient medications: 1. paxil 20 mg p.o. q. day. 2. accupril 10 mg p.o. q. day. 3. multivitamin occasionally. 4. he is not taking any aspirin. his cardiologist is dr. at the in , . dr. is his pcp in the region. allergies: he has no known drug allergies except for just some seasonal allergies. last dental exam was done on which showed no evidence of caries or risk. no need for tooth extraction. family history: he has a son who has a prior history of repair with aortic aneurysm resection. his son has a history of congenital bicuspid aortic valve which related in aortic stenosis which required his procedure. social history: patient's occupation is a probation officer. he lives with his wife. has three grown children. uses minimal alcohol. only tobacco history was that of cigars. physical examination: in general well appearing, active, well-nourished, well-developed, age appropriate male. no rashes were present on the skin. head, eyes, ears, nose and throat: pupils are equal, round and reactive to light and accommodation. extraocular muscles intact. no jugular venous distention, no bruit. no cervical lymphadenopathy. his precordium was quiet. lungs were clear. abdomen was soft. extremities were unremarkable. neurological is nonfocal. ese findings, he was sent for evaluation by dr. who deemed the patient an appropriate candidate for aortic valve replacement as well as resection of the ascending aortic aneurysm and the non-coronary sinuses. on , the patient was admitted to the hospital and went to the operating room where he underwent an aortic valve repair with a 27 mm - pericardial tissue valve. also had resection of an ascending aortic aneurysm and of the non-coronary sinus. a 26 mm tube graft was accordingly placed. dr. was then attending surgeon with dr. being the assistant. the patient pericardium was left open with a right radial a line and right ij swan-ganz catheter, two ventricular and two atrial pacing wires. there was mediastinal and right pleural tubes that had been placed. he was in sinus rhythm. he came off the pump without any difficulty. postoperatively he was rapidly extubated. he did well from a hemodynamic standpoint. he had excellent blood pressure control. strips were weaned the following day and started on an oral regimen of lopressor. he was diuresed accordingly. he otherwise is out of bed ambulating. he was transferred to the floor. his wires were removed. his foley catheter had been discontinued. he is tolerating a diet ultimately by postoperative day #3. the patient passed a level 5 ambulatory status after having completed stairs without any assistance. the patient was eager to actually go home. given the fact that he had done markedly well postoperative, his wounds looked excellent, lungs were clear, lower extremities were not edematous and the fact that he asked for analgesia and was ambulating up stairs without difficulty, it was thought that the patient was appropriate for discharge to home without service. medication on discharge: 1. paroxetine 20 mg p.o. q. day. 2. percocet one to two tabs p.o. q. four to six p.r.n. 3. ibuprofen p.r.n. 4. tylenol as needed. 5. aspirin 325 mg p.o. q. day. 6. lasix 20 mg p.o. b.i.d. times seven days. 7. k-dur 20 meq p.o. b.i.d. to be taken for the seven days that he is on lasix. 8. lopressor 12.5 mg p.o. b.i.d. 9. accupril will be held until he is seen by dr. at follow up in the . 10. continue his multivitamins. discharge disposition: will be sent home without services. he did well postoperatively and had no other issues to speak of. , m.d. dictated by: medquist36 d: 10:29 t: 11:39 job#: procedure: extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart open and other replacement of aortic valve with tissue graft resection of vessel with replacement, thoracic vessels diagnoses: anxiety state, unspecified congenital insufficiency of aortic valve thoracoabdominal aneurysm, without mention of rupture cardiomegaly personal history of affective disorders 

Answer: The patient is high likely exposed to
