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 very active 39-year-old male who was found to have a heart murmur in during a routine physical exam. an echocardiogram done at that time revealed a mildly dilated left ventricle with an ejection fraction of 50-55% and severe leaflet of mitral valve prolapse with 3+ mitral regurgitation. echocardiogram was repeated in , and it showed a dilated left ventricular chamber with an ejection fraction of 55% and severe mitral regurgitation with mitral valve prolapse. ett at that time was negative. cardiac catheterization done in showed normal coronaries with moderate mitral regurgitation with an ejection fraction of 44%. th returned for elective mitral valve replacement with dr. . past medical history: history of hypoglycemia. history of syncope as a child, last episode being when he was 13 years old. history of a heart murmur with mitral valve prolapse. past surgical history: anterior cruciate ligament repair on the right in . achilles tendon repair bilaterally in and also in . tonsillectomy in . medications on admission: none. allergies: no known drug allergies. social history: he is a civil engineer. he denied tobacco use. he has occasional etoh use with 3-4 beers per week. he lives with his wife and two children in , . he also denied recreational drug use. review of systems: noncontributory. physical examination: general: height 5 ft 6 in, weight 155 lbs. he was a well-defined male in no acute distress, appearing his stated age. skin was well hydrated with no rashes or lesions. heent: pupils equal, round and reactive to light. extraocular movements intact. normal mucosa. normal dentition. neck: supple. no jugular venous distention. no lymphadenopathy. no thyromegaly. no carotid bruits. chest: clear to auscultation bilaterally with no rales, rhonchi or wheezing. heart: regular, rate and rhythm. normal s1 and s2. there was a 2/6 systolic ejection murmur heard best at left sternal border. abdomen: soft, nontender, nondistended. normoactive bowel sounds. no guarding, rebound or rigidity. extremities: warm with no edema, cyanosis or clubbing. he had a well-healed scar of the right anterior cruciate ligament. no varicosities. neurological: he was alert and oriented times three. no motor or sensory deficits. cranial nerves ii-xii grossly intact. pulses: femoral 2+ bilaterally, dorsalis pedis 2+ bilaterally, right posterior tibial 2+, left posterior tibial 2+, radial 2+ bilaterally. laboratory data: the patient's electrocardiogram showed normal sinus rhythm with a rate of 74 beats per minute. all other lab work and chest x-ray were pending at pat. hospital course: the patient was admitted directly to the operating room on where he had a minimally invasive mitral valve repair with a #36 annuloplasty band. please see the or report for full details. in summary, the patient tolerated the operation well, and he was transferred from the operating room to the cardiothoracic intensive care unit. at the time of transfer, the patient had a mean arterial pressure of 76, was in normal sinus rhythm with a rate of 92. he had nitroglycerin and propofol infusions running at that time. the patient did well in the immediate postoperative period. his anesthesia was reversed. he was weaned from the ventilator and successfully extubated on postoperative day #1. the patient continued to do well, and he was transferred from the cardiothoracic surgery unit to the floor for continuing postoperative care and cardiac rehabilitation. over the next two days, the patient's activity level was increased with the assistance of physical therapy and nursing staff. on postoperative day #3, it was decided that the patient was stable and ready to be discharged to home. discharge physical examination: vital signs: temperature 99??????, heart rate 92 in sinus rhythm, blood pressure 110/60, respirations 18, oxygen saturation 95% on room air. weight preoperatively 70.5 kg, at discharge 77.9 kg. general: he was alert and oriented times three. he had a nonfocal exam. chest: clear to auscultation bilaterally. right thoracotomy site with steri-strips, open to air, clean and dry, with no erythema. cardiovascular: regular, rate and rhythm. s1 and s2 with no murmurs. abdomen: soft, nontender, nondistended. normoactive bowel sounds. extremities: warm and well perfused with no clubbing, cyanosis, or edema. right groin cannulation site with steri-strips, open to air, clean and dry. discharge laboratory data: white count 7.2, hematocrit 28.5, platelet count 113;

Answer: The patient is high likely exposed to
