 Medical Report: history of present illness: this gentleman had progressed to shortness of breath and chest tightness over a 2-month period with left arm numbness for which the patient visited his cardiologist. he had a cardiac catheterization and echocardiogram, and the patient was referred to dr. for aortic valve replacement and coronary artery bypass graft. past medical history: 1. hodgkin's disease at the age of 29. 2. status post splenectomy with radiation therapy for hodgkin's disease in and . 3. left ankle injury with repair. 4. question herniorrhaphy as a child. medications on admission: he was on no medications on admission. allergies: the patient has no known drug allergies. physical examination on presentation: on examination, his heart was in a sinus rhythm at 108 and blood pressure was 133/89. he had no jugular venous distention or thyromegaly. his neurologic examination was grossly intact with no motor or sensory deficits. his lungs were clear bilaterally. no

with no edema. he had some mild varicosities bilaterally with left greater than right. he had good femoral, dorsalis pedis, and posterior tibialis, and radial pulses. pertinent laboratory values on presentation: preoperative laboratory work revealed white blood cell count was 11.6 and hematocrit was 40.1. prothrombin time was 12.5, partial thromboplastin time was 29, and platelet count was 371,000. inr was 1. sodium was 141, potassium was 4.1, chloride was 103, bicarbonate was 23, blood urea nitrogen was 17, creatinine was 1, and blood glucose was 86. alt was 18, ast was 20, ldh was 211, alkaline phosphatase was 59, and total bilirubin was 0.3. pertinent radiology/imaging: his preoperative chest x-ray showed no evidence of pulmonary masses or nodules. no consolidations or pneumothoraces or effusions. please refer to the chest x-ray report done on . his preoperative electrocardiogram from also revealed a sinus rhythm with left ventricular hypertrophy and secondary st-t wave changes. hospital course: he was referred to dr. for aortic valve replacement. on , he underwent a coronary artery bypass graft times two with a right internal mammary artery to the posterior descending artery a left radial artery to the obtuse marginal. he had an aortic valve replacement with a 20-mm homograft, and he had repair of his atrial septal defect. please refer to the operative report. he was transferred to the cardiothoracic intensive care unit in stable condition. on postoperative day one, he was in a sinus rhythm with a blood pressure of 94/54. he was on a propofol drip, and nitroglycerin at 0.5 for his radial artery coverage, fentanyl, and neo-synephrine at 0.5. he remained intubated with coarse breath sounds. he extremities had trace edema. the plan was to wean his sedation. his postoperative laboratories revealed white blood cell count was 9.3, hematocrit was 27.1, and platelets were 242,000. sodium was 141, potassium was 4, chloride was 107, bicarbonate was 22, blood urea nitrogen was 11, creatinine was 0.8, and blood glucose was 119. his chest x-ray showed decreased lung volumes with no effusions of pneumothorax, and no congestive heart failure. an aggressive pulmonary toilet was started. the patient remained stable on his perioperative antibiotics. he had a bronchoscopy done; also done on , on postoperative day one, which showed clean airways by dr. . he was seen by case management and physical therapy when he was transferred out to the floor. he also had an electrophysiology consultation on postoperative day two. he had already been started on lopressor and amiodarone for runs of tachycardia. he also had some late night episodes which were asymptomatic but responded to 5 mg of intravenous lopressor. some were self-limiting. his tracing showed atrial fibrillation. they recommended continuing his lopressor and amiodarone and starting him on a intravenous heparin, off anticoagulation without a bolus if he could tolerate that. this was confirmed and reviewed by dr. . a-wire tracing did confirm atrial fibrillation and atrial flutter. on postoperative day two, he was in a sinus rhythm in the 80s with a blood pressure of 101/56. his oxygen saturations were 97% on face mask and nasal cannula. he was continued on amiodarone, imdur for his radial artery, albuterol, colace, zantac, and aspirin, as well as percocet for pain. his hematocrit was stable at 28.7. blood urea nitrogen was 11 and creatinine was 0.9. he was comfortable. his incision was clean, dry, and intact. amiodarone was increased to 400 mg three times per day as per recommendations, and he began to auto diurese; putting out 3.5 liters of urine in a 24-hour period. he was alert, awake, and oriented. he started his rehabilitation with physical therapy on the floor on postoperative day two. he continued to diurese on the floor. he received an amiodarone bolus in addition to his routine dosing for supraventricular tachycardia which converted him back to a sinus rhythm. on postoperative day three, his blood pressure was 107/70; in a normal sinus rhythm at 67. his diet was advanced. he also started his zantac. his creatinine rose slightly to 0.9. on postoperative day three, his chest tubes were removed. he remained on lopressor, amiodarone, and imdur, as well as his aspirin. he was comfortable. his lungs were clear bilaterally. his hematocrit rose to 30.5, and his creatinine dropped back down to 0.7. he had some trace peripheral edema and was continued with a pulmonary toilet and diuresis. his heparin drip continued. the decision was made to hold the coumadin for now, and the patient was transferred out to the floor. he continued to receive percocet for his incisional pain. he was followed by electrophysiology who suggested possibly getting an endocrine consultation given his radiation therapy and elevated thyroid-stimulating hormone with amiodarone. he was continued on his lopressor and insulin sliding-scale. his creatinine remained stable at 0.8. he was started on 3 mg of coumadin on postoperative day five while he continued his baseline intravenous heparin for anticoagulation for atrial fibrillation and atrial flutter, in addition to amiodarone boluses. endocrine recommended starting him on levoxyl 50 mcg p.o. once per day and following up with dr. as an outpatient. they also recommended that he get a yearly thyroid examination and to recheck his thyroid function tests is approximately eight weeks given his history of radiation therapy. he was seen again by case management. on postoperative day five, he continued with his anticoagulation with heparin and coumadin. his pacing wires were discontinued. he remained in atrial flutter and atrial fibrillation. his lungs were clear. his heart was regular in rate and rhythm. he had trace peripheral edema. he was in a sinus rhythm at 89 at the time of examination in the morning with a blood pressure of 126/75. on postoperative day six, he had some more bursts of atrial fibrillation in the evening and rapid atrial fibrillation in the morning which was rate controlled with lopressor. the patient was totally asymptomatic. he had a blood pressure of 134/81. temperature maximum was 100.6. his lungs were clear. he continued his anticoagulation and continued to ambulate with physical therapy. since all of the recommendations had been followed, over the next day, the patient continued to ambulate on the floor awaiting therapeutic anticoagulation. his creatinine remained stable at 0.9. his inr on postoperative day six rose to 1.2. he continued to receive percocet for pain and occasional ambien for sleep with good effect. the patient remained in house awaiting a therapeutic inr. on postoperative day seven, the patient had no events overnight. he was in a sinus rhythm at a rate of 77. his blood pressure was 94/53. oxygen saturation was 94% on room air. his heart was regular in rate and rhythm. his lungs were clear. he had trace pedal edema. his inr was 1.3, and he continued to ambulate. on postoperative day eight, the patient went back into intermittent atrial fibrillation and atrial flutter alternating with his sinus rhythm but with no complaints. his examination was unremarkable. on the day of discharge, his inr rose to 1.6. his prothrombin time was 15.8, and his partial thromboplastin time was 81.8 on heparin. discharge status: the patient was discharged to home. discharge diagnoses: 1. status post aortic valve replacement with a 20-mm homograft, and coronary artery bypass graft times two, atrial septal defect repair. 2. status post hodgkin's disease with splenectomy and radiation therapy. 3. status post left ankle surgery. 4. status post herniorrhaphy as a child. medications on discharge: (discharge
