and a soft carotid bruit on the left and 1+ on the right. hospital course: he was admitted as a same-day admission on and underwent mitral valve replacement with a 27- mm - pericardial valve by dr. . he was transferred to the cardiothoracic icu in stable condition on an epinephrine drip at 0.02 mcg/kg/min, a nitroglycerin drip at 0.5 mcg/kg/min, and a propofol titrated drip. on postoperative day 1, he had been extubated overnight. he had some short bursts of afib, but was in sinus rhythm in the morning at 73 with a blood pressure of 123/48. postop labs as follows: k of 6.0, bun of 16, creatinine of 0.9, white count of 16.7, pt of 14.3, with an inr of 1.4. he began lopressor beta blockade and lasix diuresis. he was alert and oriented, and his exam was otherwise unremarkable; and he was transferred out to the floor in stable condition on an insulin drip in the morning of 0.5 units per hour. on postoperative day 2, his chest tubes were discontinued. he had a 10% right apical pneumothorax, from which he was not symptomatic post chest tube pull. he was in first-degree av block at a heart rate of 65, maintaining good blood pressure. he continued his perioperative antibiotics; was restarted on his synthroid and other cardiac medicines. his central venous line was removed. pacing wires remained in place. he was alert and oriented with an unremarkable exam. a cardiology consult was requested for evaluation of his atrial tachycardia and first-degree av block. their recommendation was to continue his beta blocker and continue to monitor. he remained alert and oriented in his 2:1 av block over the course of the first 2 days. he started to work with the nurses and physical therapists on increasing his activity level and endurance. on postoperative day 3, his chest tubes had been removed. he was encouraged to ambulate and to increase his activity level. he was transfused 1 unit of packed red blood cells for a low hematocrit, but remained hemodynamically stable as his heart rate rose to the 70s. on postoperative day 4, he went back and forth between sinus bradycardia and wenckebach rhythm. at that point ep consult recommended discontinuing his lopressor. he went into atrial fibrillation that morning with a ventricular response rate of 57 and a systolic blood pressure of 107; was seen by dr. of electrophysiology. the patient went back into sinus rhythm overnight on postoperative day 5; and heparin, which had been started, was stopped. on the 17th, the patient was in sinus rhythm in the 80s; and cardiology reevaluated the patient again as he appeared to be somewhat stable, in sinus rhythm at 80s to 90s with occasional first-degree av block. on postoperative day 6, he was back in atrial fibrillation but maintaining a good blood pressure of 127/58. heparin was restarted, and first dose of coumadin was given of 2 mg later that afternoon for coverage of his atrial fibrillation. his lung sounds were slightly coarse. his heart was irregular, but he remained hemodynamically stable. pacing wires remained in place. on postoperative day 7, he remained in atrial fibrillation. pacing wires were discontinued. discharge planning was begun, and he was restarted on lopressor 12.5 mg p.o. b.i.d. he had some hyperkalemia with a k of 6.0. kayexalate was given, and kcl was discontinued with his lasix therapy. on postoperative day 8, he received a second dose of 5 mg of coumadin with plans that when his inr crossed 1.5 he would be able to discharge home with vna services. beta blockade was increased as tolerated. his inr was 1.3 on postoperative day 8. his sternum was stable. he went back into sinus rhythm and then back to atrial fibrillation on the day of discharge - - with an inr of 1.8 on coumadin therapy. discharge status: he was discharged to home in stable condition. his blood pressure was 115/55, respiratory rate of 20, heart rate of 67, ventricular rate response, in atrial fibrillation, weight of 73.2 kilograms, saturating 98% on room air. discharge disposition: he was discharged to home with vna services on . discharge diagnoses: 1. status post mitral valve repair with a 27-mm pericardial valve. 2. coronary artery disease;

to see dr. in approximately 2 weeks; and to return to our clinic at in 2 weeks. the patient was again instructed to have inr checked by vna on , , and call results to dr. office () for further coumadin dosing. condition on discharge: he was discharged on in stable condition. , m.d. procedure: extracorporeal circulation auxiliary to open heart surgery diagnostic ultrasound of heart open and other replacement of mitral valve with tissue graft transfusion of packed cells diagnoses: hyperpotassemia pure hypercholesterolemia mitral valve disorders congestive heart failure, unspecified unspecified acquired hypothyroidism atrial fibrillation percutaneous transluminal coronary angioplasty status occlusion and stenosis of carotid artery without mention of cerebral infarction iatrogenic pneumothorax asbestosis profound impairment, one eye, impairment level not further specified neurofibromatosis, unspecified
