thicknesses are normal. the left ventricular cavity is severely dilated. there is mild global left ventricular hypokinesis (lvef = 45 %). overall left ventricular systolic function is mildly depressed (lvef= 45 %). 5. right ventricular chamber size and free wall motion are normal. 6. the aortic root is moderately dilated at the sinus level. the sinuses of valsalva are dilated. there is effacement of the sinotubular junction. the ascending aorta is moderately dilated. the aortic arch is mildly dilated. the descending thoracic aorta is mildly dilated. 7. the aortic valve is bicuspid. no masses or vegetations are seen on the aortic valve. there is no aortic valve stenosis. severe (4+) aortic regurgitation is seen. the aortic regurgitation jet is eccentric, directed toward the anterior mitral leaflet. 8. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. post-cpb: on infusion of phenylephrine. well-seated homograft in the aortic position with normal leaflet excursion. no ai. small hematoma at proximal end of homograft at of neoaorta. distal anastomosis has normal contour. lvef 45%. i certify that i was present for this procedure in compliance

the operating room and underwent a homograft bentall procedure using a 28mm lifenet prosthesis. please see operative note for details. postoperatively he was taken to the intensive care unit for monitoring. within 24 hours, mr. had awoke neurologically intact and was extubated. on postoperative day one, he was transferred to the step down unit for further recovery. he was gently diuresed towards his preoperative weight. the physical therapy service was consulted for assistance with his postoperative strength and mobility. he developed atrial fibrillation for which amiodarone was started with good rate control. coumadin was resumed for anticoagulation. mr. continued to make steady progress and was discharged home on postoperative day five. dr. will manage his coumadin dosing as an outpatient for a goal inr of 2.0-2.5. he will follow-up with dr. , his cardiologist and his primary care physician as an outpatient. medications on admission: spirinolactone 25mg daily
