color doppler. left ventricular wall thicknesses and cavity size are normal. overall left ventricular systolic function normal (lvef >55%). right ventricular chamber size and free wall motion are normal. there is a (mobile) atheroma in the aortic arch. epiaortic scan shows clean site for insertion of aortic cannula and application of cross clamp. there are simple atheroma in the ascending aorta. the aortic valve leaflets are severely thickened/deformed. there is critical aortic valve stenosis (valve area 0.6 cm2). trace aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild (1+) mitral regurgitation is seen. there is no pericardial effusion. post-bypass: aortic valve prosthesis in place with mean gradient 14 mmhg. small paravalvular leak which resolved with protamine. preserved lv function. mild mitral regurgitation remains. aortic contours intact. remaining exam is unchanged. all findings dicussed with surgeons at the time of the exam. electronically signed by , md, interpreting physician 18:49 brief hospital course: transferred in and underwent preoperative evaluation.. on she was taken to the operating room and underwent aortic valve replacement, maze, and left atrial appendage ligation. see operative report for further details she received vancomycin for perioperative antibiotics since she was in the hospital preoperatively she was transferred to the intensive care unit for hemodynamic management. she awoke neurologically intact and was extubated without difficulty. beta-blocker and diuretic was initiated. on post operative day two she became confused and agitated, narcotic medications were stopped. she was treated with haldol for the confusion with improvement. coumadin was started due to maze and laa ligation. physical therapy worked with her on strength and mobility. she continued to improve and was transfer to the floor on post operative day four. cipro was started for urinary tract infection due to + leuks on urinalysis. she continued to progress and was ready for discharge to rehab ( in nh) on postoperative day six. coumadin received 3mg , 5mg , , inr increased from 1.3 to 2.3 no
