saphenous vein single graft from the aorta to the first diagonal coronary artery. history of present illness: 76 year old male with severe aortic stenosis who has been followed by dr. . an echo over the summer demonstrated severe aortic stenosis. since the summer he has noted almost nightly pnd and chest pressure. he goes to sleep without a problem, usually with only one pillow, and then wakes up with chest pressure. he then sleeps the rest of the night in a chair. he also notes occasional lightheadedness when he stands up to quickly or with bending over. he occasionally feels "fluttering" in his chest which last a moment. was referred for a cardiac catheterization to further evaluate. he is now being referred to cardiac surgery for an aortic valve replacement and revascularization. past

seen by 2d or color doppler. there is mild symmetric left ventricular hypertrophy. regional left ventricular wall motion is normal. overall left ventricular systolic function is normal (lvef>55%). right ventricular chamber size and free wall motion are normal. there are simple atheroma in the ascending aorta. there are simple atheroma in the descending thoracic aorta. the aortic valve leaflets are severely thickened/deformed. there is severe aortic valve stenosis (valve area 0.8-1.0cm2). mild to moderate (+) aortic regurgitation is seen. the mitral valve leaflets are mildly thickened. mild to moderate (+) mitral regurgitation is seen. there is no pericardial effusion. dr. was notified in person of the results on at 900 am. postbypass: the patient is in sinus rhythm on low dose phenylephrine infusion. there is a well seated bioprosthetic valve in the aortic position. there is no ai. the peak and mean gradients across the valve are 18mmhg & 7mmhg, respectively. the biventricular function is maintained. the remaining valves are unchanged. the aorta remains intact. . chest x-ray: the patient is status post median sternotomy, coronary bypass surgery and aortic valve replacement procedure. cardiomediastinal contours are within normal limits. improving atelectasis and effusion at left lung base. right lung and pleural surfaces are clear except for minimal linear atelectasis at the right base. small air-fluid level is present in the retrosternal region. it may reflect a small anterior loculated hydropneumothorax or postoperative changes in the retrosternal region related to recent sternotomy. . wbc-8.3 rbc-3.19* hgb-10.0* hct-29.3 plt ct-225# wbc-7.1# rbc-3.70*# hgb-11.7*# hct-33.1 plt ct-226 urean-34* creat-1.1 na-142 k-4.3 cl-101 urean-20

stable condition. within 24 hours he was weaned from sedation, awoke neurologically intact and extubated. on post-op day one he was started on beta-blockers and diuretics and diuresed towards his pre-op weight. chest tubes and epicardial pacing wires were removed per protocol. on post-op day two he was transferred to the step-down floor for further care. he worked with physical therapy for assistance with strength and mobility. he continued to make good progress and on post-op day 5 he was discharged home with homecare services and the appropriate medications and follow-up appointments.
