varicosities neuro: a&ox3, non-focal, mae pertinent results: cardiac cath: lmca heavy calcification with distal taper 30%, lad origin 95% heavily calcified lesion, distal lad is a good target, lcx with origin 60% calcified lesion, rca with modest diffuse calcification. echo: pre-bypass: a patent foramen ovale is present. a left-to-right shunt across the interatrial septum is seen at rest. regional left ventricular wall motion is normal. overall left ventricular systolic function is low normal (lvef 50-55%). right ventricular chamber size and free wall motion are normal. there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are complex (>4mm)atheroma in the descending thoracic aorta. there are three aortic valve leaflets. there is no aortic valve stenosis. mild to moderate (+) aortic regurgitation is seen. the aortic regurgitation jet is eccentric. mild (1+) mitral regurgitation is seen. post-bypass: pt is being a paced and is on an infusion of phenylephrine. biventricular systolic function is preserved. other findings are unchanged cxr: small bilateral pleural effusion has increased. mild enlargement of the postoperative cardiomediastinal silhouette is stable. there is no pneumothorax. lungs clear. small collection of retrosternal gas and fluid at the level of the sternal angle is a common postoperative finding, but not necessarily pathologic. 10:15am blood wbc-3.4* rbc-4.05* hgb-12.5* hct-35.9* mcv-89 mch-31.0 mchc-35.0 rdw-13.8 plt ct-133* 07:15am blood wbc-5.7 rbc-2.71* hgb-8.5* hct-24.1* mcv-89 mch-31.2

disease. he was admitted following cath for coronary bypass surgery. he usual pre-operative work-up prior to surgery. on he was brought to the operating room where he a coronary artery bypass graft x 2. please see operative report for surgical details. he tolerated the procedure well and was transferred to the csru for invasive monitoring in stable condition. later on op day sedation was weaned.
