doppler. there is mild symmetric left ventricular hypertrophy. the left ventricular cavity size is normal. 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 complex (>4mm) atheroma in the descending thoracic aorta. the aortic valve leaflets are severely thickened/deformed. there is critical aortic valve stenosis (valve area <0.8cm2). mild (1+) aortic regurgitation is seen. the mitral valve leaflets are moderately thickened. there is mild valvular mitral stenosis (area 1.5-2.0cm2). mild to moderate (+) mitral regurgitation is seen. post bypass patient is av paced and receiving an infusion of phenylephrine. biventricular systolic function is unchanged. bioprosthetic valve noted in the aortic position. the valve appears well seated. the leaflets are difficult to visualize. mild mitral regurgitation present. aorta is intact post decannulation cxr : impression: persistent patchy left lower lobe opacity, but probably somewhat improved, with a suspected tiny residual pleural effusion. : findings: in comparison with a preoperative study, there has been a cabg procedure performed. endotracheal tube tip lies approximately 7 cm above the carina and is at the mid clavicular level. right ij swan-ganz catheter is in the right pulmonary artery. nasogastric tube is coiled in the fundus of the stomach. left chest tube is in place and there is no pneumothorax. retrocardiac atelectasis is seen. impression: standard appearance following cabg. brief hospital course: the patient was admitted to the hospital and brought to the operating room on where the patient underwent coronary artery bypass grafting x3, left internal mammary artery graft to left anterior descending, reverse saphenous vein graft to the marginal branch and ramus intermedius and aortic valve replacement with 23-mm biocor epic tissue valve. overall the patient tolerated the procedure well and post-operatively was transferred to the cvicu in stable condition for recovery and invasive monitoring. pod 1 found the patient extubated, alert and oriented and breathing comfortably. the patient was neurologically intact and hemodynamically stable on no inotropic or vasopressor support. he did have some post operative confusion requiring haldol. at the time of discharge he was oriented x 3 and not requiring haldol. beta blocker was initiated and the patient was gently diuresed toward the preoperative weight. the patient was transferred to the telemetry floor for further recovery. chest tubes and pacing wires were discontinued without complication. he did have post operative atn with a peak crea to 3.0 and peak bun to 85. lasix was decreased and his renal function was stable at the time of discharge with bun 66, cre 2.0. he was hypertensive amlodipine was started the ace held secondary to his renal function. while working with pt his systolic blood pressure was 190. he was started on hydralazine with good effect. his foley catheter had to be reinserted on pod4 for urinary retention. he was restarted on his home dose of terazosin and foley was removed again on pod6 and he did void successfully. the patient was evaluated by the physical therapy service for assistance with strength and mobility. by the time of discharge on pod 12 the patient was ambulating independently the wound was healing and pain was controlled with tylenol. the patient was discharged to home with vna and pt. he will have his renal function checked on . he will follow-up with his nephrologist dr. in 2 weeks and dr. and his pcp in one month. medications on admission: amiodarone 200 qd hydrochlorthiazide 25 qs
