maze procedure, and left atrial appendage ligation history of present illness: 67 y/o female with known mvp/mr who has been followed by serial echo's and now has new onset atrial fibrillation. most recent echo showed 3+mr mitral chordae and cardiac cath showed 4+mr with normal coronaries. past medical history: hypertension, hyperlipidemia, mitral valve prolapse and regurgitation, breast cancer

varicosities neuro: a&o x 3, mae, non-focal pertinent results: echo: pre bypass: the left atrium is moderately dilated. the right atrium is moderately dilated. left ventricular wall thicknesses are normal. the left ventricular cavity is moderately dilated. 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. the aortic arch is mildly dilated. there are simple atheroma in the aortic arch. the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion and mild (1+) ai. the mitral valve leaflets are mildly thickened. there is partial mitral leaflet flail involving a2 and a1. there may be posterior prolapse as well. severe (4+) mitral regurgitation is seen. post bypass: there is a biprosthetic mitral valve which appears well seated without perivalvular leaks or regurgiqation. peak gradient 3 mm hg, mean gradient 1 mm hg. the left atrial appendage is now absent with a tiny stump evident. biventricular function remains normal. ai and tr are unchanged. aortic contours are intact. remaining exam is unchanged. all findings discussed with surgeons at the time of the exam. cxr: patient is status post sternotomy. there is volume loss in the right lower lobe. there is no focal infiltrate or effusion. sternal wires are present as are left axillary clips. there is a small left apical pneumothorax. 03:00pm blood wbc-3.8*

started on heparin before surgery on . on he was brought to the operating room where he underwent a mitral valve replacement and maze procedure with left atrial appendage ligation. following surgery he was transferred to the cvicu for invasive monitoring in stable condition. within 24 hours she was weaned from sedation and awoke neurologically intact. he was started on beta blockers and diuretics and diuresed towards he pre-op weight throughout her hospital course. on post-op day one he was transferred to the telemetry floor for further care. on post-op day two his chest tubes were removed. later on this day his heart rhythm converted from sinus rhythm to atrial fibrillation. he was immediately treated with amio and lopressor. the following day his epicardial pacing wires were removed and his beta blockers were increased and he was started on coumadin. on hospital day four he appeared to be doing well and was discharged home with vna services and the appropriate follow-up medications. his inr will be followed at the clinic with a goal inr of .5. medications on admission: aspirin 325mg qd, atenolol 25mg qd, atorvastatin 10mg qd, doxazosin 2mg , lisinopril 20mg qd, mvi,
