spontaneous echo contrast is seen in the body of the left atrium. no spontaneous echo contrast or thrombus is seen in the body of the left atrium or left atrial appendage. no left atrial mass/thrombus seen (best excluded by transesophageal echocardiography). the right atrium is moderately dilated. no atrial septal defect is seen by 2d or color doppler. the estimated right atrial pressure is 0-5 mmhg. the left ventricular cavity is moderately dilated. overall left ventricular systolic function is mildly depressed (lvef= 40-50%). right ventricular chamber size and free wall motion are normal. the aortic root is moderately dilated at the sinus level. the sinuses of valsalva are dilated. the ascending aorta is markedly dilated the descending thoracic aorta is mildly dilated. there are simple atheroma in the descending thoracic aorta. there are three aortic valve leaflets. the aortic valve leaflets are mildly thickened. the aortic valve is abnormal. moderate to severe (3+) aortic regurgitation is seen. the mitral valve leaflets are myxomatous. there is moderate/severe mitral valve . there is partial mitral leaflet flail. there is moderate thickening of the mitral valve chordae. moderate to severe (3+) mitral regurgitation is seen. there is no pericardial effusion. post cpb: 1. prosthetic valve in the aortic and mitral position. well seated and stable, good leaflet

radiology final report chest (portable ap) 1:08 pm chest (portable ap) reason: r/o ptx medical condition: 79 year old man s/p avr and ct removal reason for this examination: r/o ptx procedure: chest portable ap on . comparison: , chest radiograph. history: 79-year-old man status post avr and chest catheter removal, rule out pneumothorax. findings: there is no pneumothorax. the chest drainage catheter has been removed. in addition, the endotracheal tube has been removed. a sheath for a swan-ganz catheter persists after the removal of the swan-ganz. note, however, that there is increase in the size of the cardiac shadow with a prominent left atrium visualized. small bibasilar atelectasis is noted. impression: 1. status post removal of a chest drainage catheter with no complication like pneumothorax. 2. the endotracheal tube and swan-ganz catheter have been removed. a sheath for a swan-ganz catheter persists terminating in the right brachiocephalic vein. 3. cardiac decompensation or pericardial effusion may explain the increase in the size of the cardiac shadow. prominent left atrium. ab the study and the report were reviewed by the staff radiologist. dr. dr. dr. approved: mon 6:32 am radiology final report ct head w/o contrast 9:11 am ct head w/o contrast reason: assess for infarct medical condition: 79 year old man s/p avr, post-op weakness l upper ext reason for this examination: assess for infarct contraindications for iv contrast: none. indication: postop weakness in the left upper extremity. evaluate for infarct. comparison: none. technique: non-contrast axial images of the head are obtained with 5-mm section thickness. ct head without contrast: there is no intracranial hemorrhage or shift of normally midline structures. right frontal subcortical rounded hyperdensity measuring approximately 15 x 10 mm and extending inferiorly into the centrum semiovale that may represent a subacute infarct though this is unclear. a posterior right parietal hypodense focus also could be due to acute/subacute infarct. more inferiorly a less hypodense focus (2:16) may represent a more recent, subacute, infarct. surrounding osseous structures are unremarkable. sphenoid sinus opacification is noted. cerumen is noted within the external auditory canals bilaterally. impression: hypodense areas in right cerebral hemisphere indicate infarcts of undetermined age but could be subacute. mri can help for further assessment. no hemorrhage. the study and the report were reviewed by the staff radiologist. dr. dr. approved: sat 1:01 pm brief hospital course:
