calcium-8.6 phos-5.2* mg-2.2 07:05am blood calcium-8.1* phos-2.2* mg-2.0 - xrays of her right knee show good hardware alignment without evidence of fracture or other complications. - tte (echo) the left atrium is mildly dilated. no atrial septal defect is seen by 2d or color doppler. left ventricular wall thicknesses and cavity size are normal. regional left ventricular wall motion is normal. left ventricular systolic function is hyperdynamic (ef>75%). there is no ventricular septal defect. right ventricular chamber size and free wall motion are normal. the diameters of aorta at the sinus, ascending and arch levels are normal. the aortic valve leaflets (3) appear structurally normal with good leaflet excursion. there is no valvular aortic stenosis. the increased transaortic velocity is likely related to high cardiac output. no aortic regurgitation is seen. the mitral valve appears structurally normal with trivial mitral regurgitation. the pulmonary artery systolic pressure could not be determined. there is no pericardial effusion. brief hospital course: the patient was admitted on and, later that day, was taken to the operating room by dr. for r tka without complication. please
