Abstract
To study the reproducibility of and agreement between perioperative transesophageal echocardiographic (TEE) and radionuclide (RN) assessment of ventricular volumes and ejection fraction (EF).
A prospective, blinded comparison of two methods of measurement.
A surgical intensive care unit in a university hospital.
Patients after coronary artery bypass surgery.
Left ventricular volumes and ejection fraction were simultaneously measured by radionuclide ventriculography and transesophageal echocardiography. Two sets of measurements were made in rapid succession with a third set after an interval.
Reproducibilities of EF and ventricular volumes by TEE and RN were similar. At each set of measurements, the bias for radionuclide EF and TEE Simpson's rule EF, 0.03 ± 0.05, 0 ± 0.06, −0.01 ± 0.07, respectively, for radionuclide EF and TEE area length EF 0.01 ± 0.05, −0.01 ± 0.05, −0.03 ± 0.08, respectively, were significantly less than for radionuclide EF and TEE FAC 0.07 ± 0.05, 0.05 ± 0.05, 0.03 ± 0.09. Poor agreement was observed between RNTD-EDV, and both of the TEE EDV measurements.
EF measured by TEE area length and Simpson's rule method are as reproducible as TEE FAC and are more accurate estimates of RN EF. Poor agreement between methods of measuring end-diastolic volume was observed.
