Task: Answer Verification
Input (English): Question: Is transesophageal Echocardiographic Measurement of Cardiac Index by the Prosthetic Mitral Valve Method Similar to the Continuous Thermodilution Method Via a Pulmonary Artery Catheter?
Answer: A relatively weak correlation and lack of agreement between values of CI(PAC) and CI(MV) were observed in patients undergoing double-valve replacement. Therefore, transesophageal echocardiography might not be interchangeable with PAC-TD for measuring cardiac output or cardiac index. A regression equation is needed to correct the probable value of CI(PAC). CI(MV) might be useful as a quantitative or semi-quantitative cardiac output measurement.
Output (English): no
