Intraoperative Transesophageal Echocardiography Using a Quantitative Dynamic Loading Test for the Evaluation of Ischemic Mitral Regurgitation

A quantitative loading test with fluids and phenylephrine is useful to avoid underestimation of ischemic MR by intraoperative transesophageal echocardiography, and may detect significant MR in some patients who had unloaded LVs and nonsignificant MR during their preoperative assessment.
