Clinical TrialIntraoperative transesophageal echocardiography using a quantitative dynamic loading test for the evaluation of ischemic mitral regurgitation.
Intraoperative transesophageal echocardiography may underestimate ischemic mitral regurgitation (MR) as a result of the unloading effect of general anesthesia on the left ventricle (LV). An intraoperative loading test could prove useful to avoid underestimation of ischemic MR. ⋯ 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.
