Summary of echocardiography and hemodynamic data. A TEE 2D image of midesophageal long axis view (MELAX) during baseline period depicting anatomic structures of interest: the left ventricle (LV), the left ventricular outflow tract (LVOT) and the aortic valve (AV). B MELAX view depicting Color Doppler (CD) through the LVOT. Red color in the Doppler scale corresponds to direction of blood flow from the LV, through the LVOT, and into the ascending aorta. C Shows MELAX image of mid-compression cycle when CCs were being directed to the LV (CC-LV). Anteroseptal wall of the LV is being compressed against the inferolateral wall of the LV and the AV is beginning to open. D and E M-mode image through the LVOT during CC-LV (D) and CC-LVOT (E) with unidimensional measurements of the diameter of this structure during the compression (yellow lines) and decompression (blue lines) phases of CPR. Overlapping hemodynamic measurements corresponding to simultaneous 10 s epochs comparing the two CC locations are shown in F (aortic pressures) and G (ETCO2)
