Intraoperative transesophageal echocardiogram images with color flow doppler of the main pulmonary artery (MPA), left pulmonary artery (LPA) and right pulmonary artery (RPA) prior to surgical pulmonary embolectomy. The images reveal significant flow acceleration across a dilated MPA (Panel A) and minimal to no antegrade flow into the LPA (panel B) and RPA (panel C). (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)

Fig. 1 shows TEE images of the MPA, LPA, and RPA prior to embolectomy, which shows flow acceleration across a dilated MPA and minimal to no antegrade blood flow into the LPA and RPA.
Intraoperative transesophageal echocardiogram images with color flow doppler showing the main pulmonary artery (MPA), left pulmonary artery (LPA) and right pulmonary artery (RPA) after surgical pulmonary embolectomy. The images reveal reduced flow acceleration across the MPA (Panel A) and significantly improved flow in the LPA (Panel B) and RPA (Panel C). (For interpretation of the references to color in this figure legend, the reader is referred to the Web version of this article.)

Fig. 2 demonstrates a reduction in flow acceleration across a markedly less dilated MPA and a significantly increased antegrade blood flow across the LPA and RPA.
