Figure 7 Early 2-Dimensional Appearances and Doppler Gradients After PHV Implantation

A PHV implantation has the potential to give excellent early morphologic and hemodynamic results. Transesophageal echocardiography long-axis views are shown before (A) and after (B) implantation of a PHV. Successful PHV implantation also leads to a marked early reduction in transaortic pressure gradient. Transaortic Doppler gradients in the same patient are shown before (C) and after (D) PHV implantation. Abbreviations as in Figure 1.
