Abstract

As the number of mitral valve transcatheter edge-to-edge repair procedures increases, there are catheter operators and interventional echocardiography operators performing these procedures with variable expertise. Expert imaging is paramount for the success of these procedures and requires knowledge of mitral valve anatomy, the ability to quickly manipulate two-dimensional (2D) and three-dimensional (3D) images in real time, and sufficient procedural experience to anticipate challenges and offer imaging solutions. There are currently no standard algorithms for the interventional echocardiographer to direct a successful mitral valve transcatheter edge-to-edge repair procedure. This guideline sets forth imaging views and the standard procedural steps and defines the imaging content that must be communicated using 2D, biplane, 3D volume, and/or multiplanar reconstruction 3D formats.
