catheter-based mitral valve clip repair is an effective procedure in selected patients with mitral regurgitation. Fluoroscopy and 2-dimensional transesophageal echocardiography (2D TEE) are the primary imaging modalities for guidance mitral-clip procedure. Real-time 3-dimensional transesophageal echocardiography (RT 3D TEE) has been recently suggested as a “complementary” imaging modality. However, whether the use of this mitral-clip technique may offer real benefits over standard imaging techniques is not yet established. The following collage, taken from a series of 22 patients, shows side-by-side images obtained by fluoroscopy, 2D TEE, and RT 3D TEE. While essential data during the procedure are provided by the use of the 2 standard imaging techniques and the most crucial step of the procedure (i.e., the capture of mitral leaflets) is always guided by 2D TEE, our collage demonstrates that in almost every step of the mitral-clip procedure, RT 3D TEE may provide new additional useful data. The more precise anatomic information, the fine details of the devices and the precise relationship of catheters/clip with surrounding anatomic structures, may enhance the confidence of imaging interpretation and eventually improve the efficiency of the procedure.
