We report the systematic use of 4-dimensional intracardiac echocardiography (4D-ICE) as an intraprocedural imaging modality in transcatheter annular repair therapies. Twenty-six patients enrolled in the U.S. Food and Drug Administration–approved early feasibility study were analyzed to compare 4D-ICE and TEE. Results showed that 4D-ICE was predominantly used in the lateral annulus (Figures 2 and 3) and improved visualization compared with TEE. [No abstract; excerpt from article].
