Why the study?
Intracardiac echocardiography has emerged as a promising modality for intraprocedural guidance of structural procedures, with newer catheters capable of acquiring real-time 4D volumetric images.
This case report illustrates the feasibility of using a novel 4D intracardiac echocardiography catheter for intraprocedural guidance during transcatheter valve-in-valve mitral valve replacement.
Supports feasibility of 4D ICE guidance in valve-in-valve TMVR; hypothesis-generating pending comparative trials.
The use of intracardiac echocardiography (ICE) has emerged as a promising imaging modality for intraprocedural guidance of various structural procedures, primarily related to its ease of use, moderate sedation, and in some cases, better image quality.1,2 The newer ICE catheters are equipped with the capability of acquiring three-dimensional volumetric images and real-time cine videos (four-dimensional [4D]).1,2 We hereby report a case of valve-in-valve transcatheter mitral valve replacement (TMVR) using the novel NuVision (NuVera Medical, Los Gatos, California) ICE catheter.
