Why the study?
There is a push to adopt a minimalist approach using conscious sedation instead of general anesthesia for transcatheter mitral ViV, making intracardiac echocardiography feasible instead of transesophageal echocardiography.
Four-dimensional ICE can be used to guide transcatheter mitral valve-in-valve procedures under conscious sedation, supporting a minimalist approach.
Supports feasibility of 4D ICE-guided mitral ViV under sedation; hypothesis-generating and requires prospective validation.
Transcatheter mitral valve-in-valve (ViV) has emerged as a safe and effective therapeutic option for patients with a degenerated mitral bioprosthesis. As procedural techniques mature and operator experience improve, there is a push to adopt a "minimalist" approach of using conscious sedation instead of general anesthesia for faster recovery. The heavy reliance on fluoroscopy for ViV deployment makes feasible the use of intracardiac echocardiography (ICE) instead of transesophageal echocardiography for other procedural imaging requirements. We hereby use a case example to illustrate a step-by-step approach of using four-dimensional ICE to guide transcatheter mitral ViV under conscious sedation.
