Abstract:
Transcatheter mitral valve implantation (TMVI) represents a promising approach to treating mitral valve regurgitation in patients at increased risk of perioperative mortality. Similar to transcatheter aortic valve replacement (TAVR), TMVI relies on pre- and periprocedural noninvasive imaging. Although these imaging modalities, namely echocardiography, computed tomography, and fluoroscopy, are well established in TAVR, TMVI has entirely different requirements. Approaches and nomenclature need to be standardized given the multiple disciplines involved. Herein we provide an overview of anatomical principles and definitions, a methodology for anatomical quantification, and perioperative guidance.
