  "abstract": "Historically, the complexity of patients being evaluated for mitral transcatheter edge-to-edge therapy (M-TEER) has been divided into 3 main categories: green zone: defined as cases where M-TEER is straightforward and not complex, yellow zone: cases with medium complexity where M-TEER is feasible but not entirely straightforward, and red zone: cases where you would not consider M-TEER as the first option and may be swayed toward consideration of other options like transcatheter mitral valve (MV) replacement or surgical management. However, the advancement in preprocedural planning with precise anatomical definition by 3-dimensional imaging modalities has changed how we address complex mitral regurgitation cases. The expansion of available devices for management of MV disease has changed the way we think about undertaking challenging M-TEER procedures. Management in the current era emphasizes meticulous preprocedural assessment of mitral regurgitation pathology, strategic planning for device implantation, judicious device choice, and early consideration of transcatheter MV replacement or other innovative transcatheter devices. This review article provides a comprehensive overview of the available data on M-TEER and outlines treatment strategies for complex cases within the context of contemporary transcatheter technologies.",
