ASE Issues First Standardized Imaging Guidelines for Mitral Valve Transcatheter Edge-to-Edge Repair

No prior standard existed for intraprocedural echo guidance during mitral transcatheter edge-to-edge repair. ASE now defines required 2D, biplane, and 3D imaging views and communication steps for each procedural stage.

• Guideline document from the American Society of Echocardiography; not an original research study with a primary statistical endpoint.
• Addresses variable operator expertise by standardizing imaging algorithms across all procedural steps, from transseptal puncture through clip deployment and result assessment.
• Limitation: recommendations are consensus/expert-opinion based; prospective outcome data validating adherence to these imaging protocols are not yet available.
