5 Key Takeaways

• 1

  The ASE published guidelines to standardize intraprocedural imaging for mitral valve transcatheter edge-to-edge repair (M-TEER).

• 2

  The guidelines address variability in imaging protocols and emphasize the importance of transesophageal echocardiographic (TEE) guidance for procedural success.

• 3

  A stepwise imaging protocol is outlined, covering nine stages from baseline evaluation to final deployment and assessment of iatrogenic atrial septal defects.

• 4

  The guideline specifies desirable anatomic and hemodynamic thresholds for M-TEER eligibility, including mitral valve area and posterior leaflet length.

• 5

  Standardized communication and imaging orientation are recommended to enhance procedural consistency and improve collaboration between echocardiographers and operators.
