Clinical Scorecard: ASE Details M-TEER Imaging Guidance
At a Glance
| Category | Detail |
|---|
| Condition | Mitral Valve Transcatheter Edge-to-Edge Repair (M-TEER) |
| Key Mechanisms | Standardization of intraprocedural imaging and communication to improve procedural success and patient outcomes. |
| Target Population | Patients undergoing M-TEER procedures. |
| Care Setting | Interventional cardiology and echocardiography. |
Key Highlights
- Guidelines aim to standardize imaging protocols and communication among clinicians.
- Greater institutional experience correlates with improved procedural outcomes.
- Recommendations cover various imaging modalities including 2D, 3D, and MPR.
- Stepwise imaging protocol includes nine procedural stages.
- Eligibility for M-TEER is based on multiparametric assessment.
Guideline-Based Recommendations
Diagnosis
- Confirm severity and mechanism of mitral regurgitation (MR) during baseline evaluation.
- Assess ventricular function and identify contraindications.
Management
- Use 3D MPR for improved procedural guidance and communication.
- Standardize image orientation and nomenclature throughout the procedure.
Monitoring & Follow-up
- Assess residual MR and transmitral gradient before device deployment.
Risks
- An MVA below 3.5 cm² is often a contraindication to M-TEER.
Patient & Prescribing Data
Patients with mitral regurgitation suitable for transcatheter repair.
Minimum posterior leaflet length requirements vary by device type.
Clinical Best Practices
- Maintain appropriate height and alignment during transseptal puncture.
- Confirm adequate leaflet insertion and tissue capture before device deployment.
