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. Related Resources & Content
