Mission M-Possible: Mitral Transcatheter Edge-to-Edge Repair in Mitral Annular Calcification Using the Crab-Walk Technique.

ABSTRACT:

Background

Mitral annular calcification (MAC) complicates transcatheter interventions for degenerative mitral regurgitation (DMR), particularly with small mitral valve orifice areas (MVOAs).

Case summary

An 83-year-old woman with severe DMR, severe MAC, and MVOA of 3.8 cm² presented post-heart failure hospitalization with declining function. High surgical risk and unfavorable transcatheter mitral valve replacement anatomy (neo-LVOT 0.30 cm²) limited options to transcatheter edge-to-edge repair (TEER). Using the Edwards PASCAL precision system and the "Crab-Walk" technique (independent leaflet clasp manipulation for MAC-related challenges), TEER reduced mitral regurgitation to mild (1+), with a 2 mmHg gradient at 3 months. The patient was weaned off oxyg
