Key result
Planned dual-access strategy may facilitate safe device delivery in complex mitral paravalvular leaks.
Why the study?
In patients with multiple, complex mitral paravalvular leaks, catheter alignment, stability, or prosthetic leaflet interaction can limit a single-access approach.
Does a dual-access strategy (DASH) facilitate safe device delivery in patients with complex mitral paravalvular leaks?
Does a dual-access strategy (DASH) facilitate safe device delivery in patients with complex mitral paravalvular leaks?
A dual-access strategy may be a viable technical option for closing complex mitral paravalvular leaks when single-access approaches are inadequate.
May complement single-access in complex mitral PVLs with alignment limits; leaves open indications, safety, and durability pending larger series.
In selected patients with multiple, anatomically complex mitral PVLs-particularly when catheter alignment, stability, or prosthetic leaflet interaction limits a single-access approach, a planned dual-access strategy may represent a complementary technical option to facilitate safe device delivery. Larger series and longer follow-up are needed to define the indications, safety profile, and durability of the DASH approach.

Coppi et al. (2026) studied Mitral Paravalvular Leaks. Dual Access Strategy for Hemodynamic Closure (DASH) was evaluated. A planned dual-access strategy (DASH) may represent a complementary technical option to facilitate safe device delivery for complex mitral paravalvular leaks.
