Effect of chronotropy and inotropy on stitch tension in the edge-to-edge mitral repair.
Circulation. 2007; (11 Suppl): I276-81
Our prior studies suggest that mitral annular septal-lateral (SL) diameter is the chief determinant of "Alfieri stitch" tension, but hemodynamic parameters may also play a role. We approximated the central edge of the mitral leaflets with a miniature force transducer to measure tension (T) at the leaflet approximation point during inotropic and chronotropic stimulation.
