Figure 1:

Rendered illustration of the posterior ventricular anchoring neochordal (PVAN) repair and the hypothesized forces experienced on the repair suture throughout the cardiac cycle. During diastole (A), the PVAN suture is relaxed and experiences no tension. As systole begins (B), the closing posterior leaflet is held in position for optimal coaptation by the PVAN repair suture. Forces on the PVAN suture peak immediately before leaflet coaptation. Once the anterior and posterior leaflets coapt (C), the forces on the PVAN suture begin to fall as the leaflet forces are distributed throughout the 2 opposing leaflets (D).
