This disclosure includes apparatuses and techniques to access the right ventricle via trans-femoral vein threading a catheter or catheters to the apex or bottom of the right ventricle. Piercing through the venous or right side of the heart in the interventricular septal wall to access the left ventricle a catheter can be passed to turn upward pointing to the mitral valve. From this access point in the left ventricle the flail mitral leaflet can be sutured and tethered pulling it back into position and reattached with a grounding anchor in the right ventricle or imbedding the anchor into the septal wall. The interventricular septal wall crossing technique could include the passing of a coaxial catheter through the first access catheter where the first access catheter could guide to direct the internal or second coaxial catheter toward the flail mitral leaflet.
