1. A method of reducing left ventricular dilation, comprising:
- advancing at least a portion of a cardiac bridge into a posterior vein of a left ventricle, the cardiac bridge including a proximal anchor, a distal anchor and a bridge member connecting the proximal and distal anchors;
expanding the proximal and distal anchors; and
altering a curvature of the bridge member between the proximal and distal anchors such that the bridge member applies a compressive force to a wall of the left ventricle.

Abstract
A device and method for reducing ventricular dilation by placing one or more cardiac bridges into vessels extending along a length of the ventricle. Each cardiac bridge preferably includes a pair of anchors and a bridge member secured therebetween. The tension in the bridge member is increased to compress the ventricle and thereby reduce the dilation. In another embodiment, the bridge member is tensioned to reshape the left ventricle for reducing tension on the chordae tendinae in the heart to improve valve function.

6. A method of reducing ventricular dilation, comprising:
-
advancing at least a portion of a first cardiac bridge into a first vein that branches from a coronary sinus and extends along a length of a left ventricle, the first cardiac bridge including a first proximal anchor, a first distal anchor and a first bridge member; advancing at least a portion of a second cardiac bridge into a second vein that branches from the coronary sinus and extends along the length of the left ventricle, the second cardiac bridge including a second proximal anchor, a second distal anchor and a second bridge member; joining the first and second bridge members; and increasing tension in the first and second bridge members such that the bridge members applies a compressive force to the ventricular wall. - View Dependent Claims (7, 8, 9, 10, 11, 12)

13. A method for improving coaption of leaflets of a mitral valve, comprising:
-
advancing at least a portion of a cardiac bridge into a posterior vein of the left ventricle, the cardiac bridge including a proximal anchor, a distal anchor and a bridge member connecting the proximal and distal anchors; expanding the proximal and distal anchors; and applying tension to the bridge member for reducing a height of a left ventricle and thereby reducing tension on the chordae tendinae.
