A method of reducing ventricular dilation comprises 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 compresses the ventricle and thereby reduces the dilation along the ventricle wall. In another embodiment, the bridge member is tensioned to reshape the left ventricle for reducing tension on the chordae tendinae in the heart for improving valve function.
