1. A method for treating a chamber of a heart comprising:

  • determining an effective diameter for a cross section of the chamber of the heart, the effective diameter corresponding to a pre-treated diameter of the chamber at the cross section;

    determining a desired diameter for the cross section of the chamber, the desired diameter being smaller than the effective diameter and the desired diameter corresponding to a desired volumetric shape of the chamber that is determined to provide an improved function of the chamber;

    calculating a change in diameter based on the effective diameter for the cross section and the desired diameter for the cross section;

    calculating a linear length of heart tissue to be excluded from the chamber at the cross section based on the calculated change in diameter;

    deploying a first anchor at a first anchor location within the chamber at the cross section;

    deploying a second anchor at a second anchor location within the chamber at the cross section, wherein a tension member couples the first anchor with the second anchor and wherein a length of the tension member approximates the calculated linear length of heart tissue to exclude from the chamber; and

    tensioning the tension member to reduce the length of the tension member between the first anchor and the second anchor and thereby bring opposing walls into apposition and reduce a volume of the chamber.
