Claim:
1. A method, comprising the steps of: defining, by a computer processor, a parametric model representing a shape of a portion of a heart; constructing, by the computer processor, a statistical prior of the shape from a dataset of other instances of the portion, the dataset including the portions of hearts from a plurality of patients, and wherein constructing the statistical prior comprises preparing segmented data meshes; fitting, by the computer processor, the parametric model to the statistical prior, wherein fitting the parametric model comprises computing anatomic features from the data meshes and computing correlation coefficients among different ones of the anatomic features; inserting a probe into a living subject, the probe having a mapping electrode; urging the mapping electrode into contacting relationships with tissue in a plurality of locations in the portion of the heart of the subject; acquiring electrical data from the respective locations; relating the electrical data to the fitted parametric model to produce an isosurface of the portion of the heart of the subject; and reconstructing the shape of the portion of the heart of the subject responsively to relating the electrical data.
