A difference of one or more device size intervals between the predicted size and the size actually implanted was defined as mismatching. Seventy\u2010eight patients were followed up by TEE to obtain occluder compression ratio. The correlation between LZD and the final implanted occluder size was 0.559, 0.641, 0.754, 0.760, 0.782, and 0.848 for LZD\u20102Dmax, LZD\u20102Dmean, LZD\u20103Dmax, LZD\u20103Dmean, LZD\u2010PDD and LZD\u2010DSAmax, respectively (<jats:italic>P<\/jats:italic>\u00a0&lt;\u00a0.001). Matching ratio between the size predicted by retrospective measurements of LZD and the device size actually implanted was 65%, 57%, 66%, 63%, 70%, and 83% for LZD\u20102Dmax, LZD\u20102Dmean, LZD\u20103Dmax, LZD\u20103Dmean, LZD\u2010PDD and LZD\u2010DSAmax, respectively.
