COMPARING TEE WITH ANGIOGRAPHIC SIZING OF WATCHMAN DEVICE FOR LEFT ATRIAL APPENDAGE CLOSURE

Overall agreement between TEE and angiographic measurement of LAA maximal width was 18% (kappa 0.13, p<0.01), moderate correlation (r=0.50; p<0.01); and agreement for LAA length was 7% (k= 0.03, p0.15) with modest correlation (r=0.33, p=0.01; figure) Agreement between hypothetical WATCHMAN siz...

Summary:Overall agreement between TEE and angiographic measurement of LAA maximal width was 18% (kappa 0.13, p<0.01), moderate correlation (r=0.50; p<0.01); and agreement for LAA length was 7% (k= 0.03, p0.15) with modest correlation (r=0.33, p=0.01; figure) Agreement between hypothetical WATCHMAN size vs actual WATCHMAN size implanted based on TEE was 19.6% (kappa 0.02, p=0.3); by angiogram was 17.7% (kappa 0.006, p=0.4), and integrated TEE + angiogram was 67.4% (kappa 0.6, p<0.001, Figure 1).
