However, the structure of the LAA is highly variable among individuals, and the optimal method for obtaining measurements remains unknown.<\/jats:p><\/jats:sec><jats:sec><jats:title>Hypothesis<\/jats:title><jats:p>We aimed to study the accuracy of left atrial computed tomography angiography (CTA), three\u2010dimensional (3D) reconstruction using CTA, two\u2010dimensional transesophageal echocardiography (2D\u2010TEE), and digital subtraction angiography (DSA) for measuring the diameter of the LAA and compare their value for selecting occluder size.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively evaluated data for 148 patients with nonvalvular atrial fibrillation who underwent successful LAAC. CTA and 2D\u2010TEE of the left atrium and pulmonary vein were performed before LAAC. We performed 3D reconstruction of the left atrium and LAA using Mimics and 3\u2010matics software. DSA of the LAA was performed during surgery.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Values measured via CTA 3D reconstruction were significantly higher than those measured using other methods. DSA\u2010measured values were significantly lower than those measured via CTA and CTA 3D reconstruction. Occluder size was positively correlated with LAA orifice diameter. The differences between occluder size and DSA, 2D\u2010TEE, CTA, CTA 3D reconstruction measurements were 4.96\u2009\u00b1\u20092.58, 4.64\u2009\u00b1\u20092.50, 4.04\u2009\u00b1\u20091.37, and 2.92\u2009\u00b1\u20091.38\u2009mm, respectively.
