A representative case using intracardiac echocardiography and CT reconstruction for atrial fibrillation catheter ablation in a patient with cor triatriatum. A, 3D reconstruction of the LA image by computed tomography (CT) is shown in LAO view and PA view. The location of the membrane is marked with dotted lines. B, LA geometry is created by real‐time intracardiac echocardiography under the guidance of reconstructed CT. The PVs are identified above the membrane by intracardiac echocardiography and the sound geometry is created. 3D, three‐dimensional; LA, left atrium; CT, computed tomography; LAO, left anterior oblique; PA, posterior anterior; PV, pulmonary vein
