Cryoballoon pulmonary vein isolation and left atrial appendage occlusion prior to atrial septal defect closure: A case report

Figure 1 Reconstruction of pulmonary vein and left atrial appendage by cardiac computed tomography. A: Reconstruction of pulmonary vein; B-C: Reconstruction and measurement of left atrial appendage (LAA); D: LAA occluder was released. Orange arrow shows LAA occluder.

Figure 2 Cryoballoon ablation. A-D: Cryoballoon ablation of all four pulmonary veins with good balloon occlusion; E-F: Preoperative and postoperative electrocardiogram. White arrows show balloon occlusion.

Figure 3 Outcome and follow-up. A: Preoperative echocardiography for atrial septal defect (ASD); B: Final X-ray image after left atrial appendage occlusion and ASD occlusion; C: Postoperative echocardiography for ASD; D: Follow-up at 3 mo by transesophageal echocardiography. Orange arrow shows ASD occluder; white arrow shows left atrial appendage occluder.
