Abstract

Background: Balloon sizing (BS) has been used for device size selection in percutaneous atrial septal defect (ASD) closure. Due to its limitations, alternative imaging techniques like three-dimensional transesophageal echocardiography (3D-TEE) are valuable for guiding ASD device size selection during ASD closure procedures. The purpose of this study was to compare ASD sizing using measurements obtained from 3D–TEE to those utilizing the standard balloon sizing method. Methods: We identified 53 patients with single secundum type ASD without PFO who underwent percutaneous closure at the Tehran Heart Center between 2019 and 2022. Balloon sizing was performed in all patients with the stop-flow technique, and the choice of device size was determined based on the sizing derived from BS. 3D-TEE imaging was performed before the intervention, and the ASD shape and quality of ASD rims were assessed. Results: Among the 53 patients who underwent single ASD device closure, multiple 3D TEE measurements significantly correlated with balloon sizing results. This included defect area, perimeter, and diameter obtained from 3D-TEE images multi-planar reconstruction. ASD perimeter detected by 3D TEE had the best correlation with BS results. When divided by the shape of ASD, there was no significant difference between our 3D-images data and BS in round or oval-shaped ASDs. Conclusion: The 3D-TEE study is reliable for assessing ASD configurational characteristics in percutaneous device closure candidates. 3D-TEE has the potential to accurately determine the appropriate device size and reduce complications, costs, and procedural duration. Further research is needed to validate these findings and establish the role of 3D-TEE measurements in guiding the best treatment decisions for ASD closure. © 2024 Wiley Periodicals LLC.
