“…It is not surprising that many ASDs are not circular in shape, and indeed complex ASD shapes have been described by some authors16,19,20,21,22,23). Three-dimensional (3D) images should be reconstructed from 2D images for a complete understanding of defect shape.…”

“…By contrast, the excellence of 3D images has been reported by many interventionists. Reconstructed en-face CT or TEE images are superior for visualizing the morphology and the number of defects16,22,23,24,25). The morphology and location of the defect may be more easily understood on 3D images obtained from CT than those obtained from TEE.…”

Transcatheter closure of atrial septal defects has become a popular procedure. The availability of a preprocedural imaging study is crucial for a safe and successful closure. Both the anatomy and morphology of the defect should be precisely evaluated before the procedure. Three-dimensional (3D) echocardiography and cardiac computed tomography are helpful for understanding the morphology of a defect, which is important because different defect morphologies could variously impact the results. During the procedure, real-time 3D echocardiography can be used to guide an accurate closure. The safety and efficiency of transcatheter closures of atrial septal defects could be improved through the use of detailed imaging studies.

“…However, an accurate dimension related to the shape of the defect is considered important for the successful transcatheter closure because the ASO is uniform. There are studies that have described the complex shapes of ASD with a three-dimensional trans-esophageal echocardiogram 6,7,9,10. However, we did not perform a three-dimensional trans-esophageal echocardiogram for our patients' series.…”

PurposeFor the successful completion of transcatheter closure of atrial septal defects with the Amplatzer septal occluder, shape of the defects should be considered prior to selecting the device. The purpose of this study is to evaluate the results of a transcatheter closure of oval shaped atrial septal defect.Materials and MethodsFrom November 2009 until November 2011, cardiac computed tomography was performed on 69 patients who needed a transcatheter closure of atrial septal defect. We defined an oval shaped atrial septal defect as the ratio of the shortest diameter to the longest diameter ≤0.75 measured using computed tomography. A trans-thoracic echocardiogram was performed one day after and six months after.ResultsThe transcatheter closure of atrial septal defect was performed successfully in 24 patients in the ovoid group and 45 patients in the circular group. There were no serious complications in both groups and the complete closure rate at 6 months later was 92.3% in the ovoid group and 93.1% in the circular group (p>0.05). The differences between the device size to the longest diameter of the defect and the ratios of the device size to the longest diameter were significantly smaller in the ovoid group (1.8±2.8 vs. 3.7±2.6 and 1.1±0.1 vs. 1.2±0.2).ConclusionTranscatheter closure of an oval shaped atrial septal defect was found to be safe with the smaller Amplatzer septal occluder device when compared with circular atrial septal defects.

“…However, a 2D TEE cannot accurately define a noncircular-shaped ASD and can underestimate the area of a complex-shaped ASD, which may result in residual shunt or embolization [6]. There are several studies that have described the complex shapes of ASD with a 3D TEE [6,7,11,14]. However, TEE is inconvenient for patients and has the potential to damage the esophagus.…”

“…There have been various studies suggesting that real-time 3-dimensional (3D) TEE is very useful in evaluating the morphology of ASD and guiding device closure [6,7,8,9,10]. The use of en-face imaging has been evaluated for device closure of ASD and was found to be superior in visualizing the defect morphology [11,12,13]. We chose to extend this observation by investigating whether the defect area measured on en-face images might be more important for successful device closure than the diameter.…”

Objectives: It was our aim to evaluate whether the defect area plays a crucial role in successful device closure of atrial septal defects (ASDs). Methods: The long and short diameters of the defect were measured on en-face images. The defect area was then measured by planimetry. The device size compared to the defect length and defect area was analyzed in each group. Results: There were 22 patients in the circular group and 45 patients in the noncircular group. The defect area did not differ between the groups (201.6 ± 107.1 vs. 245.6 ± 127.6 mm²). Although the length between the device size and the long diameter differed between the groups (3.4 ± 2.0 vs. 0.8 ± 3.7 mm; p = 0.003), there was no difference in the ratio of the device area compared to the defect area, which was constant even in the noncircular defect (1.73 ± 0.41 vs. 1.72 ± 0.53 mm²; p = 0.947). The device size was positively correlated with the defect area (p < 0.01). Conclusion: The defect area measured by planimetry on en-face images might be useful in selecting the device size for transcatheter closure of ASDs.
