AbstractPatients with atrial septal defect have an increased risk for atrial fibrillation. Increased P-wave dispersion predicts the development of atrial fibrillation. The aim of this study was to determine difference in P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure in childhood. A total of 68 children (the mean age was 7.2 plus or minus 3.3 years; the mean secundum atrial septal defects diameter was 17.3 plus or minus 5.4 millimetres) were evaluated in this study. Transcatheter closure was attempted in 41 children with secundum atrial septal defects, and the defect in 27 patients was closed by surgical techniques. P maximum, P minimum and P dispersion were measured by the 12-lead surface electrocardiography. P maximum, P minimum and P dispersion were found to be similar in patients with pre- and post-procedure (98.0 plus or minus 19.3 versus 95.1 plus or minus 23.0 milliseconds; 68.0 plus or minus 20.8 versus 67.6 plus or minus 24.3 milliseconds, 29.9 plus or minus 11.0 versus 27.1 plus or minus 12.1 milliseconds, respectively). There was no statistical significance in the comparison of P dispersion between the two groups. But in the surgical group, P-wave dispersion was decreased more significantly compared with baseline values (p-value equal to 0.03). In conclusion, there is no P dispersion between transcatheter closure with Amplatzer septal occluder and surgical closure of secundum atrial septal defect.

<p><b>Background:</b> For successful transcatheter closure of an atrial septal defect with the Amplatzer septal occluder, the shape of the defect should be considered before selecting the device size. The purpose of this study was to evaluate the results of transcatheter closure of an ovoid atrial septal defect.</p><p><b>Methods:</b> Between January 2010 and February 2012, cardiac computer tomography examinations were performed in 78 patients who subsequently underwent transcatheter closure of an atrial septal defect. In this retrospective study, we reviewed these patients' medical records. We defined an ovoid atrial septal defect as a value of 0.75 for the ratio of the shortest diameter of the defect to the longest diameter, as measured in a computed tomography image. Transthoracic echocardiography examinations were made at 1 day and 6 months after the procedure.</p><p><b>Results:</b> Transcatheter closure of an atrial septal defect was successful in 26 patients in the ovoid-defect group and in 52 patients in the round-defect group. There were no serious complications in either group, and the rate of complete closure at 6 months was 92.3% in the ovoid-defect group and 93.1% in the round-defect group (<i>P ></i> .05). The mean (SD) difference between the device size and the defect's longest diameter, and the mean ratio of the device size to the longest diameter were significantly smaller in the ovoid-defect group (1.7 � 2.9 versus 3.8 � 2.5 and 1.1 � 0.1 versus 1.3 � 0.2, respectively).</p><p><b>Conclusions:</b> Transcatheter closure of an atrial septal defect is indicated even for an ovoid atrial septal defect. Ovoid atrial septal defects can be closed successfully with smaller sizes of the Amplatzer septal occluder than for round atrial septal defects.</p>

AbstractPurposeTo determine the frequency and factors associated with increase in microembolic signals during transcatheter closure of atrial septal defect using the Amplatzer septal occluder.MethodsDuring the procedure in 16 patients, we measured microembolic signals using transcranial Doppler. Procedure time was divided into five periods: right cardiac catheterisation; left cardiac catheterisation; left cardiac angiocardiography; sizing and long sheath placement; device placement and release. We compared numbers of microembolic signals among the five periods and identified factors associated with them.ResultsMean size of septal occluder was 16 millimetres in diameter. Total number of microembolic signals was a median of 31.5, ranging from 3 to 113. Microembolic signals in three periods, left cardiac catheterisation; sizing, and long sheath placement; and device placement and release, were not significantly different from one another, but were significantly higher than those in the remaining two periods, right cardiac catheterisation and left cardiac angiocardiography (median was 9 in left cardiac catheterisation; 6 in sizing and long sheath placement; 6.5 in device placement and release, versus 0 in right cardiac catheterisation and 1 in left cardiac angiocardiography, p less than 0.05, respectively). Importantly, the time for device manipulation positively correlated with total number of microembolic signals (r equals 0.77, p less than 0.001), although fluoroscopic time, age, or size of septal occluder did not.ConclusionsTranscatheter closure of atrial septal defect using the Amplatzer septal occluder produces microemboli, especially during device placement. To minimise the risk of systemic embolism, we must decrease the time for device manipulation.
