Background Use of the Amplatzer septal occluder (ASO) for the closure of secundum atrial septal defect (ASD) has recently become the procedure of choice, while earlier the only treatment for ASD was surgical closure. This study compares the right ventricular indices of the ASO group with the surgical closure group one year after intervention in adults. Methods From January 2008 to February 2010, 38 patients with isolated atrial septal defect of the secundum type one year after surgical (n = 20, age = 27 ± 4 years, 13 females, 7 males) or Amplatzer septal occluder closure (n = 18, age = 25 ± 4 years, 12 females, 6 males) were studied. At the same time, thirty-one age-matched normal subjects (age = 26 ± 6 years, 23 females, 9 males) were included as the control group. Strain and strain rate of the right ventricle were measured. Results The mean values of strain of the midportion were −26% ± 11.7%, −8.9% ± 4.2%, and 24.5% ± 7.4% ( P < 0.001). Strain rates of the midportion were −2.19 ± 0.6 s−1, −1.2 ± 0.4 s−1, −1.9 ± 0.6 s−1 ( P < 0.001) in ASO, surgery, and control groups, respectively. Conclusion This study showed that the right ventricle might show better performance in the ASO than the surgery group in adults with ASD in midterm follow-up.

The article gives a comparative assessment of the results of surgery for atrial septal defect (ASD) surgery in patients living in low and high altitude conditions. sizes of the right ventricle were practically equal, but at the same time higher than the norm. Objective. To conduct a comparative analysis of the direct results of ASD plastic in patients living in low, medium and high mountains Material and methods. The study material included 30 patients with ASD living in highlands; the control group consisted of 30 patients living in flat areas. Using clinical methods and instrumental studies, an analysis of operated patients, ASD plastic in adult patients with complicated pulmonary hypertension, heart failure, cardiac arrhythmias and functional tricuspid insufficiency was performed. Results. The authors studied pulmonary arterial pressure (PAP) indices between the groups both in the preoperative and postoperative periods, the analysis showed significant differences. The parameters of the right ventricle (RV) in the preoperative period had significant differences, however, in the postoperative period, the sizes of the right ventricle were practically equal, but at the same time higher than the norm. Conclusion. Our observation data show a significant decrease in PAP in patients living in high altitude conditions. However, the decrease in the PAP indicators remained slightly higher than the standard indicators.

The functional change of the right ventricle (RV) after atrial septal defect (ASD) via transcatheter closure is well known. We assessed the immediate RV functional change using velocity vector imaging (VVI) with intracardiac echocardiography (ICE). Seventy-four patients who underwent transcatheter closure of an ASD were enrolled. VVI in the “home view” of ICE showing the RV was obtained before and after the procedure. Velocity, strain, strain rate (SR), and longitudinal displacement were analyzed from VVI data, and the changes of these parameters before and after the procedure were compared. The velocity of the RV decreased after ASD transcatheter closure (3.97 ± 1.48 to 3.56 ± 1.4, p = 0.024), especially in the RV inlet and outlet. The average strain decreased (−19.21 ± 5.79 to −16.87 ± 5.03, p = 0.002), as did the average SR (−2.28 ± 0.64 to −2.03 ± 0.61, p = 0.006). The average longitudinal displacement did not differ. With the VVI technique, we could clearly observe RV functional change immediately after transcatheter closure of the ASD. RV functional change with regional difference may reflect the heterogeneity of volume reduction and suggest subclinical RV dysfunction. These findings can enhance our understanding of the physiologic changes in the RV during reverse remodeling.

Atrial arrhythmias are associated with enlarged atrial chambers and an increased duration of the P wave. Repair of atrial defects within the oval fossa is expected to normalize atrial size. Few studies, however, have evaluated electrical and morphological atrial features after repair. Our study was performed to determine if atrial abnormalities exist after surgical closure of such atrial septal defects, and whether early closure improves outcome. We recruited patients who had undergone surgical closure of a defect within the oval fossa, so-called “secundum” atrial septal defects. Electrocardiograms, signal averaged electrocardiograms, and echocardiograms were performed. Two-tailed test and Pearson correlation was utilized for statistical analysis. The population consisted of 20 patients and 27 controls, with the mean age of the patient being 11.25 ± 5.10 years, their age at surgery 6.55 ± 5.10 years, and the time since surgery 4.70 ± 2.61 years. The size of the right (23.88 ± 6.35 ml/m2 versus 18.84 ± 4.43 ml/m2) and left (21.91 ± 12.47 ml/m2 versus 17.72 ± 4.83 ml/m2) atrium were significantly larger in the patients. The duration of the P wave (108 ± 16 ms versus 96 ± 8 ms) and the duration of the PR interval (155 ± 18 ms versus 138 ± 23 ms) were longer. No correlation existed between age or interval since surgery with atrial sizes or measurements of the signal averaged electrocardiogram. We conclude that, despite surgical repair, abnormalities exist in patients with an atrial septal defect. Early surgery does not appear to prevent the atrial abnormalities.

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.

Objective. To assess the effectiveness of a novel ultrasound wire for echo-guiding percutaneous atrial septal defect (ASD) closure in a sheep model. Methods. After right lateral thoracotomy, ASDs were created in 20 sheep by transseptal needle puncture followed by balloon dilatation. Animals were evenly randomized into 2 groups to undergo ASD closure using echography as the only imaging tool with either COOK wire (control group) or new ultrasound wire (study group). The total procedural time, passing time (time needed for the guide wire to enter the left atrium), frequency of delivery sheath dropping into the right atrium, frequency of arrhythmias, and 1-week rate of complications were compared between the two groups. Results. All animals survived defect creation procedures uneventfully. ASD devices were successfully implanted in all sheep. Compared with the control group, the study group had significantly (P<0.05) lower mean procedure time (15.36 ± 4.86 versus 25.82 ± 7.85 min), lower mean passing time (2.69 ± 0.82 versus 5.58 ± 3.34 min), lower frequency of the guide wire dropping into the right atrium (0% versus 40%), and lower frequency of atrial (4.41 ± 2.61 versus 9.60 ± 3.68) or ventricular premature contractions (0.75 ± 0.36 versus 1.34 ± 0.68), respectively, without serious complications up to one week. Conclusion. The novel ultrasound specialized guide wire was effective in echo-guiding percutaneous ASD closure.
