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.

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.

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.

Background: Although various synthetic materials and pericardium have been used for atrial septal defect (ASD) closure, investigators are continuing to search for an ideal material for this procedure. We report and evaluate a case in which autologous right atrial wall tissue was used for ASD closure. Case: In this case, we closed a secundum ASD of a 22-year-old woman who also had right atrial enlargement due to the defect. After establishing standard bicaval cannulation and total cardiopulmonary bypass, we opened the right atrium with an oblique incision in a superior position to a standard incision. After examining the secundum ASD, we created a flap on the inferior rim of the atrial wall. A stay suture was stitched between the tip of the flap and the superior rim of the defect, and suturing was continued in a clockwise direction thereafter. Considering the size and shape of the defect, we incised the inferior attachment of the flap, and suturing was completed. Remnants of the flap on the inferior rim were resected, and the right atrium was closed in a similar fashion. Results: During an echocardiographic examination, neither a residual shunt nor perigraft thrombosis was seen on the interatrial septum. The patient was discharged with complete recovery. Conclusion: Autologous right atrial patch is an ideal material for ASD closure, especially in patients having a large right atrium. A complete coaptation was achieved because of the muscular nature of the right atrial tissue and its thickness, which is a closer match to the atrial septum than other materials.

Abstract It is not uncommon to have prolapse of the atrial septal occluder device despite accurate measurement of atrial septal defect and an appropriately chosen device. This is particularly a problem in cases with large atrial septal defect with absent aortic rim. Various techniques have been described for successful implantation of atrial septal occluder in such a scenario. The essence of all these techniques is to prevent prolapse of the left atrial disc through the defect while the right atrial disc is being deployed. In this brief report, we illustrate the use of cobra head deformity of the device to successfully deploy the device across the atrial septum.

Echocardiographic Findings

Congenital heart defects have been occasionally reported in cattle and ventricular septal defect represents the most frequently encountered anomaly. The double-outlet right ventricle is a rare congenital ventriculoarterial malformation reported only in certain cattle breeds. We describe this rare and complex congenital cardiac malformation observed in a 10-day-old male Chianina calf. Clinical examination showed tachycardia, tachypnea, jugular pulses, cyanotic mucous membranes and a right apical systolic murmur. Transthoracic echocardiography revealed severe dilation of the right-sided cardiac chambers with a markedly hypoplastic left ventricle. Both aorta and pulmonary artery leaving the right ventricle in parallel alignment with the tricuspid valve were suggestive of a dual-outlet right ventricle. Interventricular and interatrial septal defects were also visualized. Post-mortem examination confirmed the echocardiographic findings. To the authors’ knowledge, a similar complex congenital cardiac malformation has not been reported in calves of the Chianina breed to date.
