“…[16], performed on a group of 38 patients with ages ranging from 1 year to 69 years, are close to those obtained in our study in terms of the parameter values obtained 24 h post-procedure. The cited authors reported a marked decrease of indexed RA surface area during this time; however, the indexed RA surface area did not normalize during the subsequent 2 years of follow-up, while in our study it normalized after 3 months of follow-up.…”

“…[16] reported normalization of indexed RV volume (RV volume/BSA) in children 2 years after ASD II closure with the ASO. It seems that due to the complexity of the RV geometry, in our opinion, the M-mode dimension alone does not capture the real ongoing changes in RV size after percutaneous closure of ASD and adding two-dimensional measurements could better reflect the ongoing changes.…”

IntroductionThe aim of this study was to evaluate the right atrial (RA) and right ventricular (RV) size, and the speed of their normalization, in children after percutaneous closure of secundum atrial septal defect with the Amplatzer septal occluder.Material and methodsThe study group consisted of 42 children, aged 4.5 to 18.5 years. The following measurements (indexed to body surface area) were performed using 2D echocardiography: longitudinal, transverse axis and area of RA, RV inflow dimensions at one-third, and halfway between the tricuspid annulus and the apex (in the apical 4-chamber view), short axis and M-mode RV diastolic dimensions. All measurements were obtained 24 h and 1, 3 and 12 months after the procedure, then annually over 4 years of follow-up, and compared with the values obtained from the control groups.ResultsA significant decrease in all RA and RV values was observed after 24 h. Right ventricular transverse dimension normalized after 1 month, the RA longitudinal axis and area and the RV inflow dimensions after 3 months, and the RA transverse axis and M-mode RV diastolic dimension after 2 years, but the ratio of transverse to longitudinal RA axis remained significantly higher.ConclusionsRight atrial and right ventricular measurements decrease rapidly during the first 24 h, and most of them normalize within a 3-month period. M-mode RV diastolic dimension does not capture the real RV changes. Amplatzer septal occluder closure of ASD influences the RA geometry, which is reflected by the higher transverse to longitudinal RA axis ratio.

Introduction: Mitral valve prolapse (MVP) is the most common anomaly of the mitral valve. Several studies have shown prevalence of MVP in atrial septal defect (ASD) especially secundum types (II). The aims of this study is to show the potential role of 3D echocardiography in improving the diagnosis of MVP and to depict the relationship between reverse remodeling of the right and left ventricles (RV, LV) and MVP after transcatheter closure of ASD II. Methods: Sixty patients underwent transcatheter closure of ASD II and completed follow up by 2D and 3D echocardiography in Cairo University Children Hospital before the procedure and at 24 hours, 1 and 6 months after the procedure. Results: 3D echocardiography was more accurate than 2D echocardiography in detecting MVP frequency in ASD II patients (75% vs. 50%). Maximum statistically significant remodeling was detected by 3D echocardiography 1 month after the procedure (RV: LV ratio by 3D echocardiography 1.9±0.03 24 hours after the procedure vs. 1.6±0.03 1 months after the procedure, P < 0.01) while 2D echocardiography was delayed in detecting biventricular reverse remodeling. 3D derived RV: LV ratio was accurate in detecting MVP status with a sensitivity of 88%.

“…Often there is a rapid decrease of atrial dimensions after ASD closure [6, 7], probably by leading to decrease in wall tension and reduction of the arrhythmic substrate. This is also exemplified by one of the patients in our series, who had been excluded because of persistent AF before ASD closure.…”

BackgroundTranscatheter closure of interatrial septal communications (IASC) is being increasingly performed, while less is known about predictors and incidence of new onset atrial fibrillation (AF) after device closure. Hitherto, most studies have only analyzed some parameters potentially influencing the occurrence of AF, variously omitting others and thus limiting interpretation of results.MethodsDescriptive, single author, observational study with 68 consecutive patients [aged 53.6 ± 15.1 years; 32 females (47%)] undergoing IASC closure, being followed up for 16.8 (±9.9; 6–42) months. Two patients with AF previous to device implantation had been excluded. Parameters analyzed included age and gender as well as presence of coronary artery disease, hypertension, atrial size, body mass index, device size, and presence of residual shunt. Device size was normalized to maximal disk diameter as declared by the manufacturer.ResultsThe incidence of new onset AF was 10.3% in the first 6 months after IASC closure. The only two predictors linked to AF were device size (P = 0.002) and, although not reaching significance level, right atrial dilatation (P = 0.08).ConclusionOccluder size was the only significant predictor of post-procedural AF, especially after PFO closure. Although there may be constraints (defect size, presence of an atrial septal aneurysm) that may dictate implantation of a larger device, it is reasonable to implant them “as large as necessary, as small as possible”. The influence of atrial dimensions on post-procedural onset of AF must be further investigated.
