BACKGROUND Transcatheter closure of moderate sized atrial septal defects (ASD) has been demonstrated to be safe and effective. However, the feasibility of transcatheter closure of very large defects is less clear, particularly when an aortic rim of septal tissue is absent. METHODS The study included patients referred for transcatheter ASD closure with maximal ASD diameter ≥ 20 mm at pre-procedural transoesophageal echocardiography. Patients were grouped according to presence of moderately large (20-29 mm), very large (30-39 mm), or extremely large (≥ 40 mm) ASD size. Procedural success was defined by successful device deployment and absence of complications. RESULTS Forty-two patients (median age 40 years, range 12-85 years, 76% female) were included in the study. The mean maximal ASD diameter was 29.0 ± 7.4mm. Twenty-three patients had moderately large ASDs (23.0 ± 2.8mm); 13 had very large ASDs (33.1 ± 2.9 mm) and six had extremely large ASDs (41.3 ± 1.6 mm). The aortic rim was ab...

Background: Transcatheter closure of atrial septal defects (ASD) has been accepted world-wide as an alternative to surgical closure with excellent results. This interventional, non-surgical technique plays an important role in the treatment of ASD mostly in the developing world where resources are limited. Objectives: To report the outcomes and short term follow-up of transcatheter closure of ASD over a 12-year period at our institution with limited resources. Patients and Methods: This retrospective study included all patients with the diagnosis of secundum ASD and significant shunting (Qp/Qs > 1.5:1) as well as dilated right atrium and right ventricle who had transcatheter closure at Integrated Cardiovascular Center (PJT), Dr. Cipto Mangunkusumo Hospital between October 2002 and October 2014. One hundred fifty-two patients enrolled in this study were candidates for device closure. Right and left heart cardiac catheterization was performed before the procedure. All patients unde...
Transcatheter Device Closure of Secundum Atrial Septal Defect in Adult Patient
Acta Informatica Medica, 2021
Background: Atrial septal abnormalities are common congenital lesions remaining asymptomatic until adulthood in a great number of patients. The most frequent atrial septal defects in adults are ostium secundum atrial septal defect (ASD). Complications from untreated, hemodynamically significant ASD are atrial arrhythmia, paradoxical embolization, Eisenmenger's syndrome, pulmonary hypertension, and right ventricular failure. Objective: We present a case report of secundum ASD in adult female patient who underwent transcatheter device closure with Amplatzer occluder. Methods and Results: The case of female Bosnian patient 50 years old who lives in Belgium for 20 years ago and during her visit to Bosnia she came to our polyclinic for cardiological exam. Echocardiographic exam showed enlargement of left atrium (LAD 51mm), right atrium and ventricle (RAD 46mm, RVd 33mm), atrial septal defect 9mm with left right shunt Qp:Qs 2,3:1. Several months later transcatheter device closure with Amplatzer occluder was performed and subsequent symptomatic improvement reported after closure. Conclusion: Echocardiography has superior role for precise evaluation of ASD type secundum who are suitable for transcatheter device closure as primary treatment option. Transcatheter techniques has now become preferable to surgical repair and provide valid option of treatment for this type of CHD.

Registry to report our single-centre experience in closing defects of the atrial septum. Between 1996 and 2001, transcatheter device closure of significant atrial septal defects was performed in 32 adults (mean age 45.1 years, range from 15 to 76 years), using different device types. Six patients had a patent foramen ovale (PFO) and 26 patients had a secundum atrial septal defect (ASD II). Defects were selected by means of two-dimensional transoesophageal echocardiography (2D TOE). For 12 defects additional three-dimensional transoesophageal echocardiography (3D TOE) was performed. Mean balloon-stretched diameter was 19.3 mm (range from 11 to 24 mm). A device was successfully placed in all PFO patients (100%) without complications at follow-up. Successful immediate device placement occurred in 24 out of 26 ASD patients. Two immediate placement failures, 1 device embolisation and 1 device non-fixation, occurred and required urgent surgery. There was 1 patient with pericardial effusio...

. The aim of our study is to describe the 3-year results of transcatheter ASDs closure using the Amplatzer septal occluder (ASO) and ICE as the sole imaging tool both to select the device size and to monitor the procedure. Under local anesthesia, 135 consecutive eligible patients with ASDs (male/female = 45/90; mean age 42.2 ± 19.2 years; BSA 1.71 ± 0.7 m 2 ; mean pulmonary arterial pressure 30.4 ± 11.5 mmHg; mean Qp/Qs ratio 2.1 ± 0.6) underwent transcatheter closure using ASO and ICE. A 9F-9MHz mechanical transducer was used. Two orthogonal views on the transverse aortic valve and on the longitudinal four-chamber planes were obtained for quantitative ICE measurements, from which the diameters of the implanting ASO waist were to be derived. In all cases, we obtained a proper evaluation of ICE ASDs dimensions, leading to an optimal device size selection (mean size 25.0 ± 6.7 mm). Moreover, the ICE allowed us to monitor device deployment and to verify the effectiveness of the ASDs stented by ASO. There were no complications related to the procedure or to the use of ICE. During a mean follow-up period of 21.5 ± 12 months, the cumulative complete occlusion rates were 97.7, 97.0, 97.1, and 98% at 24 hours, 3 month, and 1 and 3 years, respectively. ICE is an effective and safe alternative to TEE and balloon-sizing maneuver during ASDs transcatheter closure procedures, allowing us to avoid the need of general anesthesia and leading to a similarly high percentage of occlusion rates with respect to the conventional method.

Abtract-The purpose of this study was to evaluate the safety and efficacy of transcatheter atrial septal defect (ASD) closure guided by transthoracic echocardiography (TTE). A total of 191 patients with ASD were recruited from two Chinese medical centers and TTE was carefully performed in multiple views to observe ASD number, position, diameter and relation with adjacent cardiac structures. All patients were divided into three groups based on their largest ASD diameters: 66 subjects with ASD diameter 5ϳ14 mm (group A); 60 subjects with ASD diameter 15ϳ20 mm (group B); and 65 subjects with ASD diameter 21ϳ38 mm (group C). Atrial septal occluders (ASOs) were successfully deployed in 188 patients (98.4%) and ASD was successfully closed at 6-mo follow-up in 185 patients (96.9%). The difference between diameters of ASO and ASD (ASO-ASD) in groups A, B and C were 3.9 ؎ 2.4 (0ϳ7) mm, 5.0 ؎ 2.6 (3ϳ8) mm and 6.2 ؎ 3.8 (5ϳ11) mm, respectively. In group A, no complications occurred. In group B, only four patients had mild complications such as sinus bradycardia, transient hematuria and migraine, all of which disappeared after treatment. In group C, one patient developed ASO migration into the right atrium and two patients had their ASO migrated into the right ventricular outflow tract. Immediately after the closure, 60 (90.9%), 53 (88.3%) and 53 (82.8%) patients had complete ASD closure; 2, 4 and 6 patients had trivial residual shunts; 4, 3 and 2 patients had small residual shunts; and 0, 0 and 2 patients had moderate residual shunts in groups A, B and C, respectively. Most of the residual shunts were persistent at 6-mo follow-up. No embolism or death at procedure and 6-mo follow-up occurred. In conclusion, TTE is a reliable technique for measurement of ASD diameter, guidance of transcatheter ASD closure and evaluation of residual shunts. Transcatheter ASD closure guided by TTE is safe and effective, especially in patients with ASD <20 mm. (E-mail: zhangyun@sdu.edu.cn) Crown

Intracardiac Echocardiography Evaluation in Secundum Atrial Septal Defect Transcatheter Closure
CardioVascular and Interventional Radiology, 2003
Purpose: This study was designed to assess the balloon sizing maneuvers and deployment of an Amplatzer Septal Occluder (ASO). In addition, intraprocedural balloon sizing was compared with off-line intracardiac echocardiographic measurements. Methods: The intracardiac echocardiography (ICE) measurements were: maximum transverse and longitudinal atrial septal defect (ASD) diameters in the aortic valve and fourchamber planes; area of the ASD and its equivalent circle diameter. Thirteen consecutive patients underwent transcatheter implantation of an ASO device using ICE guidance under local anesthesia. The device matching the balloon sizing diameter of the defect was implanted. Qualitative ICE assessment of the ASO devices implanted was performed off line. Results: The mean equivalent circle diameter predicted by ICE was 24.40 Ϯ 5.61 mm and was significantly higher (p ϭ 0.027) than the ASD measured by balloon sizing (21.38 Ϯ 5.28 mm). Unlike previous studies we did not find any correlation between the two measurements (correlation coefficient ϭ 0.47). Only four of the 13 patients had optimal device positioning as shown by the qualitative ICE evaluation, whereas the remaining nine patients had inadequate device placement. This resulted in a waist diameter that was an average 26.1% undersized in seven patients and 12.7% oversized in two patients. Five of the seven patients with an undersized device had ASO-atrial septum misalignment with leftward device deviation. Conclusion: The ICE images allowed careful measurement of the dimensions of the ASD and accurately displayed the spatial relations of the ASO astride the ASD. Moreover, use of the ICE measurement led to selection of a different size of device in comparison with those of balloon sizing. The clinical benefit of this new approach needs to be rigorously tested.
