“…Sufficient data on this unique device are lacking. As well as we know there is only one published report that evaluates the performance of the device prospectively [9]. To the best our knowledge, this is the second study that evaluates the feasibility, safety and efficacy of the NOASD-R in ASD closure.…”

“…The appropriate-sized long sheath was placed into the LUPV in order to prevent the opening of the device within the left atrial appendage, as described [9]. If standard LUPV deployment technique was unsuccessful as the device not aligned perpendicularly to the septum and/or embolized into the right atrium, right upper pulmonary vein (RUPV) approach was used.…”

“…The NitOcclud Ò ASD-R (NOASD-R) (pfm Medical, Cologne, Germany) is a new device with unique characteristics in terms of the device structure and delivery system. Reported data on the NOASD-R are limited [9]. We evaluated 30 patients with secundum ASD who underwent cardiac catheterization with the aim of the device closure of ASD using NOASD-R to assess the safety and efficacy of the device.…”

We aim to assess the safety, feasibility and efficacy of the new Nit-Occlud ASD-R (NOASD-R) device. From 2014 to 2015, transcatheter closure of atrial septal defect (ASD) using the NOASD-R was performed in 30 consecutive patients. The standard deployment technique as the left upper pulmonary vein approach was used in 25 patients. Right upper pulmonary vein approach was required in five. The median age was 6 years (range 3.5-60 years), and median weight was 21.5 kg (14-79 kg). Implantation was successful in all patients. The median size of devices was 16 mm (12.0-26.0 mm). The mean device size/2D defect diameter ratio was 1.26 ± 0.09 (1.12-1.40). The mean device size/color flow diameter ratio was 1.07 ± 0.06 (range 1.0-1.22). Releasing problem was encountered in three patients. A device-related erosion on the day after the closure was observed in one patient. No further device-related complication (erosion, embolization or dislodgement of the device) was encountered in a median follow-up period of 10 months (range 2-14 months). Complete occlusion has occurred in all at follow-up. NOASD-R is a feasible and effective device for use in the transcatheter occlusion of moderate to large secundum ASDs in selected patients. The occurrence of the erosion on the right atrial roof may be due to the high localization of the device and the larger size of the right disk.

“…ASD is one of the most common congenital heart diseases, but it can be repaired by interventional treatment, which has the advantages of limited trauma, no scarring, no effects on appearance or recovery, relative safety, and yet can achieve the same results as more traditional surgical treatments [10]. With accumulating experience performing this treatment, along with improvements in the operation technique, even defects with small margins or rims can be successfully repaired using interventional treatment.…”

Objective: The aim of this work was to evaluate the feasibility and safety of transcatheter closure procedures for the treatment of atrial septal defects (ASDs) with insufficient rims. Methods: A total of 507 secondary ASDs were divided into two groups based on whether they had deficient rims or not (152 vs. 355 cases,respectively). Any complications, including residual shunt, heart arrhythmia, occluder translocation, etc., were followed up for 1-3 years. Results: There were no differences in gender, weight, exposure time, ECG states, pulmonary pressure, the intervention success rate, occurrence of residual shunt, the operation time and occurrence of residual shunt during follow-up between the two groups (p > 0.05). However, the occurrence of rhythm disorders was significantly different between the two groups; ASDs with deficient rims were at an elevated risk (p < 0.05). Specifically, there was a significantly higher incidence in the occurrence of arrhythmia in the deficient rims group at 24 h postoperation, but no differences in arrhythmia incidence at any of the other follow-up time points (1, 3, 6, 12 and 36 months; p > 0.05). Conclusions: Patients with deficient rims experience a high success rate of ASD intervention and low rate of complications when the procedures are performed by experienced operators.

“…Of 74 ASD patients (mean age 17.2 years [range 2-72]) with a mean device size of 18.9 mm (range 10-30), 73 patients had a successful closure [70]. The one failure was a patient in which device-induced complete heart block was observed, after which the device was removed.…”

Historical developments of atrial septal defect closure devices: what we learn from the past

Introduction: Since King and Mills' pioneering work in percutaneous closure devices of secundum atrial septal defects (ASD) four decades ago, developments in device shape, material and implantation technique led to adoption of percutaneous ASD closure as current treatment of choice. Not only was the feasibility of such a percutaneous procedure tested altogether, but pursuing the ideal device in terms of safety and efficacy became priority. Areas covered: In this review we present the historical development of ASD devices in design, material and technique with clinical data, and provide the future perspectives in percutaneous ASD closures. Expert opinion: An 'ideal device' requires complete defect closure with negligible risk of complications using a safe, straightforward delivery technique with repositioning and retrieving properties. Some of the devices currently at hand come close to fulfilling these criteria, however none seem to provide those prerequisites completely. By understanding how challenges in device development were overcome in the past, new insights into future improvements are given. ARTICLE HISTORY
