Abstract
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.

Huang Y, Kong JF, Venkatraman SS. Biomaterials and design in occlusion devices for cardiac defects: a review. Acta Biomater 2014; 10:1088-101. [PMID: 24334144 DOI: 10.1016/j.actbio.2013.12.003] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2013] [Revised: 11/14/2013] [Accepted: 12/02/2013] [Indexed: 10/25/2022]
Abstract
This review examines the biomaterials used in occlusion devices for cardiac defects, and how the choice of these materials is dictated by design. Specifically, the devices used in three major applications, the atrial septal defect, the ventricular septal defect and the patent ductus arteriosus, are examined critically. A number of different devices are available, with varied performance in deployment and sealing. There is no device in any of the three categories that satisfies fully the range of requirements, and all have associated complications. The type and rate of complications are different among different devices. The short-term (immediate) complications are addressed by immediate retrieval. For longer-term complications, most of which can be fatal, currently only surgical retrieval and replacement are possible. Most of these longer-term complications can be alleviated by the use of fully degradable devices, which will eliminate concerns regarding the use of metals inside the heart, and if fully endothelialized, also minimize migration concerns. On the other hand, the lower moduli of currently available biodegradable materials need to be augmented. Improvements in the stiffness required for deployment can be accomplished with the use of fillers, nano- or micro-sized, and an example of this are radiopaque fillers.

Abstract
OBJECTIVES We sought to examine acute and midterm results of closure of multiple interatrial communications with staged device deployment and to review the relevant literature. BACKGROUND Information about percutaneous methods of closure for multiple defects is limited. METHODS We treated 148 patients with multiple defects. Of these, 88 had a relevant left to right shunt ("LRS"), 52 had a presumed paradoxical embolism ("PPE"), five had both (LRS and PPE), and one patient, respectively, had migraine, decompression sickness, and a right to left shunt. After implantation of the first device, closure of additional septal defects was attempted only if indicated clinically. RESULTS Ninety-four patients received a single device and 53 more than one. In four patients, surgical defect closure followed. At the end of follow-up (FU; mean 4.5 ± 3.4 years), complete closure of all defects occurred in 67.6% (62.1% for LRS, 76.5% for PPE). Clinical success (small or trivial residual shunt) was achieved in 86.9% (83.9% for LRS, 90.2% for PPE). Complications included pericardial effusions in 2.7%, recurrent thromboembolic events in 4.8%, and new onset of atrial fibrillation in 10.1%. In a significant number of patients with multiple defects, after single device implantation, the likelihood of complete closure increased with FU time (26% complete closure at 1 month vs. 78% at 24 months). CONCLUSION Percutaneous closure of multiple interatrial communications is feasible and safe. Importantly, many residual defects close without further intervention at FU. Therefore, staged device delivery is an alternative to simultaneous device implantation, possibly requiring fewer and smaller second devices.

Abstract
OBJECTIVES The aim of this study was to assess the mid-term safety and efficacy of percutaneous patent foramen ovale (PFO) closure using a bioabsorbable device (BioSTAR, NMT Medical, Boston, Massachusetts). BACKGROUND Closure of PFO in patients with cryptogenic stroke has proven to be safe and effective using different types of permanent devices. METHODS All consecutive patients who underwent percutaneous PFO closure with the bioabsorbable closure device between November 2007 and January 2009 were included. Residual shunt was assessed using contrast transthoracic echocardiography. RESULTS Sixty-two patients (55% women, mean age 47.7 ± 11.8 years) underwent PFO closure. The in-hospital complications were a surgical device retrieval in 2 patients (3.2%), device reposition in 1 (1.6%), and a minimal groin hematoma in 6 patients (9.7%). The short-term complications at 1-month follow-up (n = 60) were a transient ischemic attack in the presence of a residual shunt in 1 patient and new supraventricular tachycardia in 7 patients (11.3%). At 6-month follow-up (n = 60), 1 patient without residual shunt developed a transient ischemic attack and 1 developed atrial fibrillation. A mild or moderate residual shunt was noted in 51.7%, 33.9%, and 23.7% after 1-day, 1-month, and 6-month follow-up, respectively. A large shunt was present in 8.3%, 3.4%, and 0% after 1-day, 1-month, and 6-month follow-up. CONCLUSIONS Closure of PFO using the bioabsorbable device is associated with a low complication rate and a low recurrence rate of embolic events. However, a relatively high percentage of mild or moderate residual shunting is still present at 6-month follow-up.

Abstract
BACKGROUND Interventional closure of atrial septal defects (ASD) and surgical tunnel fenestrations in Fontan patients has become the procedure of choice for many years. Recently, the BioSTAR Occluder, a modification of the Starflex device with a resorbable matrix has become available. PATIENTS Ten Biostar devices were implanted in nine children with interatrial septal defects, one within a fontan baffle, eight with secundum atrial septal defects. The age of the patients ranged from 11 months to 17 years, the body weight ranged from 12.9-78 kg. RESULTS 10 BioSTAR devices were implanted in nine patients. In one patient, two BioSTAR devices were used to occlude multiple defects within the oval fossa. All defects were successfully and uneventfully occluded. Mean procedure time was 56 (range 28-125). Mean fluoroscopy time was 4.8 (range 1.1 to 13.0) min. None of the nine patients showed residual shunts after device implantation. After 30 days no shunt was seen in the control transthoracic echocardiography. No adverse effects like allergic reactions, tachyarrhythmia or thrombembolic events occurred in any of the patients. CONCLUSION The BioSTAR closure device is a safe and effective device for the closure of a variety of interatrial shunts in children including multifenestrated interatrial defects and fontan fenestrations, however, possible long term consequences (e.g., fractures, recurrent shunts after scaffold degradation) remain to be studied.

Abstract
We reviewed our experience using the Amplatzer septal occluder (AGA Medical, Golden Valley, MN, USA) to close large, secundum-type atrial septal defects (ASDs) in children. Between June 2002 and December 2005, 52 patients (mean age 13.5 +/- 8.7 years) underwent transcatheter closure of large (> or =25 mm), secundum ASDs with the use of the Amplatzer septal occluder (ASO). Groups 1 and 2 included patients with a retroaortic rim of <5 mm (n = 39) or > or =5 mm (n = 13), respectively. All procedures were performed with general anesthesia and transesophageal echocardiographic guidance except for 10 patients, which involved local anesthesia and three-dimensional transthoracic echocardiography. Successful device implantations, device sizes, approaches, complications, and closure rates were assessed. Device implantation was successful in 50 patients (96.1%), with no difference between groups (95% vs 100%, P>0.05). In 2 patients, implantation failed because of embolism or deployment failure. Device were larger in group 1 than in group 2 (29.7 +/- 4.2 vs 26.7 +/- 3.8 mm, P = 0.04). The right upper pulmonary-vein approach was more common in group 1 than in group 2 (P = 0.0001). Complications and closure rates did not differ between the groups (P > 0.05). Transcatheter closure of large, secundum ASD by using the ASO device was feasible, and complication rates were low. A deficient retroaortic rim did not preclude successful device implantation; however, a large device may be needed to close large ASD. Close long-term follow-up is necessary to determine the safety of transcatheter closure of large ASDs in children.

Abstract
Fenestrated atrial septal defects (F-ASDs) may pose a challenge to device closure; recently, a cribriform device with a minimal connecting intrawaist diameter and large, equal left- and right-sided discs has been designed to cover more than one adjacent defect. This study demonstrates the feasibility and technical aspects of closing F-ASDs using this new device. Sixteen patients between August 2003 and January 2006 were included in this study. The inclusion criterion was the presence of a F-ASD diagnosed by transesophageal echocardiography. One of the three available cribriform ASD device sizes (18, 25, or 35 mm) was implanted. Patients were followed for at least 1 year after the procedure. Thirteen patients had successful cribriform ASD device implantation (median age and weight, 12.5 years and 36 kg, respectively). Ten patients (62%) had an associated atrial septal aneurysm. The mean procedure time was 75.6 +/- 28.5 min and the mean fluoroscopy time 14.8 +/- 6.3 min. The RVEDD was significantly reduced, from a mean of 24.2 mm to 21.0 (p < 0.05). One patient developed atrial tachycardia requiring cardioversion during the procedure. There were no embolic events, heart block, or mortality. Complete closure was 10 of 13 (77 %) the next day and 12 of 13 (92%) at 6 and 12 months. We conclude that the cribriform Amplatzer device can be successfully and safely used in patients with F-ASDs. Complete closure may take up to 6 months.

Abstract
BACKGROUND A variety of transcatheter atrial septal defect (ASD) occluders are currently in use, the most commonly used device is the Amplatzer Septal Occluder (ASO) yet there is no perfect device. The Helex Septal Occluder is a new device (by W.L. Gore & Associates, Inc.) designed to improve the results of transcatheter ASD closure. We report our first experience in closing secundum ASDs with this new device after its recent modifications. METHODS Thirteen patients were selected for Helex device closure with median age of 8 years (2.5-44 years) and median weight 30 Kg (12-96 Kg). Inclusion criteria were: small to moderate Secundum ASDs with sufficient rims by transthoracic echo (TTE) and confirmed by transoesophageal echo (TEE). Two cardiologists carried out the decision of device size. One of the five available Helex ASD device sizes was used (15-35 mm). Follow up TTE was performed the next day, one month, six months and one year later. RESULTS Twelve patients had successful Helex septal occluder implantation. One patient was switched to Cribriform ASD device during the procedure because of failure of the locking mechanism. Two patients had trivial residual left to right shunt which disappeared at one month follow up in one patient. No embolic event, AV block or mortality was observed. CONCLUSION This feasibility study of the novel Helex septal occluder after its recent modification showed that it can successfully and safely close well selected secundum ASDs. There are several advantages over the currently available devices.

Abstract
Background—
The use of permanent synthetic implants to close atrial septal defects (ASD) and patent foramen ovale (PFO) has a number of limitations, including late complications and the limiting of transeptal access to the left heart should it be required for the later treatment of acquired heart disease. BioSTAR is a novel, bioabsorbable, atrial septal repair implant. This phase I pilot study evaluates the feasibility, safety, and effectiveness of BioSTAR for the first time in humans.
Methods and Results—
We conducted a prospective, open-label, multicenter clinical study in 58 patients aged 28 to 68 years who had a clinically significant ASD or PFO. Percutaneous shunt closure was undertaken with the BioSTAR septal repair implant. Successful device implantation was achieved in 57 (98%) of 58 patients. Closure at 30 days and 6 months, assessed by contrast transthoracic echocardiography, was 48 (92%) of 52 and 54 (96%) of 56, respectively. There was no evidence of a clinically significant response to the device. Transient atrial arrhythmia occurred in 5 patients after implantation. No major safety issues were observed.
Conclusions—
This study demonstrates the feasibility, safety, and effectiveness of BioSTAR for the closure of ASD and PFO in humans with a high rate of early and complete shunt closure. BioSTAR is a novel septal repair implant designed to provide biological closure of atrial-level defects using the patient’s natural healing response. Because 90% to 95% of the implant is absorbed and replaced with healthy native tissue, future access to the left atrium may be achieved.

Abstract
The availability of transcatheter devices has revolutionized the management of patients with congenital heart and vascular disease. Many patients that were in the past exclusively treated through open heart surgical procedures can now be managed using a percutaneous approach. This article describes those devices that are, at present, most frequently used in the USA for transcatheter therapy of congenital heart disease, which have, or are about to receive, US premarket approval. It also focuses on devices for occlusion of septal defects and vascular structures, as well as endovascular stents. In addition, the most important outcome data are discussed.

Abstract
OBJECTIVES This study sought to review the outcomes of 3 generations of closure devices for secundum atrial septal defects (ASDs) at a single institution. BACKGROUND Transcatheter closure of ASDs is now increasingly performed with devices that have been modified over time to improve performance. METHODS A review of prospective clinical trials of Clamshell (C.R. Bard Inc., Murray Hill, New Jersey), CardioSEAL (NMT Medical Inc., Boston, Massachusetts), and STARFlex (NMT Medical Inc.) closure devices for simple ASDs was performed. The entry criteria for these trials were age > or =2 years, isolated secundum ASD, evidence of right ventricular volume overload, and maximum stretched diameter varying from 20 to 25 mm. Successful outcomes were defined as no more than small residual leak (< or =2 mm) with absence of a severe complication or the need for an additional device or surgery. RESULTS A total of 72 Clamshell, 30 CardioSEAL, and 42 STARFlex devices were placed in uncomplicated ASDs. Each device modification resulted in improved closure rates, with the STARFlex device achieving a 93% complete closure rate with a device/stretched diameter ratio significantly smaller than with the other devices (p = 0.001). Severe complications occurred in 5 Clamshell, 1 CardioSEAL, and 0 STARFlex cases. Successful outcomes increased for each generation of device (79%, 93%, and 98% respectively, p = 0.009). There have been no long-term complications for either the CardioSEAL or the STARFlex devices. CONCLUSIONS Modifications in 3 generations of devices have resulted in improved results for percutaneous ASD closure.

Abstract
The work of the pioneers in PFO closure finally may evolve into a front-line therapy for secondary prevention of stroke in selected patients who have PFO and embolic events. Current implants, although new to most of interventional cardiology and neurology, are the result of years of steady, progressive work. It seems that PFOclosure is here to stay and will become a key element in a collaborative approach between cardiology and neurology in the treatment of embolic stroke. The advances in device technology may make PFO closure sufficiently safe, effective,and durable that it may become one of the most frequent catheter laboratory procedures to be performed.

Abstract
PURPOSE To describe the chest radiographic appearance of the Amplatzer septal occluder (ASO) (AGA Medical Corporation, Golden Valley, Minn) for atrial septal defects (ASDs) in pediatric patients. MATERIALS AND METHODS Two radiologists independently reviewed frontal and lateral chest radiographs obtained in young patients 24 hours after transcatheter ASD closure with the ASO. The appearance (flat disks or dots) and location of the ASO were recorded. The location was related to that of a thoracic vertebral body on frontal and lateral chest radiographs and to a line drawn between the anterior margin of the right hilum and the posterior margin of the inferior vena cava (hilar-caval line) on lateral radiographs; this line corresponded to the expected position of the interatrial septum. The relationship between ASO appearance and patient age was assessed with logistic regression and cumulative probability plots. RESULTS Sixty-eight pediatric patients (age range, 1 month to 18 years; mean age, 4.2 years; 24 boys and 44 girls) were included. On frontal radiographs, the ASO center projected between T7 and T9, either to the right of or over the spinous processes of the vertebral body. On lateral radiographs, the ASO projected over (n = 66) or anterior to (n = 2) the hilar-caval line. On frontal radiographs, it appeared as one or two flat disks (n = 61) or as two metallic dots (n = 7). On lateral radiographs, it appeared as two flat disks (n = 54) or as two metallic dots (n = 14). The relationship between increasing patient age and the metallic dot appearance on frontal and lateral radiographs and on the combination of frontal and lateral radiographs was highly significant in each case (P < .001, likelihood ratio chi(2) test), with r(2) values of 0.35, 0.20, and 0.28, respectively. ASDs were successfully occluded with the ASO in all patients except one, in whom trivial shunting was seen at 12-month follow-up. CONCLUSION The ASO in pediatric patients has a characteristic radiographic appearance when properly positioned.

Abstract
BACKGROUND The Amplatzer septal occluder (ASO) allows the percutaneous closure of small to very large atrial septal defects (ASDs). The CardioSEAL/STARflex (CS/SF) can be used only for closure of small to moderate ASDs (stretch size up to 18 mm). These 2 devices are widely used in clinical practice. Therefore, a comparison of their use in the closure of small to moderate ASDs is needed. METHODS From December 1996 to September 2002, 274 consecutive patients (mean age 20.3 +/- 17 years) underwent percutaneous closure of small to moderate ostium secundum ASDs. The CS/SF device was used in 121 patients, and the ASO was used in 153. RESULTS There were no differences in age, sex ratio, or pulmonary/systemic flow ratio. Stretch size of the defect was higher in the ASO group (13.6 +/- 3.5 mm vs 15.5 +/- 3.2 mm, P <.001). Procedure time and fluoroscopy time were shorter in patients treated with the ASO (61 +/- 21 vs 75 +/- 32 min, P <.0003, and 11.6 +/- 9 vs 23.8 +/- 17.4 min, P <.0001, respectively). Residual shunt at procedure and discharge was significantly more frequent in the CS/SF group (P <.0001). There were no differences in the complication rate for the 2 groups (CS/SF 4/121 vs ASO 6/153). Length of follow-up was longer in the CS/SF group (24 +/- 14 vs 16 +/- 9 months, P =.0001). Residual shunting was significantly more frequent in the CS/SF group during follow-up, while closure rate reached 100% after 1 month in ASO group. CONCLUSIONS The 2 devices are clinically safe and effective in ASD closure. However, percutaneous closure of small to moderate ASDs with ASO is quicker and provides an higher rate of complete occlusion.

Abstract
A 61-year-old woman presented with platypnea and orthodeoxia after right pneumonectomy for lung cancer. A perfusion lung scan taken after tracer injection in the sitting position showed an extrapulmonary uptake of radioactivity consistent with a right-to-left shunt. Such extrapulmonary uptake was no longer evident when tracer was injected in supine posture. The authors emphasize the value of perfusion lung scanning in the assessment of patients with unexplained dyspnea after thoracic surgery.

Abstract
BACKGROUND The Amplatzer Septal Occluder (ASO) (AGA Medical Corp, Golden Valley, Minn) has gained wide acceptance for transcatheter closure of atrial septal defect (ASD). We conducted this study to evaluate the short-and intermediate-term results of ASD closure with the ASO and to determine the impact of deficient rim on the results. METHODS Between March 1999 and February 2003, 197 patients underwent attempted transcatheter closure of ASD with the ASO. The size of the selected device either equaled or was 1 to 2 mm larger than the stretched diameter of the defect. Transesophageal echocardiography was used to monitor the implantation procedure. One hundred and fourteen patients (58%) with a deficiency in 1 rim (<5 mm) were included as group I, and the remaining 83 patients with adequate rims comprised group II. RESULTS The mean stretched diameter measured with the balloon catheter was 18.6 +/- 6.7 mm (range 7.1-37.2 mm). Deployment of the ASO was successful in 191 (97%) patients and failed in 6. There was no significant difference between the 2 groups in the success rate for ASD closure (110/114 vs 81/83). Repositioning of the device was required in 28 patients: 21 in group I and 7 in group II (21/114 vs 7/83, P >.05) The mean stretched diameter of the defect in these 28 patients was significantly larger than that in those who did not require repositioning of the device (27.3 +/- 5.7 vs 17.1 +/- 5.5 mm, P <.01). Three patients experienced severe complications: 1 had transient complete atrioventricular block, 1 had tamponade requiring drainage, and 1 had dislodgement of the device requiring emergent operation. One had a distal embolism to a fingertip. Echocardiography at 1 day, 3 months, 6 months, 12 months, and 24 months after the procedure showed residual shunts in 37/191 (19%), 15/189 (8%), 11/176 (6%), 7/131 (5%), and 3/72 (4%) patients, respectively. CONCLUSIONS The ASO is a safe and effective device for the transcatheter closure of ASD. Deficiency in 1 rim, particularly the superior anterior rim, does not influence the success rate of ASD closure.

Abstract
Background—
Our purpose was to describe a 13-year experience with patients undergoing transcatheter device closure of unrepaired congenital or postoperative residual ventricular septal defects (VSDs).
Methods and Results—
Since 1989, 170 patients (median age, 3.9 years) have undergone catheterization for closure of 1 or more congenital (n=92) or postoperative (n=78) residual VSDs using successive generations of STARFlex-type devices. Outcomes included echocardiographic assessment of residual flow and device position, assessment of VSD shunt/severity, and adverse events. Among 168 patients in whom device implantation was performed, between 1 and 7 devices were placed per patient (median, 1), with multiple devices placed in 40%. There was a significant decrease in left-to-right shunting after device implantation (
P
<0.001) and significant improvement in VSD size/severity, and device position proved stable. Of 332 adverse events, 39 were related to the device and 261 were related to the catheterization; all but 5 occurred in the periprocedural period. At a median follow-up of 24 months (0 to 154 months), 14 patients had died and 18 had device(s) explanted.
Conclusions—
Congenital and postoperative VSD closure using STARFlex-type devices resulted in stable improvement in clinical status and decreased interventricular shunting. Although periprocedural events occurred frequently, late events caused by the device were rare. Transcatheter device closure is an effective management option for patients with complex muscular VSDs that are difficult to approach surgically and for postoperative residual VSDs.

Abstract
Apart from closure of atrial septal defects, there is little information concerning the use of the CardioSEAL family of occluders in congenitally malformed hearts. We review here our initial experience using the CardioSEAL and STARFlex occluders in 12 patients aged 17.3 +/- 11.2 years, with a range from 4 to 34 years. Of the patients, 5 had fenestrated extracardiac Fontan procedures, 5 had persistent patency of the arterial duct, 1 had a leak across a Mustard baffle, and the final patient had a huge pulmonary arteriovenous malformation. We implanted successfully 9 CardioSEAL, and 3 STARFlex occluders, with sizes from 17 to 40 mm. In one patient, the occluder embolized to the right pulmonary artery, from where it was retrieved through the catheter. In two patients, there was a trivial residual leak immediately after implantation, but no patient had a residual leak after 6 months of follow-up. We noted improved ventricular dimensions, without any fractures of the arms of the occluders, perforations, or disturbances of flow after 2.4 +/- 0.9 years of follow-up. We have demonstrated, therefore, the versatility of the CardioSEAL and STARFlex occluders, which have been used safely and effectively to close a variety of intra and extracardiac communications other than atrial septal defects.

Abstract
OBJECTIVES The purpose of this study was to investigate the incidence, morphology, and clinical course of thrombus formation after catheter closure of intra-atrial shunts. BACKGROUND Post-procedure detailed information about thrombotic material on different devices for transcatheter closure is missing. METHOD A total of 1,000 consecutive patients were investigated after patent foramen ovale (PFO) (n = 593) or atrial septal defect (ASD) (n = 407) closure. Transesophageal echocardiography (TEE) was scheduled after four weeks and six months. Additional TEEs were performed as clinically indicated. RESULTS Thrombus formation in the left atrium (n = 11), right atrium (n = 6), or both (n = 3) was found in 5 of the 407 (1.2%) ASD patients and in 15 of the 593 (2.5%) PFO patients (p = NS). The thrombus was diagnosed in 14 of 20 patients after four weeks and in 6 of 20 patients later on. The incidence was: 7.1% in the CardioSEAL device (NMT Medical, Boston, Massachusetts); 5.7% in the StarFLEX device (NMT Medical); 6.6% in the PFO-Star device (Applied Biometrics Inc., Burnsville, Minnesota); 3.6% in the ASDOS device (Dr. Ing, Osypka Corp., Grenzach-Wyhlen, Germany); 0.8% in the Helex device (W.L. Gore and Associates, Flagstaff, Arizona); and 0% in the Amplatzer device (AGA Medical Corp., Golden Valley, Minnesota). The difference between the Amplatzer device on one hand and the CardioSEAL device, the StarFLEX device, and the PFO-Star device on the other hand was significant (p < 0.05). A pre-thrombotic disorder as a possible cause of the thrombus was found in two PFO patients. Post-procedure atrial fibrillation (n = 4) and persistent atrial septal aneurysm (n = 4) had been found as significant predictors for thrombus formation (p < 0.05). In 17 of the 20 patients, the thrombus resolved under anticoagulation therapy with heparin or warfarin. In three patients, the thrombus was removed surgically. CONCLUSIONS The incidence of thrombus formation on closure devices is low. The thrombus usually resolves under anticoagulation therapy.

Abstract
Transcatheter closure of single secundum atrial defects has become the standard of treatment. The purpose of our study was to analyze the results of using a single Amplatzer device for closure of double atrial septal defects. Such defects were diagnosed in 41 out of 363 patients with atrial septal defects (ASDs) closed by transcatheter method. In 39, a single Amplatzer device was used. The size of the larger defect ranged from 5 to 18 mm, the smaller defect from 2 to 7 mm, with the distance between the borders of the communications ranging from 2 to 12 mm. We performed sizing and closure of only the larger defect. The mean size of implanted devices was 16.5 +/- 5.5 mm, equal to the stretched diameter of the main defect or 1-4 mm larger. The closure rate assessed by color Doppler flow examination was 61% after 24 hr, 78% after 1 month, 83% after 3 months, 86% after 1 year, and 95% after 2 years. If the distance between the two defects exceeded 7 mm, residual leaks were observed but tended to decrease and disappear with time. Selected patients with double atrial septal defects can be effectively treated with implantation of a single Amplatzer device.

Abstract
INTRODUCTION Percutaneous closure of atrial septal defects (ASD) is becoming more frequent. PATIENTS AND METHOD From October 1997 to October 2002, 209 patients, age 0.4-70 (mean 19.5) years, were catheterized to close an ASD or patent foramen ovale (PFO). Transesophageal echocardiography was performed simultaneously in all patients. Two hundred and six patients had ASD (25 multiple ASDs) and 3 had PFO. Three devices were used, the Amplatzer Atrial Septal Occluder (ASO), CardioSeal (CS), and Starflex (SF). RESULTS Device implantation was achieved in 181 patients (87%) but had to be abandoned in 28 patients, generally because the ASD was too large. One hundred and seventy-four ASOs were implanted in 172 patients with ASD (2 ASOs were implanted in 2 patients with double ASD) and CS/SF in 9 patients (3 patients with PFO and 6 with ASD). The procedure was effective in 166/172 (96%) ASO implantations and in 8/9 (89%) CS/SF implantations. The procedure was unsuccessful in 7 patients and the device had to be removed (6 ASO and 1 SF). The occlusion rate with ASO was 88% after 24 hours, 91% after 1 month, 95% after 1 year, 97% after 2 years, and 100% after 4 and 5 years. All defects treated with SF/CS were closed successfully after 24 hours. In one case the ASO device was embolized to the aorta. In the first month after ASO implantation, supraventricular tachycardia appeared in 2 patients and transient left ventricular failure in 2 patients. No late complications were observed. CONCLUSION Percutaneous catheter closure of selected types of ASD using the Amplatzer Atrial Septal Occluder, CardioSeal, or Starflex should be offered to patients as non-surgical alternative. The type of device used depends on the defect size and morphology as well as the surgeon's experience. The presence of multiple defects does not exclude the possibility of a successful percutaneous catheter closure.

Abstract
AIM To evaluate the safety and efficacy of transcatheter closure of secundum atrial septal defects (ASD) with the Amplatzer septal occluder. METHODS 236 consecutive patients with a significant ASD (age 6 months to 46 years, median 5 years; body weight 6.5-79 kg, median 18 kg) were considered for transcatheter closure with the Amplatzer septal occluder; 18 patients with defects that were too large or with a deficient inferior margin were excluded from attempted transcatheter closure after initial transthoracic (4) or transoesophageal echocardiography (14). RESULTS At cardiac catheterisation, devices were not implanted in 18 patients because the stretched diameter of the ASD was too large (4), the device was unstable (4), compromised the mitral valve (1), or obstructed the upper right pulmonary vein (1); eight patients with additional systemic or pulmonary vein anomalies (5) or a Qp:Qs less than 1.5 (3) were excluded after angiographic and haemodynamic assessment. Thus ASD closure was done successfully in 200 patients (procedure time 25-210 minutes, median 66 minutes; fluoroscopy time 2.5-60 minutes, median 12 minutes), among whom 22 had multiple ASDs (14) or a septal aneurysm (8). The diameter of the devices ranged between 6-34 mm. Severe procedure related complications (retroperitoneal bleeding, air embolism) occurred in two cases. At follow up (33 days to 4.3 years, median 2.3 years) complete closure was documented in 94%, with a trivial residual shunt in 12 patients. CONCLUSIONS The Amplatzer septal occluder is very efficient and offered interventional ASD closure in 84.7% of our group of consecutive patients, with excellent intermediate results.

Abstract
OBJECTIVE To determine whether age has an effect on the long term outcome after surgical closure of atrial septal defects in patients aged 35 years and over. METHODS Retrospective analysis of 89 patients (64 women) operated on between 1989 and 1999. Patients were divided into two age groups: group I (aged 35-50 years, n = 51) and group II (> 50 years, n = 38). Follow up was between 1-11 years. RESULTS One operative death and two late deaths occurred in the study period (both in group II). Preoperatively, 29 (57%) patients were in New York Heart Association functional class III-IV in group I compared with 22 (58%) patients in group II (NS). After operation, 44 (86.2%) patients in group I were found to be in class I-II compared with 25 (71.5%, p < 0.05) in group II. Group I patients had a lower incidence of preoperative atrial fibrillation than those in group II (12 (23.5%) v 17 (43.6%), p < 0.05) and only four (7.8%) patients in group I were in atrial fibrillation requiring long term warfarin after surgery compared with 12 (34%, p < 0.05) in group II. Furthermore, echocardiography showed a greater reduction in right ventricular dimension in group I patients (mean (SD) 4.26 (0.82) v 2.71 (0.41) cm, p < 0.001) than in group II patients (4.36 (0.43) v 3.87 (0.29) cm, p = 0.21). No residual intracardiac shunts were identified during follow up. CONCLUSIONS Surgical closure of atrial septal defects in adult patients can improve clinical status and prevent right ventricular dilatation. The greatest benefit is seen in younger patients.

Abstract
We sought to evaluate the relative cost of surgical and device closure of atrial septal defect. Device closure for atrial septal defects is becoming an alternative to surgical closure. We examined the hospital-generated cost data in 13 patients who underwent surgical repair and 15 patients who underwent device closure of an atrial septal defects (ASD) or patent foramen ovale (PFO) during a prospective clinical trial of the device. The cost of device closure of ASD was 7,837 dollars less on average than surgical closure when the cost of the occlusion device was excluded (device closure cost 7,397 dollars +/- 2,822 dollars, surgical closure cost 15,234 dollars +/- 3,851 dollars; P < 0.001). When adjusted for a 5% failure rate of device closure, the cost savings was 7,076 dollars. Device closure of ASD results in substantial hospital-related cost savings that will be an important consideration once new devices are approved for clinical use.

Abstract
BACKGROUND The STARFlex (SF) device is a CardioSEAL (CS) double-umbrella device that has been modified by the addition of a self-centering mechanism comprised of nitinol springs connected between the two umbrellas and a flexible core wire with a pin-pivoting connection. This paper compares the results of atrial septal defect (ASD) closure with CardioSEAL and STARFlex devices. PATIENTS AND METHODS Between December 1996 and March 2000, 117 patients underwent ASD closure with CardioSEAL (n = 79) and STARFlex (n = 38). The mean age (17 years), weight (49 kg), and ASD size (15 mm) were similar in the two groups. The procedures were performed under general anesthesia with both fluoroscopic and transesophageal echocardiographic monitoring. IMMEDIATE RESULTS The devices were successfully implanted in all patients. Ten patients had multiple ASDs. A single device was used in four patients (CardioSEAL in three, STARFlex in one), while a simultaneous placement of two CardioSEAL (one patient) or two STARFlex (five patients) were performed in six patients. The results are summarized as follows: [table: see text] Follow-Up Results: On follow-up clinical exam, electrocardiograms, chest X-rays, and echocardiograms were obtained at 1, 6, and 12 months. [table: see text] During follow-up there were no deaths, endocarditis, rhythm disturbances, or other complications. Arm fractures were observed almost exclusively with large CardioSEAL devices (40 mm, less frequently with 33 mm), and only in one 33-mm STARFlex device. There were no clinical complications related to fractures. CONCLUSIONS The STARFlex device seems to offer better results than the CardioSEAL, with significantly lower rates of residual shunts and arm fractures.

Abstract
Paradoxical embolism through a patent foramen ovale (PFO) has been recognized as a potential cause of transient ischemia attack (TIA) and stroke especially in younger patients. The therapeutic options are medical treatment (antiaggregation or anticoagulation) with an annual recurrence rate of 3% to 4% for stroke or TIA, surgical PFO closure, or catheter closure. Randomized studies are ongoing; however, the results will not be available soon. Since August 1994, we have attempted catheter closure of a PFO in 281 patients (age 17 to 79 years, mean 46.8 +/- 13.2) with paradoxical embolism. Of these, 184 patients had at least one embolic stroke, 112 patients at least one TIA, and 15 patients at least one peripheral embolism. The diameter of the PFO, measured with a balloon catheter, ranged from 3 mm to 24 mm with a mean of 10 +/- 3.5 mm. Implantation of the occluder was technically successful in all patients (two attempts in four patients). Seven different devices were used: 26 Sideris buttoned, 11 ASDOS, 19 Angel Wings, 98 PFO-Star, 37 Cardioseal-Starflex, 57 Amplatzer and, 33 Helex devices. One patient suffered from septicemia and subsequently died. In 2 patients, device embolization occurred during or after the procedure (1 Sideris, 1 PFO-Star; catheter retrieval successful). Thirty-seven patients had other minor complications without long-term sequelae: atrial fibrillation within the first weeks after implantation in five patients, asymptomatic thrombus on the device at routine transesophageal echocardiogram (TEE) in 7 patients (1 Angel Wings, 1 ASDOS, 1 CardioSeal, 4 PFO-Star), and device frame fracture in 25 patients (2 Sideris, 4 ASDOS, 1 Angel Wings, 1 CardioSeal, 17 PFO-Star). No complications occurred with the newer devices (Amplatzer and Helex). A residual shunt after 6 months was found in 5.5% of the patients who had completed their 6-month TEE follow-up. In two patients, a second occluder was implanted because of a residual shunt. During a follow-up period of 1 month to 71 months (mean 12 +/- 16 months, 268 patient years), a recurrence of an embolic event (seven TIA, two stroke) occurred in eight patients. None of these occurred with the newer devices (Amplatzer, Helex). Freedom from recurrence of the combined end point of TIA, ischemic stroke, and peripheral embolism was 95.7% (95% CI: 89.0%-98.4%) at 1 year and 94.1% (95% CI: 80.1-98.4%) at 3 years. Catheter PFO closure is a technically simple procedure. With the newer devices and increasing experience, the success rate has improved and the complication rate has decreased. The advantage of the procedure is that closing the defect means a causal treatment. However, catheter closure of PFO despite a very low morbidity has inherent potential risks like any other interventional procedure. Furthermore, selection of patients who definitely have PFO as the cause of their cerebral event has not been defined. For these reasons, further studies are warranted.

Abstract
OBJECTIVE To apply three dimensional echocardiography to describe the geometric profile of the Amplatzer and Cardioseal occluders after deployment for closure of atrial septal defect. METHODS 20 patients (mean (SD) age, 14 (5) years) were enrolled for transcatheter closure of a secundum atrial septal defect with the Amplatzer occluder (10) or with the Cardioseal occluder (10). The two populations were matched for the stretched diameter of the defect (mean 18 (6) mm). The profile of the two occluders was examined. RESULTS Transoesophageal echocardiography did not show any residual shunts after Amplatzer occluder deployment, whereas three patients had a small residual leak after Cardioseal deployment. One patient had transient atrioventricular block with the Amplatzer device. The mean surface area of the Amplatzer occluder was 6.9 (2) cm(2), and that of the Cardioseal device 5.4 (3) cm(2) (p = 0.03). The mean volume of the Amplatzer occluder was 9.2 (1) cm(3), while that of the Cardioseal occluder was 3.5 (1) cm(3) (p < 0.0001). From the three dimensional views, the Cardioseal occluder looked like a flat square after deployment whereas the Amplatzer occluder took up a ball shape in the atrial cavity. CONCLUSIONS Three dimensional views by multiplane transoesophageal echocardiography allow a realistic in vivo description of atrial septal occluders. The Amplatzer occluder, with its high geometric profile, allows complete closure of large atrial septal defects but with some risk of mechanical complications. Use of the Cardioseal device, with its small surface coverage and high residual shunt rate, should be limited to transcatheter closure of a patent foramen ovale or small atrial septal defects.

Abstract
Over the past decade there has been increased use of transcatheter devices for closure of secundum atrial septal defects. The presence of a large eustachian valve complicating transcatheter closure has not been described. We describe four patients with prominent eustachian valves, in three of whom we employed a simple technique to obtain control of the eustachian valve during device placement using transesophageal echo guidance.

Abstract
The aims of these recommendations are to improve the outcome for patients after, and to provide acceptable standards of practice of therapeutic cardiac catheterisation performed to treat congenital cardiac disease. The scope of the recommendations includes all interventional procedures, recognising that for some congenital malformations, surgical treatment is equally as effective as, or occasionally preferable to, interventional treatment. The limitations of the recommendations are that, at present, no data are available which compare the results of interventional treatment with surgery, and certainly none which evaluate the numbers and types of procedures that need to be performed for the maintenance of skills. Thus, there is a recognised need to collect comprehensive data with which these recommendations could be reviewed in the future, and re-written as evidence-based guidelines. Such a review will have to take into account the methods of collection of data, their effectiveness, and the latest developments in technology. The present recommendations should, therefore, be considered as consensus statements, and as describing accepted practice, which could be used as a basis for ensuring and improving the quality of future care.

Abstract
In this review, we describe the experience from 13 European centres using the CardioSEAL and Starflex double umbrella devices to close interatrial communications within the oval fossa (so-called 'secundum' defects). Between October 1996 and April 1999, the procedure was attempted in 334 patients with a mean age of 12 years and a mean weight of 44kg. The mean measured stretched diameter of the defect was 15 mm. In the overall group, the defect was solitary in 245 patients (73%), multiple in 21 (6%), associated with an aneurysm of the flap valve in 15 (5 %), was represented by patency of the oval foramen in 44 (13%), and was a fenestration in a Fontan repair in 9 (3%). In all patients, the devices were inserted under general anesthesia, using fluoroscopic and transesophageal echocardiographic control. Implantation was achieved in 325 (97,3%). The device embolized within either a few minutes or a few hours in 13 patients (4%). Of these, uncomplicated surgical repair was undertaken in 10, while the device was retrieved in 3 using catheters and a second device was successfully implanted. Residual shunting was detected immediately after the procedure in 41% of the patients, with the incidence decreasing to 31% at discharge, 24% at 1 month, 21% at 6 months, and 20.5% at one year. During the period of follow-up, elective surgical repair became necessary in two patients, due to malposition of the device in one, and late embolization in the other. Fractures of arms were seen in 6.1 %, most commonly with the largest devices. All those with fractured arms of the device were asymptomatic, and no clinical complications related to the fractures were observed. There were no arrhythmias, endocarditis, valvar distortion, thromboembolic events, or other complications. After one year of follow-up, clinical success, defined as complete closure of the defect or presence of only a trivial leak, had been obtained in 92.5% of the patients. We conclude, therefore, that these devices produce excellent results when used to close defects of small to moderate size. Results are less than optimal, or else complications ensure, when attempts are made to close very large defects.

Abstract
Several investigations have been performed to evaluate the mid-term results of coil embolization for patent ductus arteriosus. Excellent results were obtained with coils if the minimum diameter of the ductus was less than 4 mm. Balloon dilation of native coarctation and recoarctation may be associated with complications such as aneurysm formation. Stent placement may solve some of the problems of balloon dilation, but the stents currently available are not perfect. Results of transcatheter closure of atrial septal defect using new devices have been were reported. The self-expanding nitinol double-disk device (Amplatzer septal occluder) (AGA Medical Corporation, Golden Valley, Minnesota) is becoming popular because it is easy to implant, is easy to retrieve before its release, can occlude a relatively large defect, and has a low rate of residual leak. Although the immediate results with this device were excellent, surgical closure is still the standard treatment and we need to see the long-term results of transcatheter closure.
