Objectives: To evaluate safety, efficacy, and technical advantages of Amplatzer™ Trevisio™ intravascular delivery system (ATIDS) in percutaneous atrial septal defect (ASD) closure in children.

Background: The Trevisio™ is a novel delivery system designed for accurate and facilitated implantation of Amplatzer™ devices. There are no published clinical reports so far.

Methods: During September 2020, 9 children with anatomically challenging ASDs underwent attempted transcatheter closure using ATIDS to deliver Amplatzer™ Septal occluders (ASO). All interventions were performed under general anesthesia, trans-esophageal echocardiography (TOE), and fluoroscopic guidance. Standard safety, immediate, and 60-days outcomes were prospectively assessed.

Results: The median age was 8.1 (5.1–16.9) years and the median bodyweight was 30 (18–63) kg. Six patients had isolated secundum-type ASDs with absent anterosuperior rims including one with an aneurysmal septum. Three patients had unclassical defects associated with complex congenital heart anomalies. Eight devices were delivered from the femoral vein and the jugular vein was accessed in one patient with interrupted inferior caval vein and azygos continuation. All implantations were successful. The shape, position, and orientation of the ASO were identical before and after release on TOE and fluoroscopy. There was no device embolization or serious complication following closure. Complete shunt closure was confirmed on follow-up.

Conclusions: We report the first clinical experience with ATIDS in transcatheter ASD pediatric closures. Safety and efficacy were witnessed in our case-series. The major advantage of reduced-tension deployment and reliable precision in device positioning is highly beneficial in challenging anatomies and unusual access.

Introduction

Since the first report of atrial septal defect (ASD) non-surgical closure in 1974, multiple occluders were tested in clinical studies (13). However, it was not until the Amplatzer™ Septal Occluder (ASO) became available in the mid-1990s that transcatheter ASD closure became a routine procedure (4). Today, the ASO remains the most widely used device with proven long-term efficacy and safety in adult and pediatric patients (5, 6). In some cases, implantation success may be limited by complex ASD anatomies with insufficient surrounding rims or limited venous access. New Amplatzer-like self-centering devices with modified delivery systems were developed by several manufacturers to overcome these difficulties but their behavior during implantation, and their medium-to-long-term performance is a subject of current debates (710). The ability of interventionists to tackle anatomically challenging defects has also progressed over time with substantial modifications in delivery techniques but was associated with increased procedural time, irradiation, and risk of complications (11, 12). The recently introduced Amplatzer™ Trevisio™ intravascular delivery system (ATIDS) for Amplatzer™ devices has an ultra-flexible delivery wire tip with promising technical advantages in terms of reduced-tension deployment and precise implantation. We report the first experience with the Trevisio™ delivery system in percutaneous ASD pediatric closures.

Materials and Methods

Study Design and Patients Selection

During September 2020, all consecutive pediatric patients with anatomically challenging ASDs and scheduled for attempted transcatheter closure using the new ATIDS to deliver Amplatzer™ Septal occluders (ASO) (AGA Medical Corp., MN, USA) at our institution were enrolled in this study and prospectively followed-up for 60 days. Written informed consent was signed by the patients' legal guardians to perform the procedure after they were provided with a comprehensive explanation about the procedural details. Permission was obtained from the manufacturer to use and mention their product in this submission. Standard safety, immediate and 1-month outcomes were assessed.

Catheter Procedure

All procedures were performed in the catheterization laboratory by an experienced pediatric interventional cardiologist under general anesthesia, fluoroscopic control, and transoesophageal echocardiography (TOE) guidance. Before the procedure, all patients underwent detailed protocol transthoracic echocardiography (TTE) assessment by an experienced pediatric operator to evaluate the physiology, to delineate the anatomy, defect margins, and the presence of associated anomalies, and to confirm the indication of closure (13, 14). At the start of the procedure, the same echocardiographer performed careful TOE evaluation. The ASD sizing was based on strict 2-dimensional TOE measurements in 3 different planes (0°, 35° to 55°, and 90° to 110° angles) without static balloon sizing technique. As per-institutional protocol, the size of the device was selected based on the largest diameter (3–4 mm larger in defects with adequate anterosuperior rim and 5–6 mm larger in defects with absent anterosuperior rims). The right femoral vein was routinely accessed using a 7-Fr short introducer and in case of anatomic limitations, the approach was transjugular. Intravenous cefazolin and heparin were given according to protocol. A 0.035-inch wire was placed in the left or right upper pulmonary vein through the ASD using a 5-Fr multipurpose or Judkins right diagnostic catheter (Cordis Corporation, FL, USA). In complex cases, the wire was positioned in the left ventricular outflow tract. All ASO were delivered using ATIDS and deployed under continuous fluoroscopic and TOE guidance. The device was released, once the correct position and absence of residual shunt and interference with other structures were confirmed by TOE. Standard potential adverse events were assessed. The procedure was considered successful only when the device was released into the desired position with no residual shunt or immediate device embolization. Procedural time and irradiation data were recorded. All patients received standard care of the venous access site. They were followed up at 1, 7, 30, and 60 days by clinical examination, electrocardiogram, and TTE with a focus on device position, the competence of the atrioventricular valves, and the absence of pericardial effusion. Aspirin therapy was prescribed for 6 months.

Amplatzer™ Trevisio™ Intravascular Delivery System

The ATIDS was recently introduced for the Amplatzer™ device family with promising enhanced deliverability. It leverages the one-piece cable design utilized by the Amplatzer™ TorqVue™ Delivery System, also known as the Classic Amplatzer™ Delivery System. The cable is designed with a stiff proximal section for no compromise on the torque strength, sheath diameter, and pushability. The flexible transition section stabilizes the position of the sheath during device deployment. The highly flexible wire-tip with the ultra-short screw reduces the bias on the device enhancing the assessment of device position before cable release (Figure 1A). These new flexibility features allow the distal part of the cable to easily tilt for more than a 90° angle optimizing the alignment of the device with the atrial septum during implantations (Figure 1B). The delivery system is shipped separately from the device with a 45° angle curvature sheath that is available in two lengths (60 or 80 cm). The ATIDS sheath size is exactly the same as used before, ranging from 6-Fr to 12-Fr. The body of the sheath is radiopaque for visibility under fluoroscopy. An ~0.25-inch long black mark is precisely positioned at 75.2 and 94.5 cm from the distal tip of the 110 cm- and 120 cm-long-cables in the 60 and 80 cm delivery systems, respectively (Figure 1A). It is added to inform the operator that when the marking reaches the Tuohy valve, the device is near the tip of the sheath.

Statistical Analysis

Categorical variables were reported as frequency and percentage and continuous variables were represented as median with total range as appropriate.

Results

Nine patients were included and their clinical characteristics are outlined in Table 1. The median age was 8.1 years (ranging from 5.1 to 16.9 years). Six patients had isolated secundum-type ASD with inadequate anterosuperior rim and heart dilatation (Figure 2A) including one with aneurysmal interatrial septum. One patient with surgically-corrected double outlet right ventricle and straddling mitral valve had left-to-right shunt across a residual ASD initially created by balloon atrial septostomy in the neonatal period and left untreated until the age of 5 years. Another patient with left isomerism, interrupted inferior caval vein, azygos continuation, surgically-repaired complete atrioventricular septal defect with 2 subsequent surgeries for regurgitation and stenosis of the right atrioventricular valve presented with exercise-induced oxygen desaturation and chronic migraines. She was diagnosed with bidirectional shunt across the surgically created-ASD that was initially left for residual mild tricuspid stenosis (Figure 3A). Another patient with a medical history of extreme prematurity, severe form of pulmonary bronchodysplasia, and large secundum-type ASD progressively developed pulmonary hypertension of mixed origin at the age of 2 years. She had aggressive medical treatment with satisfactory outcomes. Right superior pulmonary vein stenosis was diagnosed after 4 years and was treated with balloon dilation and repetitive stenting (Figure 4A). At the age of 17 years, the mean pulmonary pressures dropped to 25 mmHg and the left-to-right shunt across the ASD was significant (Qp/Qs = 1.8) with an indication of closure. Devices were delivered from the right femoral vein in 8 patients and the right jugular vein in one patient. Median procedural and fluoroscopic times were, respectively, 16 min (range, 8–40 min) and 4.9 min (range, 1.04–17.2 min). All devices were accurately and uneventfully delivered, positioned, deployed, into proper position. Device release was controlled and successful in all cases without any technical difficulty. No major complications occurred in any of the subjects. The 60-days follow-up confirmed complete shunt closure.

Discussion

The ASO continues to be the most widely used device for ASD closure because of its simple implantation process, wide range of sizes, and excellent occlusion rate. However, the original stiffer delivery wire of the ASO transferred considerable tension to the occluder and the atrial septum increasing the risks of device embolization and procedure failure especially in patients with suboptimal atrial morphologies (13, 14). A significant proportion of defects are neither central nor small, and these are more of a challenge for percutaneous closure. Deficiencies of the anterosuperior septum are common, especially in large defects. The common approach from the inferior caval vein means that the ASO will approach the atrial septum at an angle. It can be challenging to prevent the anterosuperior rim of the device from pulling from the left atrium into the right atrium before the core of the device can be developed. Technical modifications to tackle difficult anatomies were reported (11, 12). Modified deployment maneuvers included changing the orientation of the left atrial disk of the device within the left atrium or altering the deployment sequence by delivering the central core of the device slightly within the left atrium before bridging the device back to the septum, and in case of failure to deliver the left disk within the left or right upper lobe pulmonary vein. Modifications in implantation techniques also included the use of modified or steerable delivery sheaths and balloon-assisted closures (1517). However, all these maneuvers were associated with longer procedures, higher radiation, and an increased risk of complications (12, 14). Therefore, new titanium-coated devices were developed similar to the ASO but with modified delivery systems to overcome the aforementioned difficulties. The second-generation flex of Occlutech Figulla® septal occluder (Occlutech GmbH, Jena, Germany) was introduced in 2009 with improved delivery features (18, 19). The screw mechanism of the ASO was replaced by a ball-shaped connector design that allows a tilt angle up to 45° with better septum alignment during implantation. The system was even upgraded in the third-generation device (Flex II) to a bioptome-like innovative delivery system that comes along with a steerable catheter, allowing full circular movement of the device on the delivery wire and facilitating closure of larger or asymmetric defects (20, 21). However, this device carries 2 major drawbacks (7, 8). Difficulty in selecting the correct device size was reported as the device exists in 3 mm increments for sizes between 21 and 40 mm (7). The Occlutech device is manufactured using thicker diameter Nitinol wire as compared to ASO, requiring larger venous delivery sheaths for a device of equivalent size to the ASO. This is not a problem in adults but its use in children might be limited because of the risk of vascular damage (8). More recently, the CeraFlexTM ASD occluder (Lifetech Scientific, Shenzhen, China) was commercialized as an alternative device to the ASO with structural innovations including a pre-mounted delivery system with 360° flexible connection and minimized amount of implant material (22, 23). Astarcioglu et al. demonstrated comparable outcomes with the ASO with no procedural complications (23). He reported that the operator can evaluate the device's final position without tension from the delivery catheter, allowing safe placement and detachment with the lock/release mechanism. Nevertheless, reported clinical experience with CeraFlexTM ASD occluder is very limited with lacking long-term data about its safety (2224). The disadvantages of this device also include limited size options (19 vs. 27 sizes in ASO), and the requirement of a slightly larger delivery sheath than with ASO devices. A recent prospective concurrent head-to-head comparison of ASO with Ceraflex and Occlutech ASD occluders showed that the newly-modified structural designs do not show any advantages in terms of procedural complications and midterm follow-up outcomes (10). Georgiev et al. even showed that retrieval of Ceraflex and Occlutech ASD occluders larger than 16 mm was impossible in vivo and during benchside using standard snare techniques (9). The authors had to develop and test a new removal method using biopsy forceps which proved to be feasible in animal experiments. In contrast with the ASO, these technical difficulties in percutaneous device removal may be an important drawback for clinical application. On the other hand, always keep in mind that despite the great success of the ASO, the risk of erosion remains a safety caution, especially since it can be fatal and may occur several years after implantation (25). However, device erosion was also reported with many other newer devices (26, 27). It is here where the Carag Bioresorbable Septal Occluder (Carag AG, Baar, Switzerland) stands out here as a breakthrough novel device that advances septal occluder technology to a new level by eliminating the risks of perforation and valve distortion. Yet, no detailed technical data and clinical feedback have been published and only 3 sizes are available for defects up to 25 mm (25, 28).

The ATIDS was designed and developed by the Amplatzer manufacturers to deliver their devices with promises of increased procedural flexibility and deployment control. Our patients experienced successful implantations with no major complications during or after the procedure. The delivery system handled very well as device movement across the sheath was not affected by the new applied technologies. Based on our preliminary experience, this new design will enable interventionists to perform classic and complex ASD closures with complete ease and confidence. The recently added black marking on the cable enabled blind delivery of the device until the tip of the sheath, theoretically reducing fluoroscopic time. We noticed that the device was perfectly aligned with the septum in all cases (Figures 25). When the ASD had to be closed using the transjugular approach, ATIDS offered the major advantage of positioning the device in the plane of the septum without the use of a steerable introducer. The perpendicular orientation of the delivery system to the atrial septum was easily obtained with the ultra-flexible wire (Figures 3B,C). The flexible 3-dimensional flexibility with a tilt angle going up to 120° (Figures 4C,D) helped in conforming the ASO to the various septal anatomies, minimizing maneuvers, and possibly the post-occlusion para-prosthetic leaks. The increased flexibility on the wire tip decreased the tension created by the cable on the device and subsequently on the atrial septum. This reduced tension allowed a more controlled deployment sequence helping us in positioning the device more easily into the desired position and minimizing any unwanted drag or pull on the implant. However, the ability to retrieve and redeploy the disks for proper positioning was identical to the original delivery wire (previous center experience), allowing appropriate repositioning when necessary. The secure and stable device position within the defect can also be checked by the “Minnesota wiggle” (Figures 5C,D). The sheath only needs to be advanced toward the occluder to stabilize the ultra-flexible section of the cable and allow the push-pull manoeuver with complete security and confidence. Most importantly, the ATIDS, in comparison to the classic delivery system offered the major advantage of accurate assessment of device final position before cable release and therefore a more reliable TOE as well as TEE assessment of the device accommodation over the margins and the presence of a residual para-prosthetic leak (Figure 2). When the device is deployed into position, we recommend a clockwise rotation of the delivery sheath and a gentle push on the cable until the ultra-flexible wire-tip curves into a 45° to 90° angle (Figures 2B,C). These maneuvers will enable interventionists to benefit from the maximum flexibility of the Trevisio™ cable, eliminating the tension on the device that will conform to its final and definitive position (Figures 2D,G). The shape, position, and orientation of the device were strictly identical before and after release in all cases (Figures 2, 3, 5). The forecasting of device configuration before cable release will certainly help in improving procedural outcomes, especially in complex and unclassical cases.

Conclusion

The safety and efficacy of the newly developed ATIDS were described in our case-series of pediatric ASD transcatheter closures. The increased implantation flexibility and reduced tension during ASO positioning were remarkable as the definitive device position on the atrial septal wall was observed before cable release minimizing any unwanted drag or pull on the implant and improving procedure outcomes. With the enhanced maneuverability and flexibility, ATIDS will probably be beneficial in other types of percutaneous procedures such as ventricular septal defect and patent arterial duct closures.
