The objectives of the study are:
* To determine the efficacy of the Figulla Flex II device compared with that of the Amplatzer ASO device for transcatheter closure of secundum atrial septal defects
* To determine the safety of the Figulla Flex II device compared with that of the Amplatzer ASO device for transcatheter closure of secundum atrial septal defects
This is a randomized, controlled, multi-centre trial of the efficacy and safety of the Occlutech septal occluder (Figulla Flex II) compared to the AGA septal occluder (Amplatzer ASO) for transcatheter closure of secundum atrial septal defects in patients.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring
1
Efficacy: the rate of a successful placement of the device
Timeframe: the day after procedure but no later than 36 hours after the procedure.
2
Efficacy:The secondary efficacy endpoint is the rate of closure success (residual shunt is smaller than or equal to 2 mm) within 6 months after the procedure, without the need for surgical repair.
Timeframe: within 6 months after the procedure
3
Efficacy:Other efficacy endpoint was the rate of complete closure (no residual shunt) at 6 months after the procedure.
. Willing to return for the post-treatment evaluation
Exclusion criteria
. Has multiple defects which can't adequately be covered by the device
. Has associated congenital cardiac anomalies which require cardiac surgery
. Patient is currently participating in another clinical device or drug trial that has not completed its primary endpoint or that will clinically confound the current study endpoints or does not permit subjects to participate in other studies. Typically, subjects that are involved in the long-term surveillance phase of a clinical study are eligible.
. Has ostium primum atrial septal defects
. Has sinus venosus atrial septal defects
. Has partial anomolous pulmonary venous drainage
. Has pulmonary vascular resistance above 7 Woods units or a right-toleft shunt at the atrial level with a peripheral arterial saturation less than 94%
. Has a recent myocardial infarction, unstable angina and decompensated congestive heart failure (CHF)
