Outcomes
Primary Outcomes
Leakage rate at 6 month post-procedure measured by ultrasound
Time Frame: 6 months
The heart defects should be totally closed by the patch. Any residual flow or leakage, measured by ultrasound, will be recorded. The percentage of the patients that show leakage post-procedure is the failure rate. The study is considered achieved its primary endpoint if the failure rate of the test device is non-inferior to the rate of the comparator device.
Secondary Outcomes
No secondary outcomes reported
