Primary Outcome Measures

Name	Time	Method
Efficacy	60 months	A calculation of the proportion of subjects with clinically successful defect closure as determined by the site at 1, 3, and 5 years postprocedure.; Clinical Success is a composite measure of safety and efficacy evaluated at the 12-, 36-, and 60-month post-procedure evaluations and is defined as absence of: * Any major device/procedure adverse event; * Repeat procedure to the target ASD. Repeat procedures were considered major adverse events and are included in the major adverse event group.; * Clinically significant leak at the follow-up visit
Safety	5 years	A calculation of the proportion of subjects experiencing one or more major device or procedure related adverse event(s) at 1, 2, 3, 4, and 5 years post procedure.
