Design outcomes

Primary

MeasureTime frame
The occurrence of at least one episode of symptomatic or asymptomatic atrial fibrillation, atrial flutter, or atrial tachycardia lasting 30 seconds or longer within 30 days after PFO closure. Monitoring will be conducted using a 14-day Holter ECG with the AT Patch during the initial 14 days, followed by an additional clinical assessment and ECG evaluation on day 15.

Secondary

MeasureTime frame
The rate of at least one episode of atrial fibrillation lasting more than 30 seconds is monitored using an AT Patch 14-day Holter electrocardiogram, followed by additional clinical evaluation and electrocardiogram confirmation 15 days later.;The rate of at least one episode of atrial flutter lasting more than 30 seconds within 30 days is monitored using an AT Patch 14-day Holter electrocardiogram, followed by additional clinical evaluation and electrocardiogram confirmation 15 days later.;The rate of at least one episode of atrial tachycardia lasting more than 30 seconds is monitored using an AT Patch 14-day Holter electrocardiogram, followed by additional clinical evaluation and electrocardiogram confirmation 15 days later.;The rate of at least one episode of atrial fibrillation lasting more than 360 seconds within 30 days is monitored using an AT Patch 14-day Holter electrocardiogram, followed by additional clinical evaluation and electrocardiogram confirmation 15 days later.;The rate of at least one episode of atrial flutter lasting more than 360 seconds within 30 days is monitored using an AT Patch 14-day Holter electrocardiogram, followed by additional clinical evaluation and electrocardiogram confirmation 15 days later.;The rate of at least one episode of atrial tachycardia lasting more than 360 seconds within 30 days is monitored using an AT Patch 14-day Holter electrocardiogram, followed by additional clinical evaluation and electrocardiogram confirmation 15 days later.;The rate of at least one episode of atrial fibrillation lasting more than 30 seconds is monitored using an AT Patch 3-day Holter electrocardiogram.;The rate of at least one episode of atrial flutter lasting more than 30 seconds is monitored using an AT Patch 3-day Holter electrocardiogram.; The rate of at least one episode of atrial tachycardia lasting more than 30 seconds is monitored using an AT Patch 3-day Holter electrocardiogram.;The rate of at least one episode of atrial fibrillation la
