What this trial studies

This observational study aims to confirm the safety and performance of the AcuMark Sizing Balloon used in the closure of atrial septal defects (ASD). It will monitor patients who have been diagnosed with a single secundum ASD and are scheduled for closure procedures. The study will also identify and track any previously unknown side effects related to the device or the procedure itself. By gathering this data, the study seeks to enhance the understanding of the device's impact on patient outcomes.

Who should consider this trial

Good fit: Ideal candidates include patients diagnosed with a single secundum ASD who are scheduled for closure and can provide informed consent.

Not a fit: Patients with contraindications for ASD closure or those with specific types of ASD, such as ostium primum or coronary sinus ASD, may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the safety and effectiveness of ASD closure procedures for patients.

How similar studies have performed: While this study focuses on post-market follow-up, similar studies have shown success in monitoring device performance and safety, indicating a potential for valuable insights.
