What this trial studies

This observational study aims to gather real-world clinical data on the safety and performance of the Zenith Alpha Thoracic Endovascular Graft (ZTA) for treating thoracic aortic aneurysms and penetrating aortic ulcers. It includes both retrospective and prospective patients, with retrospective data collection starting from January 2019 until the site is eligible for prospective enrollment. The study will help understand the long-term clinical outcomes associated with the device's expected lifetime.

Who should consider this trial

Good fit: Ideal candidates for this study are patients who have been treated or intended to be treated with the Zenith Alpha Thoracic Endovascular Graft since January 2019.

Not a fit: Patients who have received a custom-made fenestrated or branched endovascular graft in conjunction with ZTA may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term safety and effectiveness of the ZTA device for patients with thoracic aortic conditions.

How similar studies have performed: Other studies have successfully gathered real-world data on similar endovascular devices, indicating that this approach is supported by prior research.
