Registry for the AMDS treatment of acute DeBakey type I aortic dissections

Post-market Registry of the AMDS for the Treatment of Acute DeBakey Type I Dissection: PROTECT Registry

Observational JOTEC GmbH · NCT03894033

This study is collecting information on how well the Ascyrus Medical Dissection Stent works for patients with acute DeBakey type I aortic dissections to see if it helps improve their treatment outcomes.

What this trial studies

This registry aims to collect data on the performance and clinical benefits of the Ascyrus Medical Dissection Stent (AMDS) in treating patients with acute DeBakey type I aortic dissections, including those with preoperative malperfusion and intramural hematomas. The study is observational and will gather information from up to 300 patients across 30 sites in Europe and Canada. Physicians will document their observations during routine care, and informed consent will be obtained from patients for the use of their clinical records. The registry is a continuation of previous efforts to evaluate the AMDS and aims to enhance understanding of its effectiveness in clinical practice.

Who should consider this trial

Good fit: Ideal candidates for this registry are adults aged 18 to 80 who have been diagnosed with acute DeBakey type I dissection or intramural hematoma within the last 14 days.

Not a fit: Patients with uncontrolled infections, severe allergies to necessary materials, or those in critical condition may not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could provide valuable insights into the effectiveness of AMDS, potentially improving treatment outcomes for patients with acute aortic dissections.

How similar studies have performed: Other studies have shown promise in using similar stent technologies for aortic dissections, but this specific registry approach is relatively novel.
