NCT ID: NCT03894033 Recruiting - Aortic Dissection Clinical Trials

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

PROTECT
Start date: March 12, 2019
Phase:
Study type: Observational [Patient Registry]

The objective of this registry is to collect information on the performance and clinical benefits of the AMDS (Ascyrus Medical Dissection Stent) to treat patients with acute "DeBakey type I dissections" and with or without so called "preoperative clinically relevant malperfusion" and/or "intramural hematomas". In a healthy aorta (the vessel that supplies blood to most of the body) the blood flows freely through the main lumen (a space inside the vessel where blood flows). The participants involved in this study have a tear that has separated the inner layer of the aorta wall and created a secondary channel (false lumen) in addition to the main channel (true lumen), and huts, the blood flows through both channels. AMDS is a stent (a metal tube helping to keep the vessel open) that is placed in the descending thoracic aorta. AMDS is a medical device commercially available in the countries in which the study is being conducted and it is used as standard of care according to its indication.

NCT ID: NCT02860182 Recruiting - Clinical trials for Acute Type A Dissection

Mechanical Characterization of Ascending Aorta in Patients With and Without Aortic Dissection

Start date: January 2014
Phase: N/A
Study type: Observational

Acute type A aortic dissection is a frequent (3 cases per 100 000 people per year) and severe (spontaneous mortality 70%), needing an emergency surgical treatment. Surgical outcomes have improved with the development of surgical techniques, but the postoperative mortality remains high (15-30% at 30 days). Endovascular approach with the deployment of endoprosthesis sealing the proximal intimal tear is an attractive minimally invasive technique, which can represent an alternative to surgical repair especially in high risk patients.
