Stent placement for thoracic aorta problems in urgent high-risk patients
This trial studies a new type of stent graft placed in the chest aorta (from the aortic arch into the descending part) to treat aneurysms or dissections in people who are too high-risk for open surgery. It may help by offering a faster, less invasive repair when waiting for a custom stent would be unsafe.

This trial tests a special stent (DERIVO) for brain aneurysms that have come back after earlier treatment. It's for people who cannot have other treatments like coiling or surgery.
Saint PetersburgAges 18 years+ - NCT03588286Recruiting
Check heart rhythm risk early after a heart attack
This trial tests whether a programmed heart rhythm test can better identify who needs an implanted defibrillator (ICD) soon after a heart attack. It may help prevent dangerous fast heart rhythms (tachyarrhythmias) by guiding who gets an ICD.
Boston, MassachusettsAges 18–85 - NCT04754659Recruiting
Checking kidney function after EVAR stent graft for aneurysm
This study looks at how a stent graft treatment for an abdominal aortic aneurysm affects kidney function over time. It may help doctors choose the safest approach for people whose aneurysm is treated with a procedure called EVAR.
