Jonesboro, ArkansasAges 18 years+ - NCT05951101Recruiting
Device to close an irregular heartbeat heart pocket safely
This trial tests the Zenith system, a device that seals off a heart area called the left atrial appendage to reduce stroke risk in people with atrial fibrillation (AF). You may be eligible if you have AF and a doctor recommends LAA closure, and you can return for follow-up scans and visits.
Parkville, VictoriaAges 18 years+ - NCT06007872Recruiting
Heart device implant using ultrasound probe inside the heart
This trial studies a procedure to implant a Watchman device using a tiny ultrasound probe placed inside the heart, avoiding a probe in the throat. It may help patients with atrial fibrillation who need to reduce stroke risk.
Cleveland, OhioAges 18 years+ - NCT06099106Recruiting
Testing a new device to close the left atrial appendage in AFib
This trial tests a new device called ENDOMATIC SEPIOLA that closes a small pouch in your heart (the left atrial appendage) to lower your stroke risk. It is a non-surgical option for people with atrial fibrillation who cannot take blood thinners.
TbilisiAges 18 years+ - NCT06436924Recruiting
Safety of high-volume day procedures for left atrial appendage occlusion
This trial studies whether having many left atrial appendage closure (LAAO) device implant procedures on the same day by one doctor is safe and effective. If you are scheduled for this procedure, you may be able to join.
Birmingham, AlabamaAges 18 years+ - NCT06585228Recruiting
Heart CT vs ultrasound to find clots after stroke
This study compares two ways to look for blood clots in the heart after a stroke: a heart CT scan and an ultrasound done through the food pipe. It aims to see if the CT scan can spot clots just as well as the more invasive ultrasound.
Amsterdam, North HollandAges 18 years+ - NCT05660811RecruitingPhase 4
Antiplatelet medicines after left atrial closure in dialysis patients
This trial looks at the best blood-thinning (antiplatelet) plan after a left atrial appendage closure procedure in people with kidney failure on dialysis. It may help reduce stroke risk while also lowering medicine-related side effects.
Warsaw, Masovian VoivodeshipAges 18 years+ - NCT04559243Recruiting
Left atrial appendage closure to prevent stroke in AF
This study tests whether closing a heart pocket called the left atrial appendage can lower future stroke or other clot-related events in people with atrial fibrillation. It’s mainly for people who have had a prior clot-related event or are at higher risk but may not be good candidates for long-term blood thinners.
Jinan, ShandongAges 18 years+ - NCT06802965Enrolling by invitation
Shanghai atrial fibrillation patient registry study
This study tracks people in Shanghai who have been diagnosed with atrial fibrillation (AF, a heart rhythm condition). By joining a registry, researchers can learn more about how AF is managed over time in the local population.
ShanghaiAges Any age - NCT07385599Recruiting
Study of a new heart device for atrial fibrillation patients
This trial tests a new device called LAmbre™ II that closes off a part of the heart called the left atrial appendage to help prevent strokes in people with atrial fibrillation who cannot take blood thinners.
ShatinAges 18 years+ - NCT07620262Recruiting
Combined atrial fibrillation treatment and stroke prevention study
This study tests a new approach for people with atrial fibrillation (a type of irregular heartbeat) who are also at high risk for stroke. It combines a procedure to fix the heart's electrical signals with closing off a small pouch in the heart to reduce stroke risk, potentially avoiding long-term blood thinners.
