- NCT07783984Recruiting
Comparing two procedures for persistent atrial fibrillation with enlarged left atrium
This study compares two procedures to treat persistent atrial fibrillation in people whose upper left heart chamber is enlarged: catheter ablation (a minimally invasive procedure using a tube through a vein) versus thoracoscopic ablation (a surgical approach using small chest incisions). The goal is to see which method better restores a normal heart rhythm.
Seoul, SeoulAges 19 years+ - NCT07626411RecruitingPhase 3
Blood Thinner Study for Irregular Heartbeat
This study tests a new blood thinner to prevent strokes and blood clots in people with atrial fibrillation (a common heart rhythm problem). You may qualify if you have atrial fibrillation and at least one risk factor for stroke, or if you've never taken a blood thinner before.
Dothan, AlabamaAges 18 years+ - NCT06938412Recruiting
Exercise and Fitbit for Afib patients
This study tests whether using a Fitbit activity tracker and a supportive exercise program helps people with AFib become more active. It may help you feel better and manage your heart rhythm.
New York, New YorkAges 18 years+ - NCT07621003Recruiting
PULSed Field Ablation for New-Onset Atrial Fibrillation
This study tests a newer ablation technique using pulsed electrical energy to treat atrial fibrillation (an irregular heartbeat). You may qualify if you were recently diagnosed with AF and haven't had ablation before.
Bad OeynhausenAges 18 years+ - NCT07772518Recruiting
Comparing two guidance methods for pulsed field ablation in atrial fibrillation
This trial compares two ways of guiding a procedure to treat atrial fibrillation (an irregular heartbeat). One uses special sound waves to see inside the heart, and the other uses electrical mapping. Both are used with the FARAPULSE system to deliver a type of energy called pulsed fields to fixed areas of the heart.
ZagrebAges 18 years+ - NCT07116525Recruiting
Study of heart mapping for abnormal rhythms
This trial tests a special catheter to map abnormal heart rhythms like ventricular tachycardia or atrial fibrillation. It may help patients who need a procedure to find and treat the source of these fast or irregular heartbeats.
BrugesAges 18 years+ - NCT07106970Recruiting
Comparing two ablation approaches for persistent atrial fibrillation
This trial tests whether adding extra ablation lines to the standard pulmonary vein isolation procedure is more effective for people with persistent atrial fibrillation that hasn't been helped by medications. The goal is to improve symptoms like palpitations, fatigue, and shortness of breath.
BeijingAges 18–80 - NCT07316270Recruiting
Catheter ablation for atrial fibrillation after brain bleeding
This trial studies a procedure called catheter ablation to treat atrial fibrillation (an irregular heartbeat) in people who have had a brain hemorrhage. The procedure aims to reduce stroke risk and improve heart rhythm without increasing bleeding risk.
Hefei, AnhuiAges 18 years+ - NCT07575269Recruiting
New ablation treatment for irregular heartbeat
This trial tests a new tool called FARAFLEX that uses pulsed electrical energy to treat atrial fibrillation (an irregular heart rhythm). The goal is to see if this method can safely stop AF symptoms in people whose medications haven't worked.
Jonesboro, ArkansasAges 18 years+ - NCT06823778Recruiting
Preventing irregular heartbeat after heart surgery with radiofrequency
This trial tests whether using radiofrequency energy to isolate a small area in the heart's left upper chamber can prevent a common irregular heartbeat (atrial fibrillation) after heart surgery.
Moscow, MoscowAges 18 years+ - NCT06523738Recruiting
Studying heart size changes after shock and ablation for AF
This trial looks at how the size of your heart's upper-left chamber (left atrium) changes after a procedure to restore a normal rhythm (cardioversion). It aims to see if these changes can predict whether atrial fibrillation (AF) will come back after a later procedure called radiofrequency ablation.
Chongqing, Chongqing MunicipalityAges 18 years+ - NCT06061978Recruiting
Pacing after a heart procedure for rapid atrial fibrillation
This trial studies whether a special type of pacing (stimulating the heart's natural electrical system) works better than standard pacing after a procedure to control very fast heart rhythms. It's for people who already have a pacemaker and are getting a specific treatment for atrial fibrillation.
CaenAges 18 years+ - NCT04432220RecruitingPhase 4
Taking blood thinners one year after atrial fibrillation ablation
This study looks at whether people who have stayed in normal rhythm one year after atrial fibrillation ablation should continue blood thinning treatment. It may help guide safer, more personalized choices about long-term blood thinners after a successful procedure.
SeoulAges 19–80 - NCT06516822Recruiting
Comparing two ablation methods for long-standing atrial fibrillation
This study tests whether adding extra scar lines (linear ablation) to the standard pulmonary vein isolation (CPVI) is better than CPVI alone for people with long-standing persistent AF that has lasted 1 to 3 years. The goal is to see which approach reduces AF better.
Beijing, Beijing MunicipalityAges 18–75 - NCT07453940Enrolling by invitation
Closing off heart pouch with or without pulsed energy in atrial fibrillation
This study tests if adding a special energy treatment (pulsed field ablation) to a standard heart pouch closure is safe and works better for people with persistent atrial fibrillation who have few symptoms but a high risk of stroke.
Hangzhou, ZhejiangAges 18 years+ - NCT07523750Recruiting
Comparing two catheter treatments for persistent atrial fibrillation
This study compares two different catheters that use pulsed field ablation to treat a type of irregular heartbeat called persistent atrial fibrillation. The goal is to see which one works better and is safer.
Phoenix, ArizonaAges 18–80 - NCT07349121Recruiting
Testing the Farapulse and Watchman devices together
This trial is for people who need both a special heart treatment called pulsed field ablation (FARAPULSE) and a device to close off a small pouch in the heart (WATCHMAN FLX Pro or WATCHMAN FLX) to prevent strokes. The study will see how well both procedures work when done together.
AalstAges 18 years+ - NCT07738523RecruitingPhase 2/Phase 3
Caffeine and heart rate control in permanent atrial fibrillation
This trial tests whether stopping caffeine for up to two months helps control heart rate in people with permanent atrial fibrillation. If you drink at least one cup of caffeinated coffee a day, you may be able to join and help find out if giving up caffeine improves your heart rate.
Getafe, MadridAges 18–80 - NCT07217067RecruitingPhase 2
Study of PKN605 for people with atrial fibrillation
This trial tests a new medicine called PKN605 for people with atrial fibrillation (irregular heartbeat). The goal is to see if it can safely help control heart rhythm. You will need to have had at least two AF episodes recently and meet other heart health criteria.
Tupelo, MississippiAges 18 years+ - NCT07227532Recruiting
Testing a new catheter for atrial fibrillation treatment
This study tests a new catheter system, called Varipulse, to see if it's safe and effective for treating atrial fibrillation (AF), a heart rhythm problem. People with short-lasting AF who haven't been helped by medication may be able to join.
Phoenix, ArizonaAges 22 years+ - NCT07734194Recruiting
Studying a new sedation combo for afib treatment
This trial tests a mild sedation method using remimazolam and fentanyl during a procedure called pulsed-field ablation for atrial fibrillation (afib). It aims to find a safe and effective way to keep you comfortable without deep sedation.
PragueAges 18 years+ - NCT07728539Recruiting
Comparing a faster ablation method for atrial fibrillation
This study compares a newer, faster type of ablation (high-power short-duration) with the standard approach for treating atrial fibrillation. The goal is to see which method is safer and more effective at restoring a normal heart rhythm.
MoscowAges 18–70 - NCT07726056Recruiting
Heart ablation in athletes with atrial fibrillation
This trial tests if a heart procedure (cardiac ablation) helps endurance athletes who have atrial fibrillation (an irregular heartbeat) perform better in sports. Athletes will track their training data before and after the procedure to see if their performance improves.
MelbourneAges 18–80 - NCT07724899Recruiting
