Study of a new catheter system for treating atrial fibrillation
This trial tests a new catheter and mapping system designed to treat paroxysmal atrial fibrillation (AF), which is a type of irregular heartbeat that comes and goes. If you have this condition, the study aims to see how well the new system works with a minimally invasive procedure.
Jonesboro, ArkansasAges 18–80 - NCT06828939Recruiting
Balloon treatment for atrial fibrillation
This trial tests a new balloon device that uses gentle energy pulses to treat atrial fibrillation (AF), a type of irregular heartbeat. It may help people whose AF has not improved with medication.
Prague, Czech RepublicAges 18–75 - NCT05227053Recruiting
Cryoablation study for paroxysmal atrial fibrillation after approval
This study looks at outcomes after a specific heart procedure called pulmonary vein isolation done with a cryoablation catheter. It is for adults with symptomatic “paroxysmal” atrial fibrillation who are planning this exact procedure.
Anchorage, AlaskaAges 18 years+ - NCT05794464Recruiting
Safe tracking registry for people with Afib
This registry is collecting health information from people with atrial fibrillation (Afib) who are being considered for a procedure to restore normal rhythm. It aims to better understand safety and outcomes so future care can be improved.
Ostrava, Moravian-Silesian RegionAges 18 years+ - NCT06392932Recruiting
Esophageal temperature monitoring during heart ablation
This study tests a new way to monitor the temperature in your esophagus during a standard heart ablation procedure for atrial fibrillation. The goal is to see if the new catheter (Q-DOT Micro) safely heats the heart tissue without harming the esophagus.
Los Angeles, CaliforniaAges 18 years+ - NCT07421076Recruiting
Grid mapping study for atrial fibrillation ablation
This trial tests a new mapping tool to help doctors find and treat the source of atrial fibrillation (AF) during a standard ablation procedure. It may offer a more precise way to guide treatment for people with AF that comes and goes.
Jinan, ShandongAges 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+ - NCT06618417Recruiting
Home sleep test for sleep apnea in atrial fibrillation
This study is using a smartphone app and a home sleep test to see if checking for sleep apnea helps people with atrial fibrillation feel better and have fewer heart rhythm episodes. The goal is to make monitoring easier for you at home.
