Combination treatment for long-standing persistent atrial fibrillation

This study compares two types of ablation (a procedure that uses energy to fix irregular heartbeats) for people with persistent atrial fibrillation. It tests whether adding extra treatment to the back of the heart's left upper chamber helps improve outcomes compared to standard treatment alone.

This trial compares two catheter ablation techniques for people with persistent atrial fibrillation (a type of irregular heartbeat that doesn't go away on its own). It will test whether a more extensive ablation (burning more heart tissue) works better than the standard procedure of isolating the pulmonary veins (the veins that bring blood from the lungs to the heart). If you have this condition and have had at least one episode in the past year, this study might help you find a more effective treatment.

This trial is testing a specific approach to catheter ablation for people with persistent atrial fibrillation. It aims to improve how abnormal heart tissue is targeted to help restore a normal rhythm.

This study compares two procedures to treat persistent atrial fibrillation (an irregular heartbeat that lasts more than a week). It looks at whether a newer method (pulsed-field ablation) works better than the standard method (radiofrequency ablation), both combined with a chemical injection to improve treatment success.

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.

This trial tests a catheter ablation procedure for people with persistent atrial fibrillation (a type of irregular heartbeat that lasts more than 7 days but less than a year). It aims to see if the procedure is safe and effective for restoring a normal heart rhythm.
