All recruiting trials (4)
-
nano-second pulsed field (nsPFA) catheter ablation for paroxysmal atrial fibrillation using the CellFX system
The study will try the CellFX nano-second pulsed field catheter to treat adults with recurrent, drug-resistant paroxysmal atrial fibrillation.
-
CellFX nsPFA cardiac surgery clamp for atrial fibrillation during heart operations
We will test a nanosecond pulsed field ablation (nsPFA) clamp used during heart surgery to see if it reduces atrial fibrillation in adults having other cardiac procedures.
-
Using a new catheter system to treat atrial fibrillation
This study is testing a new catheter system to see if it safely helps people with paroxysmal atrial fibrillation feel better after treatment.
-
Using CellFX technology to treat atrial fibrillation during cardiac surgery
This study is testing a new technology during heart surgery to see if it can safely help people with atrial fibrillation by creating a barrier around their pulmonary veins.
