ClinConnect Summary

This clinical trial is studying a new device called the Affera SpherePVI™ Multi-Ablation System, which is designed to treat a heart condition known as paroxysmal atrial fibrillation (PAF). PAF causes the heart to beat irregularly and can lead to symptoms like palpitations or fatigue. The trial aims to evaluate how safe and effective this device is in helping patients who have not found relief with other medications.

To participate in this trial, you need to be between 18 and 75 years old and have a history of PAF confirmed by a doctor. You should have already tried at least one anti-arrhythmic medication without success. Participants will receive the treatment and will need to attend follow-up appointments to monitor their progress. It's important to note that certain health conditions may prevent you from joining, such as having ongoing heart issues or recent heart surgeries. If you're interested, discussing this trial with your doctor could be a great first step.
