Summary

This trial aims to show that the Biosense Webster ablation system is safe and effective in treating patients with paroxysmal atrial fibrillation by isolating the pulmonary veins.

Who is the study for?
This trial is for individuals with paroxysmal atrial fibrillation (PAF), which is an irregular heartbeat that disrupts normal blood flow. Participants must have symptoms that haven't improved with medication. Specific eligibility details are not provided, but typically participants should be adults in stable health condition.
What is being tested?
The study tests the safety and effectiveness of a new ablation system called THERMOCOOL SMARTTOUCH SF catheter paired with the TRUPULSE generator. This system aims to isolate atrial pulmonary veins to help control irregular heartbeats in PAF patients.
What are the potential side effects?
While specific side effects are not listed, typical ones from catheter ablation can include discomfort at the site of insertion, bleeding or bruising, heart rhythm problems, and rarely more serious complications like stroke or heart damage.
