What You Need to Know Before You Apply

What is the purpose of this trial?

This trial evaluates the long-term safety and effectiveness of a new system called QDOT MICRO, combined with another tool, to treat individuals with paroxysmal atrial fibrillation (PAF). It targets those who continue to experience symptoms despite medication and may consider ablation to manage their condition. The trial suits individuals who have not undergone ablation before and are prepared to participate for the study's entire duration. As a Phase 3 trial, it represents the final step before FDA approval, offering participants the opportunity to contribute to the potential availability of a new treatment option.

What is the safety track record for the QDOT MICRO System for Atrial Fibrillation?

In a previous study, the QDOT MICRO System demonstrated promising safety results for treating atrial fibrillation (AFib). This system delivers energy to the heart to correct irregular heartbeats. Research has shown that patients generally tolerate the system well. Side effects were usually mild, including temporary discomfort at the procedure site. Another study found that most patients did not experience serious complications within a year after treatment. The FDA has approved the QDOT MICRO System for treating AFib, indicating it meets safety standards for this condition.12345

Why are researchers excited about this trial?

The QDOT MICRO System, when used with the VISITAG SURPOINT Module, is unique because it aims to offer a more precise and efficient approach to treating symptomatic drug-refractory paroxysmal atrial fibrillation (AFib). Unlike traditional catheter ablation techniques, which can be time-consuming and require multiple sessions, this system uses advanced technology to enhance the precision and speed of the procedure. Researchers are excited about this treatment because it has the potential to improve patient outcomes by reducing the overall procedure time and increasing the accuracy of lesion creation, which could lead to better long-term success rates in managing AFib.

What evidence suggests that the QDOT MICRO System is effective for atrial fibrillation?

Research has shown that the QDOT MICRO System effectively treats atrial fibrillation (AFib). In one study, 99% of patients achieved better control of their AFib, and 93.1% experienced symptom relief within a year. Another study found that 82.1% of patients did not experience a return of AFib after 12 months. These results suggest that the QDOT MICRO System significantly helps manage AFib symptoms and reduces episodes over time.14678
