VOLT CE Mark Study

The VOLT study is evaluating a new catheter ablation system designed to treat atrial fibrillation (AFib) — an irregular and often fast heartbeat — by electrically isolating the pulmonary veins (the most common trigger area for AFib). It is testing the safety and performance of this device as part of CE marking (European regulatory approval). **You may be eligible if...** - You are 18 or older with symptomatic atrial fibrillation (paroxysmal — episodes that stop on their own, or persistent — continuous but under 1 year) - Your AFib has been confirmed by ECG or heart monitor - You have tried and failed, cannot tolerate, or have contraindications to at least one antiarrhythmic medication - You are scheduled for a pulmonary vein isolation (catheter ablation) procedure **You may NOT be eligible if...** - You have had continuous AFib for more than 1 year - Your AFib is caused by a reversible problem (thyroid disease, alcohol, electrolyte imbalance) - There is a blood clot in your heart - Your left atrium (heart chamber) is very enlarged (≥ 5.5 cm) - Your heart pumping function is severely reduced (ejection fraction < 35%) - You have severe heart failure (NYHA class III or IV) - Your BMI is above 40 - You are pregnant Talk to your doctor to see if this trial is right for you.
