  • Research summary

    Atrial fibrillation (AF) is the most common clinical cardiac rhythm disturbance affecting 1 in 200 people regardless of age. At present, standard care involves a procedure called an ablation. Small burn marks are made inside
    the heart in an attempt to correct the irregular heart beat. The main goal of AF ablation is isolating the electrical signals from the pulmonary veins that enter the left upper heart chamber (atrium). Delivering this energy with balloon catheters have demonstrated a shorter learning curve and reduced procedural time. The new multi pole ablation balloon (Heliostar) has demonstrated to be a safe and effective tool for AF abation. The posterior wall of the left atrium is adjacent to the oesophagus and a rare and severe complication is a connection between both structures (fistula). Bylimiting energy to the posterior wall and hence to the oesophagus there should be a reduced chance of fistula formation. This study will assess a new reduced energy delivery time, to the posterior wall, to achieve pulmonary vein isolation and assess safety by monitoring for any oesophageal injury through temperature monitoring and a post procedural gastroscopy.
