Background
High power short duration (HPSD) radiofrequency-ablation (RFA) is highly
efficient and safe while reducing procedure and RF time in pulmonary
vein isolation (PVI). The QDot-catheter is a novel contact-force
ablation catheter that allows automated flow and power adjustments
depending on the local tissue temperature to maintain a target
temperature during 90watts/4seconds lesions. We analysed intraprocedural
data and periprocedural safety using the QDot-catheter in patients
undergoing PVI for paroxysmal atrial fibrillation (PAF).
