Steerable versus non-steerable sheaths during pulmonary vein isolation: impact of left atrial enlargement on the catheter-tissue contact force

摘要

Purpose The influence of left atrial (LA) enlargement on the efficacy of steerable sheath usage during pulmonary vein (PV) isolation is poorly understood. Here, we compared the catheter-tissue contact force (CF) and clinical outcomes between steerable and non-steerable sheaths among patients with different severities of LA enlargement.
