Comparison of Cooled‐Tip Versus 4‐mm‐Tip Catheter in the Efficacy of Acute Ablative Tissue Injury During Circumferential Pulmonary Vein Isolation

Abstract

Cooled-tip catheter has a superior long-term outcome than the 4-mm-tip catheter in CPVI, which may be associated with the efficacy of transmural block and electrical isolation in PV antrum.
