Comparison of effectiveness of an 8-mm versus a 4-mm tip electrode catheter for radiofrequency ablation of typical atrial flutter

Am J Cardiol. 2000 Nov 1;86(9):1029-32, A10. doi: 10.1016/s0002-9149(00)01145-0.

Abstract

An 8-mm catheter does not appear superior to 4-mm tip electrode for atrial flutter ablation. The potential advantage of allowing higher energy delivery on a larger surface is compensated by the lack of consistent contact with the endocardial surface.
