Risks and benefits of an open irrigation tip catheter in intensive radiofrequency catheter ablation in patients with non-paroxysmal atrial fibrillation.


BACKGROUND Although open irrigation tip catheters (OITC) are effective in producing transmural radiofrequency (RF) lesions, they have the potential for fluid overload or excessive tissue damage. METHODS AND RESULTS The 203 patients with non-paroxysmal atrial fibrillation (NPAF; 85.2% males, 55.2+/-10.6 years old) who underwent RF catheter ablation (RFCA… (More)
