- W2885657046 abstract "Radiofrequency (RF) ablation is a highly successful procedure for the management of typical atrial flutter (AFL), an abnormal heart rhythm originating within the atria. There is no strong evidence that the use of contact force (CF) has any impact on procedural duration or acute success in the management of cavotricuspid isthmus (CTI)-dependent AFL. The aim of this study was to compare acute procedural parameters using a non-CF, 4-mm, gold-tip, irrigated catheter and a CF-sensing catheter in patients with AFL.This was a retrospective cohort study. Consecutive patients who underwent typical AFL catheter ablation with either a gold-tip or CF-sensing catheter were enrolled. The procedural parameters obtained were: time to achieve bidirectional block, time to terminate AFL, total duration of RF application, procedure duration, fluoroscopy time, acute reconnection within 20 minutes following the last RF application, and procedural complications.Of the 40 patients screened, 37 were included in the study. The procedural endpoint of bidirectional isthmus block was achieved in all patients. The use of gold-tip catheters was associated with a shorter length of time to achieve bidirectional block (median time: 20.0 minutes [interquartile range {IQR}: 12.0-28.0 minutes]) compared with a median time of 36.0 minutes (IQR: 12.0-53.0 minutes; p=0.048) in the CF group. Furthermore, there was a trend toward reduced procedural duration in favor of the gold-tip catheter (median goldtip: 74.0 minutes [IQR: 57.0-84.0 minutes]; median CF: 85.0 minutes [IQR: 57.0-107.0 minutes]; p=0.171). A greater requirement for the use of long sheaths was observed in cases where the CF catheter was employed for the procedure (CF: 11, 57.9 %; non-CF: 1, 5.6%; p=0.005).The time required to achieve bidirectional block, which is also reflected in the procedural time, was less when using a gold-tip catheter, and there was less need for the use of a long sheath. Further studies may be useful to evaluate this finding." @default.
