What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to Achieve First Transseptal Puncture
Time Frame: 0-30 minutes (from insertion of guidewire to removal of guidewire of first transseptal)
|
First transseptal time was recorded for each participant, starting with insertion of the long guidewire into the femoral short sheath (J wire for RF needle group, VersaCross wire for RF wire group) and stopping once the transseptal sheath was positioned in the LA and the dilator and guidewire were fully removed from the long sheath.
Median time in minutes to completion of the first transseptal puncture during the cardiac ablation procedure between the RF needle and RF Wire group was compared as the outcome.
|
0-30 minutes (from insertion of guidewire to removal of guidewire of first transseptal)
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to Achieve Second Transseptal Puncture
Time Frame: 0-30 minutes (from insertion of guidewire to removal of guidewire of second transseptal)
|
Second transseptal time was recorded for each participant, starting with insertion of the long guidewire into the femoral short sheath (J wire for RF needle group, VersaCross wire for RF wire group) and stopping once the transseptal sheath was positioned in the LA and the dilator and guidewire were fully removed from the long sheath.
The median time in minutes to completion of the second transseptal puncture during the cardiac ablation procedure between the RF needle and RF Wire group was compared as a secondary outcome.
Participants that did not undergo 2 transseptal punctures were not included in this analysis.
|
0-30 minutes (from insertion of guidewire to removal of guidewire of second transseptal)
|
Combined Transseptal Time
Time Frame: 0-60 minutes (summation of first transseptal and second transseptal times)
|
Combined transseptal time was calculated for each participant by summing up participants' first and second transseptal times.
The median combined transseptal time in minutes between the RF needle and RF Wire group was compared as a secondary outcome.
Participants that did not undergo two transseptal punctures were not included in this analysis.
|
0-60 minutes (summation of first transseptal and second transseptal times)
|
Fluoroscopy Time
Time Frame: 0-60 minutes (from insertion of guidewire to removal of guidewire of first transseptal and second transseptal)
|
Fluoroscopy time (amount of time operators used fluoroscopy during a transseptal puncture) was recorded for each participant, starting with insertion of the long guidewire into the femoral short sheath (J wire for RF needle group, VersaCross wire for RF wire group) and stopping once the transseptal sheath was positioned in the LA and the dilator and guidewire were fully removed from the long sheath.
Median fluoroscopy time during the first and second transseptal punctures between the RF needle and RF Wire group was compared as a secondary outcome.
|
0-60 minutes (from insertion of guidewire to removal of guidewire of first transseptal and second transseptal)
|
Number of Participants With Equipment Exchanges
Time Frame: (0-8 hours) duration of cardiac ablation procedure
|
An equipment exchange was defined as the removal of the J or RF wire from the dilator and sheath assembly before transseptal puncture; all RF needle punctures required at least 1 equipment exchange, although further exchanges could be performed as necessary if the initial pull-down resulted in inadequate positioning of the sheath and dilator and readvancement of the transseptal assembly into the SVC was necessary. The number of equipment exchanges during the cardiac ablation procedure between the RF need and RF wire groups were compared. |
(0-8 hours) duration of cardiac ablation procedure
|
Complication Rates
Time Frame: complications were assessed during the duration of cardiac ablation procedure (up to 8 hours)
|
The number of participants with complications during the procedure between the RF needle and RF wire groups was compared as a secondary outcome.
|
complications were assessed during the duration of cardiac ablation procedure (up to 8 hours)
