Comparison of safety and efficacy of two different transseptal puncture devices
Study led by Dr. Bradley Knight, 2023: Comparison of transseptal puncture using a dedicated RF wire versus a mechanical needle with and without electrification in an animal model1
Key takeaways
Transseptal puncture with the VersaCross™ RF Transseptal Solution, compared to a mechanical needle with and without electrification:*
Achieved 100% transseptal puncture (TSP) success with fewer attempts (1.0 ± 0.0)
Required less power (approximately 10 W) to achieve TSP
Reported zero incidence of tissue coring
Introduction to devices for transseptal catheterization
Bradley Knight, MD, describes the benefits of using purpose-built radiofrequency (RF) technology for TSP compared to a standard or electrified mechanical needle, including less time to cross, lower complication rate and increased success rate.
Transseptal workflow with the VersaCross Access Solution
Bradley Knight, MD, explains the advantages of using the purpose-built 3-in-1 RF wire with the VersaCross Access Solution for transseptal catheterization, including elimination of exchanges.
Transseptal workflow with the AcQCross™ Transseptal Access System†
Bradley Knight, MD, summarizes the AcQCross Transseptal Access System† transseptal workflow and risks that may be associated with electrified mechanical needles, including tissue coring.
Study results: Comparing the safety and efficacy of two TSP devices
