Comparison of Transseptal Puncture Techniques in Animal Model

This study evaluates the safety and efficacy of two transseptal puncture systems: the VersaCross™ RF Transseptal Solution and the FlexCath Cross™ Transseptal Solution. Using in vivo and ex vivo experiments on swine, the research highlights the advantages of RF technology, achieving 100% puncture success with lower power and fewer attempts compared to the mechanical needle, which was associated with higher tissue damage and coring incidents. Key findings support the use of purpose-built RF device
