TMVR Procedural Efficiency With Use of Baylis Medical’s VersaCross RF Transseptal Solution Demonstrated in Study

December 1, 2020—Baylis Medical Company, Inc. announced the publication of findings from the initial clinical experience with the company’s VersaCross radiofrequency (RF) transseptal system for transcatheter mitral valve repair (TMVR) by Neila Sayah, MD, et al in Catheterization and Cardiovascular Interventions.

According to Baylis Medical, the study demonstrated procedural efficiency using the VersaCross for the MitraClip (Abbott) TMVR procedure. The investigators reported guide delivery from femoral access in < 7.5 minutes: 3.3 minutes to gain transseptal access plus 3.8 minutes to achieve MitraClip guide delivery. The procedural success rate was 100%.

The company stated that previously published data cited 16 minutes to gain transseptal access with the use of other transseptal solutions. Additionally, the investigators noted a reduced number of wire exchanges required, with the ability to reposition puncture location on the fossa ovalis without the need to rewire.

The investigators were led by Anita W. Asgar, MD, an interventional cardiologist in the Cardiology Division of the Montreal Heart Institute in Montreal, Quebec.

“The VersaCross platform has improved efficiency in my practice,” commented Dr. Asgar in the company’s press release. “The exchangeless technology allows me to perform precise puncture and delivery of MitraClip guide in under 8 minutes, allowing for safer, more efficient, and predictable procedures for my patients.”


Baylis Medical advised that the VersaCross solution features a single RF-tipped wire that is used to introduce the transseptal sheath into the superior vena cava, gain transseptal access, and act as an exchange wire in the left atrium to facilitate MitraClip guide delivery. The VersaCross platform provides an exchangeless solution for access-to-delivery of left heart therapy devices, which typically involves exchanging multiple devices to achieve and maintain transseptal access. The VersaCross solution can be customized to include J-tip and pigtail wire configurations as well as tailor-built fixed and steerable sheath options.
