Key result
Applying brief pulses of radiofrequency energy from a standard electrosurgical cautery generator through the needle tip facilitates transseptal puncture.
Why the study?
Does applying brief pulses of radiofrequency energy through the needle tip facilitate transseptal puncture?
Does applying brief pulses of radiofrequency energy through the needle tip facilitate transseptal puncture?
Applying radiofrequency energy through a standard transseptal needle may facilitate puncture in challenging interatrial septal anatomies.

May aid transseptal access in difficult septa; leaves open need for randomized comparison before practice change.
Transseptal puncture is a standard means of catheter access to the left atrium via the venous system, but carries a risk of cardiac perforation. Stretching and increased force to traverse the septum are required with elastic, aneurysmal, or thickened interatrial tissue. We describe a technique that facilitates transseptal puncture by applying brief pulses of radiofrequency energy from a standard electrosurgical cautery generator through the needle tip.
