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.
