Indications for the transseptal approach to the left side of the heart have recently broadened, as it provides a therapeutic access for both left‐sided catheter ablation and also percutaneous transvenous valvular intervention. Despite rising demand for transseptal procedures, the technique and device used for this purpose have remained essentially unchanged over the past 4 decades. The possibilities of failure of puncturing distorted and thickened atrial septal tissue or risks of complications related to cardiac perforation remain limitations of the technique. A new radiofrequency catheter provides an alternative approach to create a controlled transseptal perforation. We applied this technique to a series of patients and evaluated its feasibility as an alternative to conventional transseptal needle puncture.
