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.
经房间隔途径进入心脏左侧的适应证最近有所拓宽，因为它为左侧导管消融和经皮经静脉瓣膜介入治疗都提供了一种治疗途径。尽管对经房间隔手术的需求不断增加，但在过去40年里，用于此目的的技术和设备基本保持不变。穿刺扭曲和增厚的房间隔组织失败的可能性或与心脏穿孔相关的并发症风险仍然是该技术的局限性。一种新型射频导管提供了一种制造可控房间隔穿孔的替代方法。我们将该技术应用于一系列患者，并评估了其作为传统房间隔穿刺针替代方法的可行性。
