Transseptal Puncture

First published: 06 May 2022

Summary

Transseptal catheterization (TS) is an essential procedural skill required in the current era. The role of TS is increasingly gaining importance in the field of structural heart disease interventions. Isolated fluoroscopy-guided technique was initially used. In the current era, most of the centers have changed to utilization of transthoracic echocardiogram/intra-cardiac echocardiogram along with fluoroscopy to improve the safety of the procedure. Newer radio-frequency based puncture system has been shown to improve safety. Ideal puncture sites differ among different procedures involving left heart chambers. In this chapter, we discussed the embryology of interatrial septum, ideal puncture sites for different procedures, different types of equipment used to TS puncture including TS puncture needles, wires, bail-outs in case of resistant septum, complications of TS procedure and their management.
