ABSTRACT

Transseptal puncture (TP) is the procedure of accessing the left atrium (LA) by puncturing the interatrial septum (IAS) using a needle and specialized catheters. The LA is the most challenging heart chamber to enter percutaneously; it is attainable through the left ventricle and the mitral valve, but this approach requires two consecutive 180-degree catheter turns, which a 180-degree catheter turns, which can be technically demanding. TP allows direct access to the LA through the intra-atrial septum and systemic venous system. For these reasons, transseptal puncture is a special procedure that has serious complications and requires experience and has become popular again in recent years due to the increase in ablation procedures.
