Transseptal catheterization has become a routine part of left atrial interventional electrophysiologic procedures. Although commonly performed, this aspect of the procedure is not without risk. One of the possible complications includes perforation and cardiac tamponade which may require percutaneous drainage or even open surgical repair. Contemporary tools, such as intracardiac echocardiography and radiofrequency-assisted transseptal tools have reduced the risk of cardiac tamponade during transseptal catheterization.1 While such tools are widely available, these technologies can be cost-prohibitive for routine use.
