The transseptal puncture (TP) technique was introduced into clinical practice during the late 1950s by Ross et al as a diagnostic tool to properly select patients for cardiac valve surgery.1,2 Over the years, its use for diagnostic purposes has declined, but a number of new interventional procedures utilizing TP have been developed. Currently, the most common indications are left heart electrophysiology ablations, percutaneous mitral valve repair/implantation, patent foramen ovale closure, left atrial appendage occlusion, paraprosthetic valve leak repair, and left ventricular assist device positioning.

The increasing number of interventional procedures as well as the use of large-bore sheaths and complex devices have led to improvements in technique and equipment. However, TP is still technically challenging, and some complications may occur. Consequently, special training is required, and only expert ...
