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 ...
