↵a Procedures using LAA occlusion devices are typically performed either by electrophysiologists, interventional cardiologists (adult or pediatric), or cardiovascular surgeons. This document uses the term “procedural specialist” to apply to members of any subspecialty who implant LAA occlusion devices. In some cases, a physician team will be composed of two operators; therefore, the procedural volume criteria and ongoing proficiency requirements apply to at least one member of the team.
↵b LAA occlusion involving a transseptal catheterization that is primary (i.e., WATCHMAN or similar devices) or adjunctive to a percutaneous pericardial approach (i.e., LARIAT), percutaneous left ventricular assist device placement when such devices involve transseptal approach (i.e., Tandem Heart), endovascular catheter ablation within the left side of the heart, pulmonary vein stenting, balloon mitral valvuloplasty, percutaneous closure of prosthetic mitral paravalvular leaks using a transseptal approach, antegrade balloon aortic valvuloplasty, mitral valve repair using the MitraClip system or other technique involving transseptal puncture, ASD or PFO closure, and diagnostic transseptal catheterization.
