In a recent Cardiology article, John Lisko, MD, MPH, explains how the fundamental goal of transcatheter electrosurgery is to move conventional surgical techniques to the tip of a long guidewire.

He notes that to date, the technique has been applied to traversal from the vena-cava to the aorta (transcaval) for large bore access; laceration of the anterior mitral leaflet prior to transcatheter mitral valve implantation to mitigate the risk of left ventricular outflow tract obstruction; laceration of aortic scallops to prevent coronary obstruction (BASILICA); laceration of surgical and transcatheter mitral repairs (ELASTIC/ELASTA-Clip); traversing cardiac chambers, and traversing occluded arteries and veins.
