Atraverse is creating the next generation transseptal access device for use in minimally invasive cardiac procedures requiring access to the left chamber of the heart. The company’s innovative HOTWIRE system, featuring universal sheath compatibility and optimized RF biophysics, aims to enhance outcomes and streamline workflows for physicians treating cardiovascular disease in millions of patients worldwide. The poster looks at monitoring RF biophysics and applying an automated energy cessation algorithm limits energy duration after a septal crossing and reduces the incidence of LA injury and inadvertent microembolic load.
