First-In-Man Fully Leadless Transvenous Crt-P With A Transseptal Implant Of Wise-Crt System And Micra Pm

We describe the world's first fully leadless cardiac resynchronization therapy pacing implant with transseptal approach, in a patient with pacemaker dependency, atrial fibrillation, ischemic hypokinetic cardiomyopathy, and a history of pocket infections. After lead extraction, we implanted a MicraTranscathether Pacing System (R) (Medtronic, Minneapolis, MN, USA) as the sole right ventricular pacemaker, and the WISECRT system (EBR Systems, Sunnyvale, CA, USA) to provide biventricular pacing. We performed the WISECRT implant procedure using the transseptal approach given the presence of a prosthetic aortic mechanical valve, achieving satisfactory periprocedural results.
