Leadless Pacemaker Implantation in a Patient With Previous Aortic, Mitral, and Tricuspid Valve Interventions
Case Presentation
J INVASIVE CARDIOL 2021;33(10):E841.
Key words: leadless pacemaker, prosthetic valve
An 81-year-old patient with previous transcatheter aortic valve replacement, transcatheter mitral valve repair, and conventional biological tricuspid valve replacement presented with symptomatic complete atrioventricular block. Pacemaker implantation was performed under mild sedation, through a 27 Fr outer-diameter right femoral venous sheath. Fluoroscopy-guided tricuspid valve crossing (Video 1) was performed using the Micra Transcatheter Pacing System (Medtronic) (Figures 1A, 1B), with a right ventricular septal positioning (Figures 1C). After device fixation and traction testing (Figures 1D), the tether was cut and the delivery system was removed (Figures 1E, 1F). Postoperative pacemaker parameters were good and the patient had no pathological tricuspid valve regurgitation.
