Description
M Asami and co-authors follow new wall motion problems spotted right after left bundle branch area pacing in a 2026 follow-up study. Of ninety-five patients in a row, forty had scans at three years and formed the study group. Five of them, about fourteen percent, showed fresh wall motion problems right after implant, mostly in the front septal wall the lead screws into. Ejection fraction barely moved across the group.
By year three a split appeared: patients with the early problem averaged an ejection fraction near fifty-two percent, below the roughly sixty-one percent of those without it. Pacing burden was nearly total in everyone, so exposure was equal. The authors read this as possible local muscle injury or uneven motion seeded at the lead site. They argue for ultrasound checks after this pacing style, rather than assuming a clean implant scan settles the question.
