Objective To obtain unique images of left‐sided pacing lead implantations for the educational benefits of both physicians and medical device design engineers. Methods We employed Visible Heart® methodologies to obtain simultaneous videoscopic (internal and external) and flouroscopic footage of the device‐tissue interfaces during left‐sided pacing lead (Medtronic 4196 4F dual electrode lead) implantations within reanimated swine hearts. We targeted the lateral cardiac veins via delivery through the coronary sinus. We used an isolated cardiopleged heart from Yorkshire‐cross swines; the University of Minnesota's Animal Care and Use Committee approved all experimental protocols involved in this study. Results Figure 1 displays typical images obtained during the implantation of left‐sided leads: (1) fluoroscopic and videoscopic images of the initial cannulation of the coronary sinus; (2) fluoroscopic and fiberscopic images of the subselection of a target lateral vein; and (3) fluoroscopic, videoscopic, fiberscopic, and external images of a subsequently implanted left‐sided lead. Conclusion Using Visible Heart ® methodologies, we were able to obtain novel footage of left‐sided lead implantations that are of educational value for students, patients, physicians, and left‐sided lead device design engineers.
