Key result
ICE enables safe, contrast-free Aveir VR leadless pacemaker implantation via real-time right ventricular assessment.
Intracardiac echocardiography can be used to safely guide leadless pacemaker implantation without contrast in patients with severe contrast allergy.
May support contrast-free leadless pacing in allergic patients; hypothesis-generating case report leaving generalizability open.
Intracardiac echocardiography (ICE) enabled safe, contrast-free implantation of an Aveir VR leadless pacemaker in a high-risk patient with severe contrast allergy and prior device infection, allowing real-time assessment of right ventricular anatomy and myocardial wall thickness to minimize perforation risk.
