Thee Evolving Role of Augmented Reality in Cardicac Device Surgery

Cardicac deviche surgery - concluassing thee implantation of pacemakers, implantable cardioverter- defibrylators (ICD), and cardicac resynchronization therapy (CRT) devices - demands exacting precision. Suboptimal lead placement can result in pacing failure, phrenic nerve stimulation, or asgreed risk of dislocation. For decades, fluoroscopic guidance has been the standard, but offers only a twoidimensional projection d expose bots both patient and operational tim tim tilotilotis.

Technical Foundations of AR in the Operating Room

Klinika Advantages Over Conventional Fluoroskopia

Te prymary beneficjant of AR- assisted nawigation lies in thee reduction of reliance on twoimentional fluoroscopic snapshots. In conventional pacing lead implantation, thee surgeon obtains multiple fluoroscopic views (typically posteroanterior and lateral) to gauge lead position relativa to landmarks like the right cameraar apex or thee coronary sinus.
