Pacing during TAVR through a coronary wire in the coronary artery and left ventricular wire

Year: 2026

Type: article

Abstract: The conventional pacing-over-the-wire technique in transcatheter aortic valve replacement (TAVR) results in high impedance and voltage thresholds, which may cause loss of capture and valve embolisation. Our team reported that coronary wire pacing, in which a coronary wire is placed in the left coronary artery (anode) and a left ventricular wire (cathode), is associated with extremely low impedance and pacing voltage thresholds in patients who are at high risk of coronary obstruction. Moreover, coronary wire pacing is simple and reliable. In this study, we illustrate the coronary wire pacing technique in a patient to provide a new approach to wire pacing in TAVR.
