Temporary wire pacing (TWP) involving a separate right ventricular (RV) pacing electrode during balloon aortic valvuloplasty (BAV) and transcatheter aortic valve replacement (TAVR), is effective for both BAV and TAVR stability during deployment. Hilling-Smith et al. describe their experience on 208 TAVR and BAV patients using the left ventricular (LV) support guidewire instead of the separate RV pacing electrode. The need for intraprocedural TWP during TAVR occurred in 5% of patients with the LV support guidewire, with an overall 21% need of PPM during the index hospitalization. No events were demonstrated during BAV procedures. LV pacing with the support guidewire is feasible. The intraprocedural need for pacing and a 48-hr observation period probably limit its use in TAVR. In BAV it can be considered as an alternative pacing strategy.
