Why the study?
Fast-track protocols aim to simplify TAVI, prompting the need to assess the safety and efficacy of temporary left ventricular guidewire pacing during valve deployment.
Does temporary left ventricular pacing using the valve delivery guidewire provide successful rapid pacing and comparable safety to transvenous right ventricular pacing in patients undergoing TAVI?
Population
307 consecutive patients undergoing TAVI with Edwards SAPIEN S3 or Medtronic Evolut Pro+
Comparison
Left ventricular guidewire pacing vs conventional previous right ventricular pacing cohort
Design
Prospective observational study

LV wire pacing may support TAVI pacing needs; leaves open randomized confirmation, especially with LVEF <52%.
Does temporary left ventricular pacing using the valve delivery guidewire provide successful rapid pacing and comparable safety to transvenous right ventricular pacing in patients undergoing TAVI?
Left ventricular wire pacing during TAVI is a safe and effective alternative to transvenous right ventricular pacing, though caution is needed in patients with reduced ejection fraction (<52%).
