ABSTRACT
Background: Rapid ventricular pacing is often required during transcatheter aortic valve replacement (TAVR) procedures. Pacing via the retrograde left ventricular guidewire (LV-GW) is an alternative strategy to conventional pacing using a right ventricular temporary pacing wire (RV-TPW). We report our single center experience with this strategy.
Methods: Two-hundred twenty-six patients who underwent transfemoral TAVR using pacing via LV-GW were included in this retrospective observational study.
Results: LV-GW pacing was successful in 224 (99%) of the cases. In two (1%) patients, a RV-TPW was inserted after attempted LV-GW pacing because of stimulation failure (n = 1) or instability (n = 1). Procedural TAVR success was obtained in 94.7% of the cases. Procedural complication rate was low and included 2.7% vascular complications, 0.9% unsuccessful valve deployment and 3.1% in-hospital death. Pericardial effusion requiring intervention occurred in three (1.3%) cases and was related to LV perforation (0.9%) and annular rupture (0.4%). As expected, no case of RV perforation was observed.
Conclusions: Pacing using LV-GW is a valuable alternative to RV-TPW for TAVR procedures. This avoids the need for an RV-TPW placement and reduces the risk of cardiac tamponade from RV perforation.
