Direct Rapid Left Ventricular Wire Pacing during Balloon Aortic Valvuloplasty
Key result
Direct left ventricular guidewire pacing during balloon aortic valvuloplasty was associated with lower in-hospital mortality compared to temporary right ventricular pacing (2.0% vs. 9.8%, p=0.01).
Why the study?
Rapid ventricular pacing is mandatory for balloon positioning during BAV, but the safety and efficacy of direct LV guidewire pacing compared to standard RV temporary pacemaker pacing needed assessment.
Does direct rapid left ventricular guidewire pacing improve safety and procedural efficiency compared to temporary right ventricular pacemaker placement in patients undergoing balloon aortic valvuloplasty?
