Best Practices in Left Ventricular Pacing for Transcatheter Aortic Valve Replacement

Transcatheter aortic valve replacement (TAVR) is continually evolving, with a recent emphasis on a "minimalist" approach toward reducing procedural invasiveness, duration, and recovery time. Whereas a better understanding of the relationship between TAVR and new conduction disturbances has led to improved periprocedural management, intraprocedural rapid-pacing techniques have not evolved beyond traditional right ventricular temporary pacing. An alternative strategy utilizing the left ventricular guidewire for rapid pacing has been developed with evidence supporting its safety, effectiveness, and potential reductions in procedure time and cost. This review will outline the current best practices in left ventricular pacing for TAVR, a practical technique that embraces the minimalist approach to TAVR and may be considered for routine use. It aims to explore the current evidence and combine this with expert opinion to offer a strategy for temporary pacing that encourages efficiencies for physicians and patients without compromising periprocedural safety.
