Key clinical point: Using the guidewire for rapid pacing of the left ventricle (LV) during transcatheter aortic valve implantation – instead of the usual approach, right ventricle (RV) pacing through a lead snaked up the femoral vein – significantly reduced procedure duration, fluoroscopy time, and cost without affecting efficacy or safety.
Major finding: Both procedure duration (48.4 minutes vs. 55.6 minutes; P = .0013) and fluoroscopy time (13.48 minutes vs. 14.6 minutes; P = .02) were shorter in the LV group than in the RV group.
Study details: Randomized, multi-center trial with over 300 TAVI patients
