Does an optimized fluoroscopy protocol reduce radiation exposure in patients undergoing cryoballoon-based pulmonary vein isolation for atrial fibrillation?
Absolute Event Rate: 389% vs 2168%
p-value: p=< 0.0001
An optimized fluoroscopy protocol significantly reduces radiation exposure and fluoroscopy time during cryoballoon-based pulmonary vein isolation without compromising acute efficacy.
Reißmann et al. (2017) conducted a cohort in Symptomatic atrial fibrillation (n=120). Optimized fluoroscopy protocol vs. Conventional fluoroscopy settings was evaluated on Dose area product (p=< 0.0001). An optimized fluoroscopy protocol significantly reduced median dose area product compared to conventional settings (389 vs. 2168 cGycm2; P<0.0001) in cryoballoon-based pulmonary vein isolation.
