Absolute Event Rate: 48.5% vs 93.9%
p-value: p=0.01
Automated real-time integration of echocardiography and fluoroscopy during LAA closure significantly reduces radiation exposure and fluoroscopy time without increasing procedure time or complications.
No takes yet. Share an insight, caveat, or question.
May reduce radiation in LAA closure; hypothesis-generating and requires randomized confirmation before practice change.
Jungen et al. (2015) conducted an RCT in Nonvalvular atrial fibrillation requiring left atrial appendage closure (n=34). Integrated echocardiography and fluoroscopy imaging (EchoNavigator) guidance vs. Standard guidance without integrated imaging was evaluated on Total radiation dose (Gy/cm2) (p=0.01). Automated real-time integration of echocardiography and fluoroscopy imaging during left atrial appendage closure reduced total radiation dose by 52% compared to standard guidance.
