Key result
Fusion imaging of transesophageal echocardiography and X-ray during left atrial appendage closure significantly reduced mean procedure time by 15 minutes (p<0.001) and contrast medium use compared to standard imaging.
Why the study?
LAAC is primarily guided by separate TEE and fluoroscopy, but whether fusion imaging of TEE and X-ray is feasible and improves procedural results remained to be determined.
Does fusion imaging of transesophageal echocardiography and X-ray improve procedural metrics (procedure time, contrast medium use) in patients undergoing left atrial appendage closure?

Mean Difference: -15
Absolute Event Rate: 30.2% vs 45.2%
p-value: p=<0.001
The use of fusion imaging combining transesophageal echocardiography and fluoroscopy during left atrial appendage closure significantly reduces procedure time and contrast medium volume without compromising safety.

May shorten LAA closure procedures; hypothesis-generating and requires randomized confirmation before practice change.
Ebelt et al. (2020) conducted a cohort in Atrial fibrillation (n=75). Fusion imaging of transesophageal echocardiography and X-ray vs. Standard imaging (separate TEE and fluoroscopy) was evaluated on Procedure time (MD -15 min, p=<0.001). Fusion imaging of transesophageal echocardiography and X-ray during left atrial appendage closure significantly reduced mean procedure time by 15 minutes (p<0.001) and contrast medium use compared to standard imaging.
