OBJECTIVES

The aim of this study was to evaluate the impact of echocardiographic guidance on the safety and efficacy of left atrial appendage closure (LAAC).

BACKGROUND

Expert consensus documents recommend intraprocedural imaging by means of either transesophageal echocardiography or intracardiac echocardiography to guide LAAC. However, no evidence exists that intraprocedural echocardiographic guidance in addition to fluoroscopy improves the safety and efficacy of LAAC.

METHODS

Consecutive LAAC procedures performed at a high-volume center between January 2009 and October 2020 were stratified on the basis of intraprocedural imaging modalities, including fluoroscopic guidance (FG) only or intraprocedural echocardiographic guidance (EG) in addition to fluoroscopy. The primary safety endpoint was the composite of procedure-related complications occurring within 7 days after the procedure. Technical success at 7 days and at follow-up were secondary endpoints.

RESULTS

Among 811 LAAC procedures, 549 (67.7%) and 262 (32.3%) were assigned to the FG and EG groups, respectively. After adjusting for confounders, EG remained associated with a lower rate of the primary safety endpoint (3.4% vs 9.1%; P = 0.004; adjusted odds ratio [OR]: 0.31; 95% CI: 0.11-0.90; P = 0.030). Technical success trended higher at 7 days (92.1% vs 87.2%; P = 0.065; adjusted OR: 1.68; 95% CI: 0.95-3.01; P = 0.079) and was significantly improved with EG compared with FG (87.6% vs 79.9%; P = 0.018; OR: 4.06; 95% CI: 1.60-10.27; P = 0.003) after a median follow-up period of 4.9 months (interquartile range: 3.4 months-6.2 months).

CONCLUSIONS

In a large cohort of consecutive LAACs, the use of intraprocedural echocardiography to guide intervention in addition to standard fluoroscopy was associated with lower risks for procedural complications and higher mid-term technical success rates.
