BACKGROUND: The optimal imaging modality for guiding left atrial appendage occlusion remains unclear.
OBJECTIVES: The authors compared the effectiveness and safety of intracardiac echocardiography (ICE) vs transesophageal echocardiography (TEE) during left atrial appendage occlusion.
METHODS: Electronic databases were searched through November 2025 for studies that compared procedural success and safety with ICE vs TEE. We pooled data using a random-effects model to calculate ORs for categorical outcomes and mean differences (MDs) for continuous variables. A subgroup analysis was performed for unadjusted and adjusted data.
RESULTS: The meta-analysis included 27 observational studies, of which 9 studies reported adjusted summary estimates. Procedural success was comparable in both groups (unadjusted OR: 1.16; 95% CI: 0.92-1.45, I2 = 0%; adjusted OR: 1.40; 95% CI: 0.99-1.98, I2 = NA). ICE was associated with significantly shorter procedure duration in the adjusted analyses (MD -20.76 minutes; 95% CI: -26.99 to -14.53, I2 = 0%), though no difference was observed in unadjusted analyses (MD -0.13; 95% CI: -5.40 to 5.14, I2 = 95%). ICE was associated with a higher incidence of in-hospital pericardial effusion requiring intervention (unadjusted OR: 1.52; 95% CI: 1.13-2.04, I2 = 9%; adjusted OR: 1.74; 95% CI: 1.15-2.64, I2 = 8%). ICE was associated with a higher incidence of residual iatrogenic atrial septal defect at <4 months (unadjusted OR: 1.61; 95% CI: 1.20-2.16, I2 = 0%).
CONCLUSIONS: ICE and TEE demonstrated comparable procedural success. However, ICE was associated with shorter procedural duration at the expense of a higher incidence of intervention-requiring pericardial effusion and residual iatrogenic atrial septal defect.
