Abstract:
Objective To observe the value of transesophageal echocardiography(TEE)for guiding left atrial appendage closure(LAAC)with LAmbre occluder.Methods Data of 40 non-valvular atrial fibrillation(NVAF)patients who underwent LA AC with LAmbre occluder were retrospectively analyzed.CT angiography(CTA)before treatment,TEE and digital subtraction angiography(DSA)findings during LAAC were comparatively observed,and the correlations of the anchor area diameter and left atrial appendage opening diameter measured with the above three as well as occluder size were analyzed,and TEE and DSA for evaluating peri-device leak(PDL)were compared.Results LAAC were successfully performed with LAmbre occlude in all 40 cases.The diameter of the fixed umbrella was positively correlated with anchor area diameter measured with CTA,TEE and DSA(r=0.79,0.82,0.91,all P＜0.01),of occlusion umbrella was positively correlated with left atrial appendage opening diameter measured with CTA,TEE and DSA(r=0.56,0.89,0.86,all P＜0.01).Immediately after the release of occluder in LAAC,PDL occurred in 16 cases and were detected with both TEE and DSA,while in the rest 24 cases no PDL was found with neither TEE nor DSA.Conclusion TEE had comparable value to DSA for guiding LAAC using LAmbre occluder.
