Does cardiac computed tomography angiography improve device surveillance and assessment of peri-device leak compared to transoesophageal echocardiography in patients post left atrial appendage closure?
CCTA is a suitable and more sensitive alternative to TEE for device surveillance and assessing peri-device leak after left atrial appendage closure.
CCTA is a suitable alternative to TEE for device surveillance post LAAC. CCTA was more sensitive than TEE for assessing PDL and can delineate the cause of residual LAA contrast patency.
