Key result
Multimodal imaging identifies rare congenital absence of the left atrial appendage during AF ablation.
Why the study?
Congenital absence of the left atrial appendage is an extremely rare anatomical variation with clinical significance in patients undergoing AF ablation.
Case Report (n=1)
Congenital absence of the LAA is a rare anatomical variation that can be identified pre-procedurally using TEE and CT.

Multimodality imaging can identify congenital LAA absence before AF ablation; leaves open its prevalence and procedural implications.
Congenital absence of the left atrial appendage (LAA) is extremely rare.We describe a case of congenial absence of the LAA in a patient scheduled for atrial fibrillation (AF) ablation. Absence of the LAA was found pre-procedurally by transoesophageal echocardiography (TEE) and cardiac computer tomography (CT). During the ablation procedure, the absence was confirmed by contrast injection at the usual location of the LAA.

Zhang et al. (2013) conducted a case report in Atrial fibrillation (n=1). Transoesophageal echocardiography and cardiac computer tomography was evaluated on Congenital absence of the left atrial appendage. Congenital absence of the left atrial appendage was identified pre-procedurally by TEE and CT and confirmed by contrast injection during an atrial fibrillation ablation procedure.
