Comparison of limits and advantages of CCT vs. TEE for preprocedural planning of LAAO.

	TEE	CCT
ADVANTAGES
	Standard of care in many centers	Higher spatial resolution
	No contrast medium	Low inter-observer variation
	No radiations	Optimal transeptal puncture planning
	Lower cost	Implant view planning
	Easily available	Potential for simulation/modeling
LIMITS
	Invasive	Contrast medium use
	Gastro-esophageal contraindications	Radiations
	Not optimal imaging in some cases	Higher cost

CCT: cardiac computed tomography; LAAO: left atrial appendage occlusion; TEE: transesophageal echocardiography.
