Is the Left Atrial Appendage (LAA) anatomical shape really meaningless measure for stroke risk assessment?

Since atrial fibrillation (AF) associated stroke is mostly originated from thrombogenesis in the left atrial appendage (LAA), it has been thought that the anatomical morphology of LAA would be an important contributing factor in the process of thrombogenesis [1]. However, recent studies remained controversies in terms of their association between stroke risk and LAA morphology [2 –4]. There are several reasons for these controversies. First, LAA morphology is so diverse that its classification into several pre-defined types (i.e.
