What describes the 'chicken wing' LAA shape?

The 'chicken wing' shape of the Left Atrial Appendage (LAA) is characterized by its resemblance to the wings of a bird. This specific morphology features a broad base that tapers into a narrower tip, resembling the angle and shape of a wing. The design is pivotal because this configuration can influence the management of thrombus formation and subsequent interventions, such as LAA occlusion procedures. Understanding the anatomical variations of the LAA, including the 'chicken wing' shape, helps clinicians predict the challenges and tailor strategies for successful LAAO, thus enhancing patient safety and outcomes. The other descriptions do not accurately capture the unique wing-like appearance characteristic of the 'chicken wing' shape, which is essential in both anatomical studies and procedural planning.
