  Figure 2. Transesophageal echocardiography for sizing of intravascular LAAO devices. Examples of different LAA measurements on a 90° TEE view. Solid and dashed lines represent LAA landing zone and depth, respectively; grey solid line represents the anatomical ostium while the red dashed circle is the left circumflex coronary artery.

  Figure 3. Importance of a low mid-to-anterior transseptal puncture. For LAAO the transseptal puncture should be low, in the mid to anterior septum to facilitate engagement of the LAA. On ICE (rightmost), the LAA and MV should be in view.
