Re: [echocardiography] Left Atrial Appendage Flow Patterns
to Daniel Sindler
The wave morphology from LAA that you present is normal
The main point is that regardles how many flow waves you may count
the first pair of flow reflections that follow the P wave should be of high velocity and high integral (planimetry).If either positive (filling) or negative (emptying) Vmax is <40cm/s and Int is <2cm then
you should consider your patient as possible LAA cardioembolic case.
