Diastolic flow reversal in the descending aorta:


Pitfalls in aortic leaflet coaptation.

Excerpt from the International Echocardiography Discussion List:
The M-mode shows that the middle echo of the closed aortic valve is not a single or nearly single line but shows two centered separate lines. This would suggest wide open aortic regurgitation. However, one must be careful with such a diagnosis since angulation of the M-mode beam plays a role as well as the location i.e. where the commisures of a malformed valve are cut. To read severity of valvular disease from this M-mode picture alone cannot be recommended. The 2D echo below is from the same patient and shows the diastolic aortic leaflet separation.
