Spontaneous echo contrast is also associated with which of the following?

• A. Embolic complications
• B. Decreased LV function
• C. Increased LV preload
• D. No relation to embolism

Answer: (A)

Spontaneous echo contrast shows slow, swirling blood flow and red blood cell aggregation in a chamber, which is a sign of blood stasis and a pro-thrombotic environment. When flow is this sluggish, thrombus can form even if one isn’t yet seen, and those clots can break off and travel to the systemic circulation. That makes embolic complications the most clinically important association of this finding. While poor LV function can contribute to the low-flow state that produces spontaneous echo contrast, the key point is the heightened risk of thrombus formation and embolization. Increased LV preload isn’t a defining link to this phenomenon, and saying there’s no relation to embolism would be inaccurate.
