Hello everyone myself Dr Nagendra thalor.today in this video we will discuss about traffic jam sign in echocardiogrphy
It is multiple echogenic shadow seen moving to and fro in dilated Inferior vena cava and hepatic vein in case of constructive pericarditis
Also seen in case of grossly dilated ivc and hepatic vein in high right atrial pressure situation
It occurs due to low blood flow velocity which may lead clot formation and increased risk of thromboembolism
This sign reversed after pericardiotomy 
Thanks
