    Let us now move in to greater detail about mesenteric ischemia. This is acute mesenteric ischemia, an absolute emergency. The patient walks in or he get a clinical vignette and you've been given an ECG. On your ECG, take a look at your P waves or at least you try to identify them and you can?t. They are absent or they are wavelike. And you notice that the heart rate is approximate 250 bits per minute. Patient here maybe approximate 65 years of age, so elderly. At this point, you are worried about the left atrium undergoing atrial fibrillation and with this turbulence that's taking place within left atrium then this is part of Virchow's triad. Meaning to say, that it is now prone to thrombotic formation. A thrombosis that is now developing in the left atrium becomes very dangerous, because you are worried about breaking off the thrombi and embolization destroy. Now, I will tell you, that the embolization and the most important of embolization or the most destructive, but not the most common side of embolization. So, a couple of things here. When we talk about cerebrovascular accident and stroke, when you have embolization from atrial fibrillation of your thrombi from the left atrium, what you are worried about and why you are giving this patient prophylactic warfarin, is so that you will prevent out, to this day clinically it's been proven evidence based, that warfarin is the drug of choice to prevent cerebrovascular accidents as a result of embolization of a thrombus in left atrium secondary to atrial fibrillation. You got all that? Now, in terms of embolization, it is not the carotid artery in which it is the number one site. It may end up in the renal artery with embolization or as our topic here...
