Dynamic aortic obstruction from type B aortic dissection
Dynamic aortic obstruction from type B aortic dissection
This dynamic magnetic resonance angiogram demonstrates the mobility of the aortic dissection flap throughout the cardiac cycle. During systole, the dissection flap moves into the aortic lumen, which can compromise the renal and visceral artery takeoffs as the dissection flap distally moves and covers their origins.
