An aortic dissection flap, in cardiac ultrasound, refers to the intimal tear separating true and false lumens within the aorta. This critical finding indicates an acute aortic dissection, a life-threatening condition requiring immediate medical attention. High-resolution cardiac ultrasound, particularly transesophageal echocardiography, is crucial for visualizing this mobile flap and assessing its extent, confirming the diagnosis, and guiding urgent management.
Identifying an aortic dissection flap on ultrasound helps clinicians quickly evaluate blood flow dynamics, identify any compromise to arterial branches, and determine the dissection’s classification. Early detection via focused cardiac ultrasound (POCUS) is vital for improving patient outcomes in this cardiovascular emergency, emphasizing the importance of precise imaging in cardiac medical diagnostics.
