Two-dimensional echocardiographic recognition of an aortic intimai flap prolapsing into the left ventricular outflow tract

A 59 year old man presented with dyspnea and a new murmur of aortic regurgitation. Two-dimensional echocardiography demonstrated a to and fro motion of the intimai flap as it prolapsed into the left ventricle and was thrust into the aorta during diastole and systole, respectively. At surgery, the echocardiographic and angiographic findings were confirmed and a proximal aortic dissection was identified. Prolapse of an intimai flap from the aorta into the left ventricular outflow tract represents a new two-dimensional echocardiographic sign of aortic dissection
