Angiographic and IVUS features of coronary artery dissection.

	Angiography	IVUS
Dissection with intimal tear	radiolucent intimal flap delayed contrast clearance from false lumen	confirmation of true and false lumina identification of intimal tear length and morphology
Dissection without intimal tear (intramural hematoma)	narrowed vessel smooth stenosis	confirmation of intramural hematoma length and morphology
