Chronic Total Occlusion of Coronary Artery
Early and Midterm Outcomes of Intravascular Ultrasound (IVUS) Versus Non-IVUS Guidance in Complex Coronary Chronic Total Occlusion (CTO) Revascularization.
Various CTO percutaneous coronary intervention (PCI) studies defined CTO as as a substantial atherosclerotic blockage with >3 months duration of TIMI (Thrombolysis in Myocardial Infarction) 0 flow other than via collaterals.

Aortic Dissection, Perfusion; Complications
Intravascular Ultrasound for the Evaluation of Malperfusion Syndrome in the Setting of Acute Aortic Dissection
