(A) CAG image dotted line indicates the ectasic segment, portions ‘a’ to ‘c’ correspond to distal from CAE, CAE segment, and proximal from CAE respectively; (B) descriptions of CAE vessel anatomy using OCT; (C) description of CAE using IVUS; (D) the coronary flow patterns using Doppler velocimetry in each segment, all 12 month after the initial event with administration of anticoagulant agent. CAE – coronary artery ectasia; CAG – coronary angiography; IVUS – intravascular ultrasound; OCT – optimal coherence tomography.
