Baseline angiographic images: (A) cranial angiographic view of left coronary artery system showing the chronic total occlusion (CTO) of anterior descending (LAD). The proximal tortuosity of LAD and spot calcifications (white arrows), which present just upstream to the emergence of a septal and a diagonal branch, did not allow the advancement of intravascular ultrasound probe in order to identify the CTO’s entry-point. (B) Cranial left anterior oblique view of right coronary angiography showing the faint contralateral collateralization for distal LAD (arrows).
