Debate: Intravascular imaging in the treatment of complex lesions. Rationale for selective use

In which settings do you consider one imaging modality preferable to the other, and what are your own preferences in clinical practice?A: Overall, I use IVUS to treat left main coronary artery lesions and chronic total coronary occlusions; for other complex lesions, I rather use either IVUS or OCT.Furthermore, clinical factors such as renal impairment, which favors the use of IVUS, and anatomical factors such as tortuosity and calcification, should be considered because they may influence the ease with which one device or the other can be advanced.
