“…When PCI is entertained or when diagnosis is unclear, intravascular imaging, if possible, can demonstrate intimal tears, IMHs, and areas compressed by the false lumen, as well as confirm the absence of atherosclerotic plaque in the intima of the true lumen to support a SCAD diagnosis. Due to higher resolution imaging, OCT is possibly a superior modality for SCAD delineation at the expense of increased dye use and lesser depth penetration than IVUS [3]. There is, however, an inherent risk of these diagnostic intravascular procedures (OCT and IVUS).…”
