Expanding subintimal coronary dissection under a stent‐covered arterial segment: Serial intravascular ultrasound observations

A patient with an angiographically unrecognized minor coronary dissection in a stent‐covered coronary segment in which a type D spiral dissection extended submedially to the distal artery is described. This complication occurred 6 months after stent implantation and was ascribed to injury of the stented vessel wall during an intravascular ultrasound study. Cathet. Cardiovasc.
