Despite the advancement of various devices and techniques, percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) lesion remains one of the major challenges in interventional cardiology fields. It is also associated with higher complications than non-CTO-PCI due to procedural complexity. We presented a case of iatrogenic compressive coronary intramural hematoma (IMH) as CTO-PCI complications, which was judiciously detected and successfully managed with a cutting balloon.
Keywords: acute vessel closure; cutting balloon; grenadoplasty; iatrogenic coronary artery dissection; intravascular ultrasound (ivus).
