Usefulness of Cutting Balloon Angioplasty Prior to Stenting with Intravascular Ultrasound Imaging Guidance for Spontaneous Multi-vessel Coronary Artery Dissection Including the Left Main Coronary Artery

We report a case of percutaneous coronary intervention for spontaneous multi-vessel coronary artery dissection including the left main coronary artery. This case suggests that intracoronary imaging is useful for understanding the complex anatomy and for choosing the appropriate management for effective revascularization. Furthermore, cutting balloon angioplasty prior to stenting is useful for preventing the longitudinal extension of the intramural hematoma and avoiding unnecessary stent implantation.
