Why the study?
Coronary artery dissection in the RCA ostium is a rare but fatal complication during PCI to RCA lesions, and stent implantation to the ostium may prevent it.
Does ostial stent coverage reduce ischaemia-driven target vessel revascularization in patients undergoing IVUS-guided PCI for severely narrowed non-ostial RCA lesions with mild to moderate ostial stenosis?
Does ostial stent coverage reduce ischaemia-driven target vessel revascularization in patients undergoing IVUS-guided PCI for severely narrowed non-ostial RCA lesions with mild to moderate ostial stenosis?
Continuous ostial plaque detected by IVUS is strongly associated with the decision to perform aorto-ostial stent coverage during PCI for non-ostial RCA lesions, which may trend toward reducing ischemia-driven TVR.

May inform ostial stent decisions in RCA PCI; leaves open need for prospective validation of associated factors.
INTRODUCTION: In percutaneous coronary intervention (PCI) to atherosclerotic lesions in the right coronary artery (RCA), coronary artery dissection in the ostium of the RCA is a rare but fatal complication. Stent implantation to the ostium of RCA may be selected for the prevention of aorto-ostial dissection. AIM: To find factors associated with aorto-ostial stent coverage to mild to moderate ostial stenosis during the treatment of severely narrowed non-ostial RCA lesions. MATERIAL AND METHODS: = 184). CONCLUSIONS: Continuous ostial plaque detected by IVUS was significantly associated with ostial stent coverage to the mild to moderate stenosis when PCI to non-ostial, severely narrowed RCA lesions was performed. The use of IVUS may enhance the safety but may increase the total stent length in PCI to RCA.
