ABSTRACT
OBJECTIVE:
Previous studies have demonstrated the benefit of intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) for preventing longitudinal geographic miss (LGM). However, it is yet unclear whether IVUS guidance is useful for robotic-PCI (robotic-assisted perctaneous coronary intervention [R-PCI]).METHODS:
A total of 58 consecutive patients with stable angina who underwent IVUS-guided R-PCI were enrolled. The stent landing position was angiographically marked using a balloon marker before stenting, followed by measurements of the expected stent length using balloon pullback. Subsequently, prestenting IVUS was performed to determine stent landing. All pre-PCI IVUS images were assessed for lesion length and percent plaque volume (%PV) using both IVUS and angiographic marking. LGM was defined as a residual %PV >50% at either the distal or proximal stent edge, any stent edge dissection, or additional stent deployment immediately after stenting.RESULTS:
The included patients had an average age of 67.1 ± 10.1 years. IVUS guidance had significantly longer lesion lengths compared with angiographic marking. Based on IVUS-guided stent deployment, nine cases exhibited LGM immediately after stenting. IVUS-marked landing points had a significantly smaller %PV and significantly larger lumen area compared with those for angiography.CONCLUSION:
IVUS-guided R-PCI was well-tolerated and may be better at preventing LGM compared with angiography-guided R-PCI.
