First Experience of Robotic-assisted Percutaneous Coronary Intervention in Japan

Abstract

In 2018, the CorPath GRX system (Corindus) was approved for use in Japan, marking the introduction of the first robotic-assisted system for percutaneous coronary intervention (PCI) in the country. The present report describes the first experience of robotic-assisted PCI for four coronary lesions in two cases in a single center. All procedures succeeded without any complications, although one procedure was converted to manual PCI by the operator's decision. Post-marketing surveillance to assess the impact of this novel system on both Japanese patients and physicians is currently ongoing in Japan.

Keywords: coronary artery disease; interventional innovation; percutaneous coronary intervention; robotic technology.

Case 1. Robotic-assisted PCI for the RCA lesion and LCX lesion. A: Coronary angiography revealed tight stenosis in the mid RCA. B: After robotically wiring across the lesion and predilation with a 2.5×15-mm balloon, a 3.0×32-mm Synergy stent was delivered robotically and deployed. C: The final angiogram showed an excellent result. D: Coronary angiography revealed severe stenosis in the mid LCX. E: After robotically wiring across the lesion and predilation with a 2.25×15-mm balloon, a 2.25×38-mm XIENCE Sierra stent was delivered robotically and implanted. F: An excellent result was obtained.
