A case report of virtual reality-guided percutaneous coronary intervention for anomalous origin of right coronary artery chronic total occlusion

Background Engagement of the guiding catheter (GC) for the coronary artery is sometimes difficult, depending on the patient's anatomy. The most suitable GC before percutaneous coronary intervention (PCI) in individual cases has not been determined yet. Case summary An 81-year-old woman who had a right coronary artery chronic total occlusion had difficulty to engage the catheter for the right coronary artery in the first examination. Virtual reality (VR)-guided GC simulation before PCI using cardiac computed tomography (CT) could overcome the difficulty of GC engagement for the coronary artery and achieve procedure success. Discussion VR-guided GC simulation has the potential to solve the catheter approach difficulty for any cardiovascular intervention.
