Patient-Specific Three-Dimensional Aortocoronary Model for Percutaneous Coronary Intervention of a Totally Occluded Anomalous Right Coronary Artery.

Percutaneous coronary intervention (PCI) for anomalous coronary arteries is often difficult because the support provided by the guide catheter is insufficient. We encountered a patient with severe three-vessel coronary disease including a totally occluded anomalous right coronary artery (RCA) originating from the left sinus of Valsalva. Initial PCI for the anomalous RCA via the transradial approach failed.
