Pre-procedural 3DCT Versus Angiography Guided PCI for Ostial Right Coronary Artery Lesions

A contrast CT-scan of the coronary arteries will be performed and 3D analyzed to determine the best angle for the C-arm during Percutaneous Coronary Intervention (PCI) for stent implantation. Furthermore determining the amount and localization of calcium in the right coronary artery (RCA) and diameter and length of RCA. The use of IVUS will be used to determine the degree of calcium.

Standard of care is angiography guided PCI of the ostium of the RCA. The use of IVUS will be used to determine the degree of calcium.
