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

Coronary Artery Disease Clinical Trial

Official title:
Pre-procedural 3D Reconstructed Computer Tomography Versus Angiography Guided Percutaneous Coronary Intervention for Ostial Right Coronary Artery Lesions

Clinical Trial Summary

Even with second generation drug eluting stents, rates of target lesion failure (TLF) for aorto-ostial RCA lesions remain high [3yrs TLF 14.2%]. Retrospective studies show that stent underexpansion and geographical stent-ostium mismatch are the main predictors for TLF. Geographical mismatch means that the stent is implanted either too distal (thereby not fully covering the lesion) or too proximal (thereby protruding too much in the aorta and hampering future engagement with guiding catheters). The investigators hypothesize that, pre-procedural 3D CT coronarography to determine the optimal C-arm angle of the X-ray system with the most accurate visualization of the aorto-ostial angle and determination of localization of calcium, could prevent geographical mismatch.
