Assessment and Characterization of Time-related Differences in Plaque Composition by Intravascular Ultrasound-derived Radiofrequency Analysis in Heart Transplant Recipients

IVUS-RF, as compared with gray-scale IVUS, provides better detailed information about the development of CAV by plaque morphology and composition analysis in different stages after heart transplantation. Serial IVUS-RF analysis in these patients may improve the stratification of heart transplant recipients.
