Insights
Detecting restenosis after coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI) is crucial. This review covers non-invasive cardiac imaging techniques for assessing patients post-revascularization.
Area of Science:
- Cardiology
- Medical Imaging
Background:
- Obstructive coronary artery disease (CAD) management involves percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG).
- A significant risk of restenosis persists after both PCI and CABG.
- Early detection of in-stent restenosis or graft disease is clinically vital.
Purpose of the Study:
- To provide an overview of non-invasive cardiac imaging techniques.
- To identify methods for assessing patients after revascularization procedures.
- To highlight the importance of accurate non-invasive assessment for guiding subsequent invasive coronary angiography (ICA).
Main Methods:
- Review of existing literature on non-invasive cardiac imaging modalities.
- Focus on techniques applicable to patients post-PCI or CABG.
- Discussion of both anatomic and functional imaging approaches.
Main Results:
- Several non-invasive cardiac imaging techniques can assess patients after revascularization.
- These methods aid in identifying restenosis or graft disease.
- Non-invasive assessment can help select patients who would benefit from invasive coronary angiography.
Conclusions:
- Non-invasive cardiac imaging plays a key role in managing patients post-PCI and CABG.
- Accurate assessment facilitates timely intervention for restenosis.
- These techniques offer a valuable alternative or adjunct to routine invasive angiography.
Abstract:
In the management of patients with obstructive coronary artery disease (CAD), percutaneous coronary intervention (PCI) with stent implantation is routinely performed. In patients with left main or three-vessel disease, however, coronary artery bypass grafting (CABG) may be the preferred therapeutic strategy. Importantly, both after PCI or CABG a small but non-negligible risk of restenosis remains. Early detection and treatment of in-stent restenosis or graft disease is of great clinical importance. Accordingly, accurate non-invasive methods to identify patients who would benefit from subsequent invasive coronary angiography (ICA) would be highly beneficial. Besides ICA, several non-invasive cardiac imaging techniques may be used to assess patients after revascularisation. In the present article, an overview of various anatomic and functional imaging techniques available to assess patients after revascularisation is provided.
