Clinical use of optical coherence tomography and fractional flow reserve
Insights
Angiography alone is insufficient for guiding myocardial revascularization in complex coronary artery disease. Combining fractional flow reserve (FFR) and optical coherence tomography (OCT) improves treatment decisions and outcomes, especially for recurrent in-stent restenosis.
Area of Science:
- Cardiovascular diagnostics
- Interventional cardiology
- Medical imaging analysis
Background:
- Myocardial revascularization decisions require accurate stenosis assessment.
- Angiography alone provides insufficient morphological evaluation for borderline coronary artery stenosis.
- Advanced diagnostic tools are essential for comprehensive patient treatment guidance.
Observation:
- Optical coherence tomography (OCT) revealed non-lumen stenosis in a case report.
- Fractional flow reserve (FFR) and OCT demonstrated complementary roles in complex coronary disease.
- OCT proved significant in managing recurrent stent restenosis.
Findings:
- Percutaneous coronary intervention (PCI) guided solely by angiography is inadequate for complex coronary disease.
- FFR and OCT serve as complementary methods to enhance revascularization quality.
- These advanced techniques are particularly beneficial for recurrent in-stent restenosis.
Implications:
- Integrating FFR and OCT can optimize treatment strategies for myocardial revascularization.
- Improved diagnostic accuracy leads to better patient outcomes in complex coronary cases.
- This approach enhances the effectiveness of interventions for challenging restenosis scenarios.
Introduction:
The aim of each diagnostic method is to serve as a guide in deciding about the right patient treatment. During myocardial revascularization the decision to perform revascularization is usually not easy to make, especially in case of borderline stenosis. It has been proven that it is not enough to base morphological evaluation of coronary artery vessel stenosis solely on angiography. It is necessary to include additional modern diagnostic methods for functional analysis and detailed morphological analysis using fractional flow reserve (FFR) and optical coherence tomography (OCT), respectively.
Case Reports:
In the first case report we showed the significance of morphological analysis using OCT and proved that it was not lumen stenosis. The second and the third case reports showed the complementarity between functional analysis (FFR) and morphological analysis (OCT) of stenosis in solving a complex coronary disease. The fourth case report showed the significance of OCT in dealing with the recurrent stent restenosis.
Conclusion:
By these short case reports we confirmed that percutaneous coronary intervention (PCI) guided by angiography is definitely not enough in deciding about myocardial revascularization especially in patients with a complex coronary disease. In certain cases FFR and OCT procedures can be complementary methods and improve quality of revascularization, particularly in case of recurrent in-stent restenosis.
