Functional and Clinical Benefits of PCI in Patients With CTO
Multimodality Imaging Evaluation of Functional and Clinical Benefits of Percutaneous Coronary Intervention in Patients With Chronic Total Occlusion Lesion
研究概览
详细说明
Noninvasive imaging modalities have shown high diagnostic accuracy in the detection of coronary artery lesions, and for the estimation of their hemodynamic relevance.Thus, noninvasive assessment of myocardial perfusion defects may be preferred for patients with chronic total occlusion (CTO).
In particular, myocardial perfusion is measured with single photon emission CT (SPECT).Multislice coronary CT angiography (CCTA) with dual-source scanners reveals the anatomic location of coronary artery disease (CAD). These two techniques assess distinct aspects of heart morphology and function parameters of the heart, and should therefore be regarded as complementary rather than competing methods.Taking this into consideration, decisions regarding whether invasive revascularization therapy is adequate or not and which strategy is the best for long-term survival cannot be supported by anatomic information alone. Therefore, noninvasive complementary imaging of structure and perfusion, in conjunction with three-dimensional (3D) image fusion, has emerged as a technique for reliable allocation of perfusion defects to their supplying coronary artery.
