No results posted yet for this study

Summary

Diagnostic purposes of the coronary angiography is to detect stenosis (anatomy) and to detect ischemia related stenosis (function). Coronary angiography (CAG) is a gold standard invasive techniques, but has several limitations. Intravascular ultrasound (IVUS) provides tomographic intra-luminal images. Coronary computed tomographic angiography (CCTA) is helpful to assess precise anatomical information. Optimal functional criteria and their accuracy of IVUS and CCTA by fraction flow reserve (FFR) have not been compared yet.

Conditions

  • Diagnosis Coronary Artery Disease

Interventions

PROCEDURE

diagnostic procedures CCTA, CAG, IVUS and FFR

Diagnostic procedures including computed tomography, coronary angiography, intravascular ultrasound, fractional flow reserve were performed in the patients suspected ischemic heart disease.
