Diagnostic Performances of Computed TomographIc Coronary Angiography and Intravascular Ultrasound (IMAGES-FFR)
|Diagnosis Coronary Artery Disease||Procedure: diagnostic procedures CCTA, CAG, IVUS and FFR|
|Study Design:||Observational Model: Cohort
Time Perspective: Prospective
|Official Title:||Diagnostic Performances of the Computed Tomographic Coronary Angiography and IntraVascular UltraSound to Evaluate Ischemia Causing Coronary Artery Stenosis|
- Diagnostic accuracy [ Time Frame: 1 day ]
Evaluate and compare the diagnostic accuracy of the CCTA, IVUS and angiographic parameters for the prediction of myocardial ischemia (FFR<0.8)
- CCTA: % area stenosis
- IVUS: minimum lumen area
- Angiography: % diameter stenosis
Diagnostic accuracy of each parameter: (true positive+true negative)/total cases
|Study Start Date:||March 2008|
|Study Completion Date:||December 2011|
|Primary Completion Date:||December 2011 (Final data collection date for primary outcome measure)|
Patients suspected ischemic heart disease by the symptom and CCTA and undergone IVUS and FFR in the Cath Lab with CAG enrolled consecutively.
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.
Correlation between CCTA, IVUS and FFR will be evaluated. The presence of myocardial ischemia will be assessed by fractional flow reserve (FFR).
Diagnostic performance (sensitivity, specificity, positive predictive/negative predictive values and diagnostic accuracy) of each modality will be assessed and compared.
