Optical coherence tomographic image of an angiographically borderline lesion with a significant fractional flow reserve.
42-year-old diabetic woman presented with left ventricular dysfunction late after an Aanterior wall myocardial infarction. Fluoro-deoxy glucose-positron emission tomography showed viability in the left anterior descending artery (LAD) territory. Coronary angiogram (A, Online Video 1) showed a significant mid-LAD disease which was stented. Fractional flow reserve (B) done for the borderline lesi...
متن کاملComparison of cardiac magnetic resonance imaging and positron emission tomography for the diagnosis and localization of coronary artery disease
Methods 22 patients with known or suspected CAD underwent both N-Ammonia PET and CMR adenosine stress and rest perfusion imaging prior to diagnostic coronary Xray angiography (CXA). CMR perfusion imaging was performed at 1.5T with a kt-accelerated steady-state free-precession sequence. Data analysis was blind. A significant coronary artery stenosis was defined as at least 70% diameter reduction...

متن کاملFractional flow reserve or optical coherence tomography guidance to revascularize intermediate coronary stenosis using angioplasty (FORZA) trial: study protocol for a randomized controlled trial
BACKGROUND The management of patients with angiographically intermediate coronary lesions is a major clinical issue. Fractional flow reserve provides validated functional insights while optical coherence tomography provides high resolution anatomic imaging. Both techniques may be applied to guide management in case of angiographically intermediate coronary lesions. Moreover, these techniques ma...
متن کاملAssessment of diagnostic performance of quantitative flow measurements in normal subjects and patients with angiographically documented coronary artery disease by means of nitrogen-13 ammonia and positron emission tomography.
OBJECTIVES Regional myocardial blood flow (MBF) and flow reserve measurements using nitrogen-13 (N-13) ammonia positron emission tomography (PET) were compared with quantitative coronary angiography to determine their utility in the detection of significant coronary artery disease (CAD). BACKGROUND Dynamic PET protocols using N-13 ammonia allow regional quantification of MBF and flow reserve....
