Multimodality Imaging and Functional Lesion Assessment in Intermediate Grade Coronary Stenosis in Chronic Coronary Syndrome: MultiInter-CCS Study
The aim of this prospective, investigator-initiated study is to evaluate the diagnostic accuracy and correlations between functional indices (fractional flow reserve, FFR) and morphometric indices: luminal and qualitative parameters assessed by optical coherence tomography (OCT) including minimal lumen area, plaque type, presence of thin cap fibroatheroma among patients with chronic coronary syndrome identified with intermediate grade coronary stenosis.
• 18 years or older
• Chronic coronary syndrome defined as presence of chest pain ranked 2-3 in the Canadian Cardiovascular Society classification or positive ischemia test (exercise test, single photon emission tomography (SPECT)
• Intermediate grade coronary stenosis of 40-80% assessed visually in coronary angiography
• FFR and OCT examination of the same lesion
• The patient is willing to participate in the study and has provided a written informed consent
