Abstract:
Thin-cap fibroatheromas (TCFA) are prone to plaque rupture and thrombosis. Intravascular ultrasound (IVUS) virtual histology (VH) assesses plaque composition and lesion morphology in vivo. Methods & Results: We used serial (baseline and follow-up @11 mos) VH-IVUS to study non-culprit plaque morphology in 221 lesions (plaque burden >40%) in 106 pts. Lesions were classified into 4 types based on plaque composition; pathological intimal thickening (PIT), thin-capped fibroatheroma (TCFA), thick-capped fibroatheroma (ThCFA), fibrotic/fibrocalcific. At baseline, 21 lesions were TCFAs (conflue

Abstract:
Objectives: Intravascular optical coherence tomography (IVOCT) images are recorded by detecting light backscattered within coronary arteries. We hypothesize that non- thin-cap fibroatheroma (TCFA) etiologies may scatter light to create the false appearance of IVOCT TCFA. Background: Conflicting reports are recognized about the accuracy of IVOCT for TCFA detection. Methods: Ten human cadaver hearts were imaged with IVOCT (N=14 arteries). Coronary arteries were sectioned at 120 μm intervals. IVOCT and histologic TCFA were co-registered and compared. Results: Of 21 IVOCT TCFAs identified by two i

Abstract:
Background: ST-elevation myocardial infarction (STEMI) that occurs during the off hours shows worse clinical status compared to the patients presenting during working hours. Method: We used Virtual Histology Intravascular Ultrasound (VH-IVUS) to assess the complexity of culprit lesion in 193 patients with STEMI. The patients were divided into two groups that presented to the hospital during the working hours (from 8:30 am to 6:00 pm) and the off hours (from 6:00 pm to 8:30 am of the next day). VH-TCFA (thin-capped fibroatheroma) was defined as necrotic core (NC) >10% of plaque area with a p

Abstract:
Backgrounds: The aim of the present study is to investigate the relationship between physiological coronary artery stenosis severity and lesion instability by Optical Coherence Tomography (OCT) in patients with stable angina pectoris (SAP). Methods and Results: We investigated 198 culprit lesions of 180 SAP patients who underwent OCT imaging and fractional flow reserve (FFR) measurement before PCI procedure. Physiological coronary stenosis severity was assessed by FFR analysis, and lesions were divided into two groups on the basis of FFR values; severe stenosis group (group S): FFR <0.75 (n

Abstract:
Η οπτική συνεκτική τομογραφία με τη χρήση συχνοτήτων ( FD-OCT) είναι μια ενδαγγειακή απεικονιστική μέθοδος που χρησιμοποιεί εγγύς στο υπέρυθρο φως, για να παράγει υψηλής ανάλυσης εικόνες του τοιχώματος του αυλού του αγγείου. Όπως και στην τεχνολογία υπερήχων, εκπέμπεται φωτεινή ενέργεια η οποία ανακλάται και εξασθενεί, σύμφωνα με την υφή του προσπιπτομένου ιστού. Το OCT μπορεί να απεικονίσει, με ανάλυση από 10 έως 20 μm, μικροδομές του αγγειακού τοιχώματος με εξαίσια λεπτομέρεια. Μέχρι σήμερα, η δυνατότητα εφαρμογής της μεθόδου είχε περιοριστεί σε μικρές αρτηρίες διαμέτρου έως 4mm και δεν είχ
