    1. Combined Use of OCT and IVUS in Spontaneous Coronary Artery Dissection

      Combined Use of OCT and IVUS in Spontaneous Coronary Artery Dissection

      Spontaneous coronary artery dissection (SCD) is a rare clinical entity ( 1 and 2 ). Clinical diagnosis is challenging and classically relies on the angiographic demonstration of an intimomedial “flap” leading to a double lumen appearance ( 1 and 2 ). Angiography, however, is unable to visualize the coronary wall. New intracoronary diagnostic tools provide comprehensive, tomographic, high-resolution insights on vessel wall pathology, allowing a precise diagnosis of SCD ( 3 and 4 ). A 58-year-old woman presented with a non–ST-segment elevation inferior myocardial infarction. Angiography ( Fig. 1 A) revealed a normal right coronary artery with just minor lumen irregularities. Intravascular ultrasound (IVUS) ( Fig. 1 ...

    2. Endovascular imaging of angiographically invisible spontaneous coronary artery dissection.

      Endovascular imaging of angiographically invisible spontaneous coronary artery dissection.

      Combined Use of IVUS and OCT in SCD(A) Coronary angiography showing a right coronary artery without significant coronary stenosis. (B) IVUS imaging disclosing the presence of a large space (asterisks) separating the intimomedial membrane from the external elastic membrane. The coronary lumen was largely preserved (minimal lumen diameter: 3.5 mm). (C) OCT unraveling (arrow) the intimal tear in the proximal right coronary artery with an anfractuous entrance into the coronary vessel wall. (D) An image of intramural hematoma was demonstrated in the mid and distal segments of the vessel. In most segments, the outer boundaries of the vessel ...

    3. Combined use of optical coherence tomography and intravascular ultrasound imaging in patients undergoing coronary interventions for stent thrombosis

      Combined use of optical coherence tomography and intravascular ultrasound imaging in patients undergoing coronary interventions for stent thrombosis

      Objective This prospective study sought to assess the diagnostic value of optical coherence tomography (OCT) compared with intravascular ultrasound (IVUS) in patients presenting with stent thrombosis (ST). Design and setting Although the role of IVUS in this setting has been described, the potential diagnostic value of OCT in patients suffering ST remains poorly defined. Catheterization Laboratory, University Hospital. Patients and interventions Fifteen consecutive patients with ST undergoing rescue coronary interventions under combined IVUS/OCT imaging guidance were analysed. Mean outcome measures Analysis and comparison of OCT and IVUS findings before and after interventions. Results Before intervention, OCT visualised the responsible ...

    4. Diagnosis of Spontaneous Coronary Artery Dissection by Optical Coherence Tomography

      Diagnosis of Spontaneous Coronary Artery Dissection by Optical Coherence Tomography

      Objectives: This study sought to assess the diagnostic value of optical coherence tomography (OCT) in patients with suspected spontaneous coronary artery dissection (SCAD).Background: SCAD is a rare but challenging clinical entity. Methods: Following a prospective protocol, OCT was performed in 17 consecutive patients with a clinical and angiographic suspicion of SCD from a total of 5,002 patients undergoing coronary angiography. A conservative management strategy was followed. Results: OCT ruled out the diagnosis of SCAD in 6 patients with coronary artery disease (atherosclerotic plaques and/or intracoronary thrombus). In 11 patients (age 48 ± 9 years, 9 female), OCT confirmed ...

    5. Detection of very early stent healing after primary angioplasty: an optical coherence tomographic observational study of chromium cobaltum and first-generation drug-eluting stents. The DETECTIVE Study

      Detection of very early stent healing after primary angioplasty: an optical coherence tomographic observational study of chromium cobaltum and first-generation drug-eluting stents. The DETECTIVE Study

      Background Lack of stent coverage appears to be associated with stent thrombosis, a problem of particular concern in patients with ST elevation myocardial infarction (STEMI). Methods The DETECTIVE European Multicenter Registry was set up to address the early modality of stent healing in the setting of STEMI. The Registry compared, with an early optical coherence tomography (OCT) evaluation performed at 3–7 days, the patterns of coverage and apposition of the first generation of drug-eluting stents (DESs) and cobalt chromium non-drug-eluting stents (CCSs) that were deployed in culprit lesions and in non-culprit segments. The Registry included only patients with a ...

    6. Treatment of a Giant Coronary Artery Aneurysm: Intravascular Ultrasound and Optical Coherence Tomography Findings

      Treatment of a Giant Coronary Artery Aneurysm: Intravascular Ultrasound and Optical Coherence Tomography Findings

      A giant coronary aneurysm (GCA) partially thrombosed was demonstrated in a 77-year-old patient evaluated for an inferior myocardial infarction. Primary angioplasty (balloon only) with suboptimal result was initially obtained. After triple antiplatelet and anticoagulation therapy (4 days), a new angiography was performed and a fusiform GCA was clearly delineated. A second percutaneous intervention was performed using a “scaffolding technique” with conventional stent and subsequent implantation of 2 polytetrafluoroethylene-covered stents to successfully exclude the aneurysm. This case demonstrates a novel technique to treat long GCA
