    1. OCT-Guided Percutaneous Coronary Intervention In Bifurcation Lesions

      OCT-Guided Percutaneous Coronary Intervention In Bifurcation Lesions

      Coronary artery bifurcation lesions remain challenging despite significant advancements in stent technology and development of specific bifurcation stenting approaches. Optical coherence tomography (OCT) is the intracoronary imaging technique with the highest resolution and can generate automatically contoured lumen areas across the variable geometry of bifurcation lesions. Knowledge of plaque severity and composition facilitates planning of the best strategy for percutaneous coronary intervention (PCI) and stenting. In particular, the provisional stent strategy preferred in this context can be modified when there is high risk of side-branch compromise at the ostium after main vessel stenting. OCT is unique because it allows the ...

    2. Absorb vs. DESolve: an optical coherence tomography comparison of acute mechanical performances

      Absorb vs. DESolve: an optical coherence tomography comparison of acute mechanical performances

      Aims: The aim of the study was to compare retrospectively the acute mechanical performance of the Absorb vs. DESolve scaffolds in terms of appropriate deployment with OCT. Methods and results: Final post-deployment OCT pullbacks of consecutive patients treated with either Absorb or DESolve were reviewed. The following parameters were calculated and compared: mean and minimal lumen area (MLA), residual in-scaffold area stenosis (RAS), incomplete strut apposition (ISA), tissue prolapse area, eccentricity index, asymmetry index, strut fracture and edge dissection. A total of 72 patients were included. The Absorb group consisted of 35 patients treated with 63 Absorb scaffolds and was ...

    3. Optical Coherence Tomography Assessment and Quantification of Intracoronary Thrombus: Status and Perspectives

      Optical Coherence Tomography Assessment and Quantification of Intracoronary Thrombus: Status and Perspectives

      Coronary angiography is the “golden standard” imaging technique in interventional cardiology and it is still widely used to guide interventions. A major drawback of this technique, however, is that it is inaccurate in the evaluation and quantification of intracoronary thrombus burden, a critical prognosticator and predictor of intraprocedural complications in acute coronary syndromes. The introduction of optical coherence tomography (OCT) holds the promise of overcoming this important limitation, as near-infrared light is uniquely sensitive to hemoglobin, the pigment of red blood cells trapped in the thrombus. This narrative review will focus on the use of OCT for the assessment, evaluation ...

    4. ABSORB Biodegradable Stents Versus Second-Generation Metal Stents : A Comparison Study of 100 Complex Lesions Treated Under OCT Guidance

      ABSORB Biodegradable Stents Versus Second-Generation Metal Stents : A Comparison Study of 100 Complex Lesions Treated Under OCT Guidance

      Objectives The aim of this study was to compare the acute performance of the PLLA ABSORB bioresorbable vascular scaffold (BVS) (Abbott Vascular, Santa Clara, California) with second-generation metal drug-eluting stents (DES) in complex coronary artery lesions. Background Thick polymer-based BVS have different mechanical properties than thin second-generation DES. Data on the acute performance of BVS are limited to simple coronary lesions treated in trials with strict inclusion criteria. Methods Fifty complex coronary lesions (all type American College of Cardiology/American Heart Association B2-C) treated with a BVS undergoing a final optical coherence tomography (OCT) examination were compared with an equal ...

    5. Prospectively electrocardiogram-triggered high-pitch spiral acquisition coronary computed tomography angiography for assessment of biodegradable vascular scaffold expansion: Comparison with optical coherence tomography

      Prospectively electrocardiogram-triggered high-pitch spiral acquisition coronary computed tomography angiography for assessment of biodegradable vascular scaffold expansion: Comparison with optical coherence tomography

      BVS polymeric struts are transparent to the light so that the vessel wall contour can be easily visualized using optical coherence tomography (OCT). Therefore OCT represents a unique tool for both the evaluation of the resorption process and for the assessment of acute BVS mechanical failure. Similarly, the metal-free struts allow unrestricted coronary computed tomography angiography (CCTA), thus this non invasive method might become the gold standard for a non invasive assessment of BVS. In this case we show the ability of CCTA, performed with a low X-Ray dose, to provide a good evaluation of scaffold expansion. The quantitative measurements ...

    6. Coronary artery aneurysm following stent implantation: insights from serial multiple intravascular imaging modalities

      Coronary artery aneurysm following stent implantation: insights from serial multiple intravascular imaging modalities

      Coronary artery aneurysms after coronary intervention are rare and most ‘aneurysms’ are, in fact, pseudoaneurysms rather than true aneurysms. A correct diagnosis is mandatory for optimal management of this rare coronary complication. Intravascular ultrasound (IVUS) has become the gold standard for providing crucial information on the anatomical composition of the vessel wall, necessary to achieve the diagnosis. On the other hand, optical coherence tomography (OCT) is the most accurate diagnostic tool for providing luminal coronary measurement,
