    1. The year in cardiology: acute coronary syndromes: The year in cardiology 2019

      The year in cardiology: acute coronary syndromes: The year in cardiology 2019

      The mechanisms and the pathologic substrate of plaque erosion and plaque fissure are different. Indeed, plaques complicated by erosion tend to be matrix-rich, lipid-poor, and usually lack prominent macrophage collections, unlike plaques that rupture, which characteristically have thin fibrous caps, large lipid pools, and abundant foam cells. 9 In a prospective study in 211 patients with STEMI who underwent pre-intervention optical coherence tomography (OCT) examination for the culprit lesion, Tan et al . 10 found that trimethylamine N-oxide (TMAO) levels, a gut microbiota-dependent metabolite derived from dietary phosphatidylcholine and choline, were significantly and independently higher in patients with plaque fissure than ...

    2. The year in cardiology 2019: Acute Coronary Syndromes

      The year in cardiology 2019: Acute Coronary Syndromes

      The management of acute coronary syndromes (ACS) has made enormous progress over the last five decades due to the introduction of defibrillation, beta blockers, thrombolytics, aspirin, primary percutaneous transluminal intervention (PCI), P 2 Y 12 inhibitors, statins, radial access, and eventually PCSK9 inhibitors, among others. 1 However, in spite of all these remedies, there is a remaining acute mortality risk, in particular, in those presenting in cardiogenic shock or after resuscitation and an accruing number of major cardiovascular events (MACE) over the following years. 2 Thus, there is an unmet need in the management of ACS. In 2019, there were ...

    3. The impact of blood pressure variability on coronary arterial lumen dimensions as assessed by optical coherence tomography in patients with ST-elevation myocardial infarction

      The impact of blood pressure variability on coronary arterial lumen dimensions as assessed by optical coherence tomography in patients with ST-elevation myocardial infarction

      Background Patients with ST-elevation Myocardial Infarction treated by primary percutaneous coronary intervention (PPCI) experience drastic hemodynamic systemic changes (i.e., blood pressure) during the different phases of the procedure. Optical coherence tomography is often used to unveil the underlying cause of STEMI (pre-PCI) and to optimize stent implantation (post-PCI). The impact of blood pressure variability on coronary lumen remains uncertain. This study aimed to investigate the relationship between blood pressure variability, before and after PCI, and coronary arterial lumen dimensions of the infarct-related artery. Methods We measured systolic, diastolic and mean arterial blood pressure (SBP, DBP, and MAP; respectively) at ...

    4. Dual quantitative coronary angiography accurately quantifies intracoronary thrombotic burden in patients with acute coronary syndrome: Comparison with optical coherence tomography imaging

      Dual quantitative coronary angiography accurately quantifies intracoronary thrombotic burden in patients with acute coronary syndrome: Comparison with optical coherence tomography imaging

      Background Dual quantitative coronary angiography (QCA) has been recently tested for assessment of intracoronary thrombus volume in experimental models. The present study aimed to validate dual QCA in vivo for the assessment of thrombus burden by exploring the correlations between dual QCA-thrombus volume and optical coherence tomography (OCT)-derived indices of thrombotic burden. Methods and results Fifty-one patients with ACS and angiographic evidence of thrombus undergoing OCT of the culprit lesion before stenting were included. Dual QCA-thrombus volume was calculated as difference between edge-detection and video-densitometry area functions along the target segment. Culprit lesion was categorized using the Ambrose's ...

    5. Transverse partial stent ablation with rotational atherectomy for suboptimal culotte technique in left main stem bifurcation

      Transverse partial stent ablation with rotational atherectomy for suboptimal culotte technique in left main stem bifurcation

      Longitudinal rotational atherectomy of metal struts is well described as bail-out strategy to treat undilatable instent restenosis. Ablation of metal stent struts jailing the ostium of a major side branch in a coronary bifurcation is not described. In the current report, we describe a case of “transverse” rotational atherectomy to treat a failure of culotte stenting in a left main stem bifurcation. We document for the first time in vivo and in man the effect of this strategy using optical coherence tomography.

    6. Optical coherence tomography to guide percutaneous treatment of coronary bifurcation disease

      Optical coherence tomography to guide percutaneous treatment of coronary bifurcation disease

      Introduction : Cardiovascular disease remains the most common cause of death worldwide. Enormous progress in the technology and applicability of percutaneous techniques to treat obstructive coronary heart disease has been made, and the number of percutaneous coronary interventions (PCI) is increasing. Coronary bifurcations are involved in a substantial number of PCIs and despite recent advances, bifurcation PCI remains a challenge in terms of immediate success and long-term outcome. Angiography has a limited capacity for showing important features of the 3 dimensional coronary vessel anatomy, position of stent struts and exact wire positions and is therefore suboptimal for guiding bifurcation PCI. Intracoronary ...

    7. Management and optical coherence tomography imaging of an acute coronary artery injury induced by radiofrequency catheter ablation

      Management and optical coherence tomography imaging of an acute coronary artery injury induced by radiofrequency catheter ablation

      Catheter ablation with radiofrequency (RF) is the treatment of choice for atrio-ventricular reentrant tachycardias. In case of posterior or postero-lateral accessory pathways, epicardial RF ablation from within the coronary sinus (CS) may be warranted, but since both the left circumflex (LCx) coronary artery and the CS lie on the epicardial surface of the atrioventricular groove, LCx injury with possible acute occlusion or sub-total occlusion can occur.
